Hands-down the best adjustment I’ve ever had. John is fantastic! He’s very knowledgeable and ensures that his patients are comfortable and relaxed. I came into the facility unable to move my neck, walked out with full mobility. Their pricing is more than reasonable and they offer a money-saving membership program, which I’m definitely taking advantage of. I’ve definitely found my new regular chiropractor!

THIS IS THE PLACE!!!This is where I go for all my chronic pain. I don't need to have an appointment for an adjustment, I walk in and get a CBD massage and immediately after get my neck adjusted. This combo is the only one that makes my pain go away. The staff is always so great and humorous which is also what i need for pain management.

I found back in a Flash years ago when they just opened in Up Town. The business, the quality, the service are outstanding. I come here regularly to relieve the pressures of life. Dr John Perea gets in there, right where I need it, every time. He takes his time, is intuitive, achieves consistent results with friendly service.

Dr John has been taking care of my spine and well being for many years. I go to him when I need a good alignment and he always comes through. I feel 10 years younger when I walk out of his office!!!

This place is amazing!  Nice neighborhood, plenty of parking, and beautifully decorated.  Dr. John greeted me and thoroughly explained the process and benefits from getting adjustments.  He was able to adjust me right away, it was the best adjustment I have ever had.  No hesitation, he knew exactly where I needed help and was able to adjust me easily.  I was blown away.  Then I had a message by Selina.  It wasn't just an ordinary message, she used the Ashiatsu technique and my god I have never felt such deep tissue relief, and it was with her smooth feet!  I was amazed at how talented she is and how strong her feet are.  It was unreal!  I think almost every muscle was addressed and given much attention to make every knot I had relax.  I have never had a massage as effective as hers.  I highly recommend this technique!  I will be definitely be returning and getting on a routine schedule.   Thank you both for being so talented and giving me relief!

Dr. John and Adam both were amazing!! After a great massage by Adam, John gave me a realignment. First time ever doing it and I feel like a new man. I slept for the first time on the back of my head without waking up with a headache in about 10 years. These 2 gentlemen are highly recommended!! See y’all soon.

Back in a Flash Chiropractic is what I would call a heavenly experience. Selina took incredible care of me and I can honestly say I haven't had a better massage than hers in a few years. I was also extremely happy to know that they have one of the best float tanks in Denver! (which is a sensory deprivation tank). Seriously, that little room is a trip to a different planet.If you are looking to get adjusted after a nice CBD massage, please go see Dr. John. He's hands down the best chiropractor in Denver, and I have been to many. I love my chiropractor!

John is great. Feeling way better w/ regular visits

I am a yoga practitioner and facilitator, so my alignment is usually decent, but after a summer internship of intense trailwork on CO'S 14ers, my spine is definitely in rough shape and needs some extra help. A friend recommended Dr. John, and I'm so so glad I went. The service is fairly quick and no-nonsense, and John seems to know just where to look and exactly how to adjust you. I am excited to head back and try their float tank and massage services.

John Perea has always always given adjustments with maximum release in my neck and hips, appointments or walk-ins are always fast and efficient. The best part is that Back in a Flash is more affordable than most Chiro places.

I've been suffering from extreme neck and shoulder pain, literally waking up in the middle of night with discomfort. This has been going on for nearly 1.5 months and I find it painful to look to the right while driving and doing almost everything. I tried treating my issue with massage which marginally helped, but I felt the pain to be deeper then simply muscles. I found Back in a flash... and all I can say is WOW and THANK GOD After one session my issue was improved by at least 70%, just had my second session today and I can tell by his (Dr. John) methodology, which is intricate and no none sense that I am on the right track. The treatments are thorough and efficient and EFFECTIVE! I am so beyond grateful that I found this place!

Dr Perea is amazing!!! I’ve never experienced such an awesome adjustment like that before. He was very informative and talks you through the whole process before and during the session. Highly recommended!!

Felt I was in good hands with a knowledgeable doctor, I was adjusted and though I feel a little better I think this willBe the place I will keep going to actually try to get better and not just feel better temporarily.

Highly recommended. We travel 40 minutes to see Dr. John. The best service in the industry.

Dr John is wonderful he is helping me with my tingle in my fingers

John Perea has always always given adjustments with maximum release in my neck and hips, appointments or walk-ins are always fast and efficient. The best part is that Back in a Flash is more affordable than most Chiro places.

Today was my first time getting an adjustment and Dr. John made it super quick and easy! He is very knowledgeable in his field and helped everything make sense. I immediately could feel the difference in my back.

Love the chiropractor and massage therapist Eve

I love this place, wouldn't even consider going anywhere else. Kind, friendly service and I leave feeling like a new person every time

John is amazing, very attentive to your specific issues, and is very friendly. Visits are easy to schedule, very convenient and efficient. Great atmosphere. Highly recommend!

John fixed a 5 year neck mobility problem!! Awesome. You are in good hands!!!

First time experience was awesome! Dr. John explained why adjustments were needed and exactly how they worked. I appreciate that he took his time explaining and making sure I understood. After my adjustment I felt an immense amount of pressure gone! I felt like a new person. The next few days at work were great! I wasn't tired or aching like I normally would have been. I have been back a few times since and will continue to go back.

Doc John did an amazing job for my first adjustment ever. He throughly explained the importance of staying on top of your health. He then cut straight into my stiff neck and shoulders. I left feeling on top of the world, and undoubtedly I will come back again!

Been coming here for many many years! Dr John is absolutely amazing and has kept my back feeling great! I highly recommend doing the trifecta here. Go float in the deprivation tank, get a massage and adjustment! It’s a great spa day! I also like booking 4 handed massages! Try this I promise you will thank me!

I met with Dr. Perea a couple days ago for a Chiropractic Adjustment, and it was a wonderful experience!It was my first time getting an adjustment, and I was a little nervous of the process, but Dr. Perea walked me through the science and visuals of getting an adjustment and the benefits. So, by the time we were ready for the adjustment, I felt a lot better and more relaxed.100% recommend, and I will absolutely be returning. Thank you all!

I sit in an office chair 40 hours a week and etting my adjustment here a few times a month really keeps me from daily pain. John is good at what he does, and I always leave feeling better

After my visit I felt so light on my feet. This feeling carried on to the next day. Also my back didn't hurt when I was in the shower. Amazing experience and I know I'll be going back.

I have had 2 adjustments and body has never felt better. My eyesight improved after my first adjustment. Dr. John does a wonderful job. He explains and answers your questions before starting. He has gained another customer for life!

I couldn’t recommend Back In A Flash more!!! I’ve come for almost a dozen adjustments + massages and every time I walk out feeling a million times better than when I walked in.

These guys are absolutely amazing! I would give them 6 stars if I could. Seriously, this is the best massage in Denver. John and Charles were very friendly and professional. I used to have a pain in my upper back and shoulders and after my massage the pain has completely gone away, almost miraculously (yes, only one session). I highly suggest the trifecta, massage, adjustment, and an hour in the float tank. Simply amazing!

Dr. John and the therapists have really helped my body stay out of pain. Highly recommend

Charles (Massage therapist) & Dr. John were absolutely amazing! I went in for a massage and ending up getting the best adjustment of my life too. Great job guys

Been coming here for many many years! Dr John is absolutely amazing and has kept my back feeling great! I highly recommend doing the trifecta here. Go float in the deprivation tank, get a massage and adjustment! It’s a great spa day! I also like booking 4 handed massages! Try this I promise you will thank me!

Simply amazing! Once I got readjusted I feel like everything got brighter! Very clean and professional! Thank you again!

Went and had an adjustment today by Dr. John and to say I feel like a whole new person is an understatement. He did a fantastic job an was great at explaining why adjustments are important.

Dr. John Perea great person walked me through what he would be doing for my back adjustment. Walked out feeling better definitely going back within the next couple of weeks.

Dr. John was awesome knowledgeable, for my first time getting a adjustment made this a comfortable experience I'll definitely will be back every month!!

This place is the best in Denver! After many years of trying many places. Dr John really knows how to take care of everybody, knows his stuff. I highly recommend anyone looking to check him out.

Super easy and convenient chiropractic services that help relieve pain and stress. Would recommend Dr. John if your experiencing back and neck pain.

Dr. John was awesome! He did more in one session than my previous chiropractor ever did!  I WILL be back!

WOOOW. So we've had massages before, but we've never had a Chiropractic adjustment. My back was in a lot of pain- a combo of slipping on a hike and my dog pulled on his leash - my back was on fire. Getting out of bed and bending over was really painful. I somehow dealt with it for a week before searching for help. My boyfriend on the other hand has always complained about lower back pain. We're talking years. He's tried exercises, foam rollers, different contraptions- and hasn't gotten anywhere with it. SO. We both decided it was time to seek some help. THANKFULLY Dr John was able to squeeze us both in this afternoon. I wasn't sure what to expect, but he was extremely informative in explaining how our bodies work, improving nerve flow - all this good stuff I never knew I was missing out on. BOY were we in for an awakening. Our bodies feel amazing. He popped joints we didn't even know we had. We'll be regulars for sure. THANK YOU DR JOHN!!!

I got an amazing massage, fantastic adjustment & relaxed in the float tank! Dr John was amazing at explaining the issues I’ve been having. Annie did a massage with her feet while she held onto bars on the ceiling!

Dr. John is friendly, understanding, great at what he does, and strives to make you feel informed and comfortable. I knew it was needed, but I was nervous to go a chiropractor and he eased my nerves. I am glad I went. I will absolutely be back!

I came here a week ago for the first adjustment by Dr. John. His explanation of what he was doing to adjust the spine and align the nervous system was very enlightening. At first I was taken aback by how short the visit was, but a week later I am even more surprised at how chronic lower back pain and neck stiffness has gone away. I used to crack my neck and back many times throughout the day to relieve the discomfort, but that has gone away since the adjustment. I will be back monthly to maintain this feeling of alignment and pressure relief!

This place is great! I got an adjustment on Tuesday because I couldn't move my neck and I instantly felt better. I also got a massage on Saturday and today I feel amazing! Would highly recommend.

Dr. John was the first chiro I had been to in years. It was a busy Saturday and he still made time to explain the importance of regular adjustments and even took time to explain the way misalignment can cause problems you wouldn't even think of. It made me feel very comfortable knowing he truly believed in the treatment he was providing and wanted everyone to know that they could live healthier pain free lives. I had felt out of whack in my lower back for quite some time and I finally decided enough was enough. After just a couple minutes of consultation Dr. John made adjustments to my ribs, neck, and hips and I felt like a new man in under 20 minutes. With the 1st adjustment special it was only $29, best money I'd spent in a long time. I really appreciate the care shown by Dr. John and I'll be back in a flash for sure.

I have been looking for a new chiropractic clinic for a few months now, and my body made sure I knew it had been too long between visits! For my first visit to back in a flash I decided to get a 60 minute float as well! The soak came first, and it was absolutely an incredible and unforgettable experience. The room was spotless and had every amenity you could need including ear plugs and hairspray! After my amazing soak, I had an adjustment that also did not not disappoint. I have had years of chiropractor experience, but have never met one as invested in his clients as Dr. John. He was open and honest yet professional and effective! I cannot wait to come back in a few days to continue, however if you are in town for a short period of time I highly recommend a float as well as adjustment. You will never forget your experience!!

I had my first massage with Adam this morning and it was awesome. He was able to help me relax and work out all the stress built up from 9-5 work. I highly recommend him if you need a relaxing massage or something a little more deep tissue. I'm going to be hitting the float tank now!

Dr John gave me a good adjustment that gave me instant and lasting relief for my back pain, for a reasonable price without insurance. Great chiropractic in the area

From Downtown Denver to Dream Land I worked all weekend on Xeriscaping my lawn, and by Tuesday I could barely tie my shoes due to lower back pain and sciatica pain. One of my coworkers recommended this chiropractor.  I need some immediate help, so I was worried about scheduling an appointment. However, they quickly intake new patients as walk ins.  28 minutes later, I went from downtown Denver to their office and got my treatment. I immediate felt better, and I'm pumped to be back in the game and off to dream land for the first night in a while.

First time getting adjusted, had some doubts and was a bit nervous but Dr. John took the time to explain the benefits of adjustment and how it could help. I had back pain and some other minor pains and after two days it has all greatly improved. Would highly recommend checking this place out! Also doesn't break the bank which is a plus.

Great adjustment! Didn't need an appointment, just walked in and filled out a form for the first visit. Great prices and no hassling with insurance. Also picked up some high quality organic pain relieving cream for my neck. Very excited to get back for another adjustment!

Anna was wonderful. I woke with neck pain and a day after the massage it is mostly gone. She especially worked on the tight neck and back muscles along with the rest of my body. It was painful in the best way possible. I will definitely be going back to this place.

Super convenient and walk out feeling amazing. Dr. John doesn't try to upsell you. He makes you feel very comfortable and gets the job done. Highly recommend.

Love this place and Dr. John.  I work in healthcare so I need regular adjustments on an crazy schedule.  Easy to get in without an appointment.  Love that it's open past regular business hours. Will definitely be going back on a regular basis!

We were visiting Denver for a soccer tournament. Dr. Perea treated my daughter for her ongoing ankle injuries. He kept her in the game and she felt amazing after her treatment.

Great adjustment by Dr John Perea. It felt great after my first session, now going in for a package deal. Definitely recommended.

Great experience! Easy to schedule online (used the mindbody app), treated myself to a 90 minute CBD massage to address my aches and pains. Annie was wonderful, and I felt very relaxed! She suggested I wait the 15 minutes for Dr. John to come in for an adjustment, as my shoulder and hips were still very tight. He saw me right away, did a quick but thorough assessment, and gave me a great adjustment. Instantly felt relief and loosened up! Bonus: new customers get a discounted rate, and they have affordable membership options! I'll definitely be back!

My back was so destroyed from my car accident and Dr. John really made my body more comfortable! Super professional service and little to no wait time in the lobby!  I also tried the CBD massage and it was the best massage of all time ! They have the largest selection of CBD products I have ever seen! Best in the business !

Came in with severe lower back pain - to the point where I couldn't walk normally. John did an adjustment and made it feel way better. A very clean place with phenomenal customer service. 10/10 and I'll definitely be back. Thanks!

These guys are great! Dr.John is the man! He knows his stuff, is super professional and fun to talk to. He's amazing at what he does. I've never had any issues going in for a visit and even if I have to wait a little bit, they have the most comfortable recliners in the lobby and a TV that's always playing some awesome nature documentary. My neck and back are feeling great and my posture is way better. I think I gained a few inches in height. Thanks Dr. John and crew. You guys rock!

Dr. John is a godsend. He’s very efficient and knows what he is doing clinically. I have been his patient since he opened the practice. And will continue to see him and rely on his services to get my back back in sync in a flash for as long as he is practicing. I’ve sought out other providers.. but had issues returning to them because I would return to them and I felt like 50 first dates... as in they don’t remember my chief complaint... I felt like I would have to explain myself all over again... this is not the case with Dr. John. He knows what’s up and better yet.. he remembers how to remedy the “situation.”

super relaxing verry nice place ,

Great customer service, affordable prices. I am working out of town and tweaked my back. They were able to see me right away and get me threw the day. I plan to go back as recommended. Thanks again Sam

I've been seeing Dr. John for about 3 months now, every other week or so for a quick adjustment during my lunch break. I've honestly always been a bit nervous about chiropractors as they often come across as used car salesmen who have to touch you.Dr. John has always been a straight shooter with me and is always quick, effective and reasonably priced.

Alisha gave me one of the absolute best massages I've ever had! I am a retired athlete, that still lives an active lifestyle and I've struggled with upper back and neck pain and after one session with her I already have noticeable improvements. Back In A Flash isn't just for relaxation and comfort, they really target problems and concerns you express and make the efforts to solve them! I will be making this a monthly self-care practice moving forward. I couldn't recommend them enough!

Great service! Came in due to some lower back pain that's been bothering me for over a month. He told me the importance of getting adjusted especially with how often I workout and after he adjusted me I felt so much better. I will be back, and will get adjusted more often!

Quick, convenient and effective.  Never been popped like I was here.  I like the ability to walk in and quickly get service.

Back in a Flash was exactly what I needed. I love this place! I had a massage by Daisy today and it was one of the best massages I've ever had. She puts in the work for sure. The massage therapists are all amazing though (I haven't had one that I didn't 100% enjoy) and the chiropractor is the only one I'll let adjust me. He's so great! I have recently got into CBD for anxiety and stomach issues. Their selection of CBD is top notch. They have the best products that I can find. I just had a CBD massage too and talk about relaxing  thanks for being amazing!

Went for a massage, very clean and professional. Great massage therapist, Tara. Highly recommend. Look forward to going back for another massage and to try the other services.

When I tell you I had the upmost pain in my feet, hands, and just entire body like you wouldn't believe. I did a couples massage with me and my girlfriend. A cbd infused one at that. We both left lighter, refreshed, & simply amazing. There's no words to describe the feeling. I was so glad we both went for my girls birthday. We were given a tour too! This was more than money could buy. Thank you guys and we will be back trust me!!!!!

Dr John is amazing! His adjustment was strong but gentle. I came in for a triple play, chiropractic adjustment, CBD massage & float tank. I left feeling amazing! The place is HIGH END ITS BEUATIFUL! I was in a room with bars on the ceiling that soon they will be offering CBD massages while holding onto the bars and massage with there feet! I love the CBD selection and the doctor really helped me understand what’s best!

I really enjoyed this place. I personally think that an adjustment must be accompanied by a massage for it to be effective. This is the first place I've found in Denver that offers BOTH. The massage was fantastic and Dr. John did an excellent job with my chiropractic work. I felt like a million bucks walking out of there.

Quick!Effective!Comfortable!Chiropratic adjustments are wlk-in only. At 1st I thought it would be a long wait, but it was very fast.Dr. John, is very efficient and does great work.

I absolutely LOVE this place ! My first visit was a triple threat, a gift from a friend, float tank, chiro, massage... At first I found the float to be very boring... But then I got chiroed after & my whole body adjusted evenly & flawlessly, not my skill, I am usually stiff as a board at the chiro, I will never chiro again without floating first... Highly recommend !

Excellent place, the Doc fixed my back right up. Quite quickly I was aligned and on my way feeling like a million bucks. I will be back again for continued treatments. Overall very happy.

This is my second visit to Back in a Flash. I was referred by a co worker. My 1st massage was with Alisha. Before booking a monthly plan I wanted to give it one more try. Alisha is amazing. She is very in tune with what you need & I am sold. I will definitely be seeing her once a month!

Back in a Flash has a genius business model... walk ins only, $39, no insurance needed for an adjustment. I wish every doctor did this!! Dr. Perea & everyone in the office is super nice. Minimal wait times and effective adjustments... I would recommend them to anyone!

This place really takes care of you. Relaxing atmosphere with a friendly staff and reasonable prices

Great experience ! Clean studio and really friendly and helpful staff. Really enjoyed and will be back!

Great staff

I've been going to this location for almost a year now and they have saved my life as well as my back. The staff is so welcoming, it feels like my second home every visit! They also have a float pool! Coolest most relaxing thing I've ever done. Will do it again. They also provide IV hydration, teeth whitening, massage. They are incredible! I highly suggest giving them a try.

Amazing!!!

I've always been a little uneasy about going to a chiropractor, just something about cracking my neck has always freaked me out.  HOWEVER, since seeing Dr. John twice now, I feel so relieved.  He took the time to really explain why I was experiencing the symptoms I was feeling, and talked to me like a person rather than a dollar sign.  My boyfriend was in the treatment room with me, and our interaction felt very conversational and educational. After my adjustment, I experienced immediate relief of pain and tension, and felt my range of motion improve dramatically.  I get massages and see a soft tissue specialist regularly as well, and my treatments with Dr. John now create the perfect trifecta. I love that there is never a line, no worries about making/missing appointments (all walk-in) and he's FAST!  True to his business name, I was really back in a flash (branding on point).  No insurance = no hassle.  I signed up for a membership and will now see Dr. John twice a month and a can't wait!  I am also interested in the float tank and switching over my massage treatments to his practice as well.

Amazing!!

The facility was super nice! You can play your own music in the tank. Overall a really pleasant experience. If you have a big heavy head like me, l recommend bringing the noodles in with you so you don’t have to get out. Also, I recommend using the earplugs. It’s really nice because you can start music while you’re out and you can turn it on and off while your inside. Back in a flash is a really cool place!

I highly highly recommend Back in a Flash. After my first massage with Alisha, I was hooked! Now I see her regularly and she is one of the best massage therapists that I've ever had. She has an incredible gift for listening to your needs and then working through the areas that really need it and beyond. I have also seen John for a handful of adjustments, which are equally great. You can tell he has a passion for chiropractic health topped off by extensive knowledge that he loves sharing. You won't regret visiting this place.

I highly recommend this practice. Everyone there has always been incredibly friendly and they are so accommodating. Though you can't tell when you enter, the massage room is actually very quiet and relaxing. I've only ever worked with Marilyn but I tell her she has "magic hands". You will not regret coming here! I first visited on a Groupon, but have not stopped coming since.

John saves me on the regular! Even when it’s busy, he’s super quick so you never have to wait long. Lots of other cool services offered as well.

Dr John is excellent! He demonstrates a high level of competence and knowledge. He's the best of all the chiropractors I have had over my 20 years of using many others.

Like other engineers and those who spent too much time behind a computer, I ignored my posture longer than I should have and eventually got myself into a situation where my neck and back were killing me! It was to the point where the muscles in my neck felt like tight rubber bands, radiating pain from my migraines on my forehead to sharp knives running into my shoulder! Yikes! Trying dry needling, physical therapy, and various other "recommended" options, I came to the conclusion I need to try something different that was available on the fly, and did not require appointments weeks in advance. Living near Uptown and Five Points, there are not a lot of walk in chiropractors near me, so I was blessed to find Back In A Flash when I did. Luckily Back In A Flash accepts walk in appointments for chiropractic adjustments, as well as walk in massage therapy appointments based on availability if you are lucky you can even snag a CBD massage therapy session if they aren't booked! Thus, on my way to the Fluid Coffee Bar one day, I was having a killer neck spasm, and decided you know what I am just going to get a massage since Back In A Flash was offering a new patient special of $50 for a 60 minute massage and $29 chiropractic adjustment. Walking in, I was greeted by the best Denver chiropractor, Dr. John who immediately, noticed the neck pain discomfort I was in, and told me first off "Man you need to relax, you are tight throughout your mid back and neck." During the chiropractic adjustment consult, he explained to me the importance of chiropractic adjustments, and making sure "the power is on" in our bodies, as misalignments severely impact our neural pathways. After talking with Dr. John, he also let me know that Back In A Flash offers float tank therapy in their sensory deprivation tank, and offer trigger point massages, which he thought might address some of the knots in my neck and pack. To my surprise, Dr. John let me know that the float tank was currently available, and that if I could try it free of charge to see if that might help my neck. After coming to the conclusion, I probably did need to relax and take a step away from my computer and phone, I decided to try the Back In A Flash wellness playbook of float tank therapy, a trigger point massage, and a chiropractic adjustment, all for $99! I had never floated before, and was surprised how the epsom salts, and the actual act of "floating" could help your muscle relax in that capacity, and tame some of the inflammation. Next, I had a trigger point massage with Marilyn, who did a consult with me prior to starting, and confirmed that my neck muscles were extremely tight, commonly seen as a result of spending too much time on the computer. Marilyn did a great asking me what pressure I was comfortable with, and teaching me how to stretch out certain muscles to relieve the migraines and shoulder pain I had been experiencing. During the massage, I liked that Marilyn customized the massage to what I was looking for help with, and made sure to target the knots in my neck that were giving me issues. Next, I got a chiropractic adjustment with Dr. John. I was very hesitant at first, as I felt the adjustment might do more harm than good. Dr. John did a great job of walking me through the adjustments, and that while there might be some discomfort, I should have some relief within 24-48 hours. It sounded like fireworks on the 4th of July when he adjusted my midback, and neck. I instantly felt relief, like the stars had been realigned, and my neck could actually pivot again. 2 months later, I am a regular at Back In A Flash, and have boughten packages for the chiropractic adjustments, massages, and float tank therapy. Every week, I do the trifecta of chiropractic, massage, and floating, and have never felt better! I have found that regular adjustments and massage have really helped me to develop better posture, and overall feel significantly healthier overall.

SO glad to discover this place...went for massage, loved it. Others there were saying how great the chiropractic service is, and the Float Tank, which we got to see and want to do next visit. Really nice facility, easy access in a nice area, and great people...Highly recommend!

This business is great because it is run by great people. One manager, Chris, was extremely selfless and helped me out immensely after I got in a car accident in the snow. Businesses that genuinely care about the lives of their customers are always better businesses and I am so thankful to have met Chris that night. I highly recommend this because of their excellent service and hospitality.

They have a very nice facility that is welcoming, and the adjustment left me feeling great!! They also offer much more than adjustments.

Don't hesitate, just go. This place is amazing and has changed my life. I don't think people realize how bad they actually feel and how much it is affecting their life and body until they go see a chiropractor and realize how great they feel after. Chiropractors are hard to trust but I've never felt nervous with John - he knows exactly what he's talking about. As long as I live in Denver I will be going here regularly.

I travel for my job extensively throughout Colorado. I always look forward to going to Denver as I consider this place a nice treat! People that sit, drive & work their butts off will appreciate the friendly high quality service! This place understands what customer service means! I so appreciate being able to pop in completely unannounced to get a quick adjustment. I had so much pain when I first started getting Chiro adjustments. I have learned that If I stick with it I feel so much better as a whole! I was going weekly, then biweekly & now I am able to sustain the well feeling results longer so go at minimum every 3-4 weeks if I can. Do yourself a favor & visit this place! Dr. Perea is awesome & so are all the staff! Great massages too.

Recently had a massage with Alisha. She was fantastic! Hit all the parts on my back/neck that were bothering me and was extremely polite and kind. I left feeling 100x better than when I walked in. The atmosphere of this facility is very relaxing and I will definitely be back!

Back in a Flash is the BEST!  I've been going to Dr. John for the past 5 years and he always helps me feel better.  He's helped a lot with relieving my lower back pain, tight neck and headaches.  He and his team are very professional and extremely friendly.  I've sent my employees there for massages and they've had nothing but good things to say about them as well.  I highly recommend Back in a Flash! Next thing on my list to try there is their float tank for relaxation and multiple health benefits!

Dr. John is the best in Denver, walk in uncomfortable and tight and walk out taller and pain free.He's the man.

I love that Dr. John accepts walk-ins! He has helped me out numerous times when I am in pain and other chiropractors are fully booked. I always walk out feeling better than when I came in. Thank you, thank you, thank you!

This place is great! I rarely go to the doctor, chiropractor, use pharmaceuticals, etc. I'm more of a natural remedy kind of guy. I've had a pain / knot in my back, right below my shoulder blade, for almost 6 weeks and nothing I did made it any better. Immediately Dyer leaving here I could tell how much better I felt. I've been to chiropractors before, but I feel like the adjustment here is more assertive and therefore my body was more responsive. I'm planning to come back at least once a month. Thank you!

Great adjustment & the massage was fabulous! Will be going on a regular basis. Everyone was very professional & made me feel at home.

Seriously the best place ever! I started with a nice adjustment, then a facial by Vesper, then a massage, then the float tank & finished with a B-12 shot! It was absolutely perfect! Everyone was amazing from the moment I walked in the door until the moment I walked out. You won’t be disappointed! Make sure to try the float tank it’s a different experience!
