My partner had a bad fall while snowboarding and was sore for a few days. He thought the pain would go away but when it was over 5 days wincing with pain, he decided to find a chiropractor. It was the day after Christmas, many businesses were closed and by the time he thought to call, it was late in the afternoon. Dr. John said he they closed in 15 and we got there 10 minutes later and he graciously stayed open for both of us to get adjustments. I thought he was already working overtime, so he would skip the pleasantries, but he sat us both down and gave us a long and detailed explanation of how he approaches chiropractic services and how our bodies work. The adjustments on both of us were great and he took time to explain each move as he did them. I’ve had minor back pain for 3 years and have seen 5 different chiropractors in 3 states (I travel a lot for work) — Dr. John is by far the least sketchy and most straightforward chiropractor with immediate results. Some chiropractors immediately try to tack on exercise equipment, traction belts, vitamins for joint health etc. While some of these things may work, there was no upsell here — Dr. John just focused on a really great and effective adjustment.
The adjustment costs $ 29 with no need for insurance — affordable and easy! Don’t be like me and wait months for adjustments, I should go for regular maintenance and if I lived here I would definitely see Dr. John all the time.

Seen Doc John 3 or 4 times now. Couldn’t ask for a better chiropractor. You walk right in and pay $ 29 and it takes about 15 – 20 minutes. I’ve never had to wait more than 5 minutes to see him. He’s a really good doc and I’ve felt much better Everytime I’ve left from getting an adjustment. Will always go and see him If I need a chiropractor. Highly recommend!

I’ve been going to Back in a Flash since almost it’s opening in 2012. I was a little skeptical about a walk-​in, membership oriented chiropractor but when I discovered how talented Dr. John Perea is, I was thrilled to be able to get the best treatment in Denver and at a very good value. My sister is an excellent chiropractor in Illinois and Dr. Perea is the only chiropractor I’ve been to in 25 year other than my sister who will do extremities. He’s always gentle but confident enough to get my lumbar rolls and neck adjustments to move big time. If you’ve ever has a so-​so or negative chiropractor experience, chances are it was just an unskilled doctor. Give this guy a try. He helps me with body alignment and respiratory issues. Can’t imaging life without him. If Back in a Flash ever replaced him (unless they moved him to Boulder Co. where I live) I wouldn’t go there. He’s worth driving 40 minutes for!!!

I have never been to a chiropractor before, but I work on my feet and after developing aches and pains I figured it was worth a try. I am so glad I found Dr. John! He took the time to explain what he was doing and why, and I walked away feeling balanced and energized. I will definitely be back for monthly adjustments.

In Denver for 2 days. Walking back from yoga and just passed by this place seeing it was $ 29 for an adjustment. It seemed too good to be true. No appointment, no insurance fuss. I haven’t been to the chiropractor in 10 years and as a pharmacist, my ear is usually glued to my shoulder by a phone. I walked out feeling like a million bucks. I do yoga religiously and thought that handled any alignment issues, but in truth you really need adjustments. I’m definitely going back tomorrow.

I’ve had scoliosis most my life, I’ve seen a ton of chiropractors since I was 15 to help ease the pain. I found one in San Diego that was great, but it wasn’t until I met Dr John @ this location that I finally felt like I found the one! If I could see him every day I would! Highly recommend this place for all your chiropractor needs

I haven’t been back to Dr. John in almost 2 years. As soon as he saw me, he recognized me. That’s what I would call a personable business owner! I went in because of my sciatica, I was limping and couldn’t stand up all the way, and I felt pain all the way down my leg and into my foot… I went to the back and he did the adjustment, and I was out of there in 20 minutes, if that. If you want a caring, laid back, very knowledgeable chiro, do yourself a favor and go see Dr. John Perea.

I’ve been going to Dr. Perea for over a year and he’s fantastic. He’s super friendly and his work is great, prices are reasonable, and the hours/​walk in availability are perfect with my work schedule. I have a monthly membership, and always leave feeling 10x better.

I’ve tried a few different Chiropractic places around downtown and this is my favorite. Dr. Perea is very cool and laid back, and I didn’t feel any of the sales pressure that intrinsically seems to go along with most private practices. I saw a different Chiropractor a couple of years before and he was always pushing more visits on me; none of that here! Also, from the standpoint of affordability, the monthly 4 visit plan can’t be beat. It is a good location in Uptown Square and is easy to find on street parking or walk from downtown. My only complaint is that I wish that adjustments would roll over from month to month if you don’t use them; currently, if you don’t use them, you lose them. That’s not too big a deal, though, for the value you get here!

Dr Perea was awesome! My fiancé & I were in town visiting family. He hurt his neck & needed to be seem right away. Dr Perea stayed open later just so we could make it in time. My fiancé saw him one more time before we left & I even got an adjustment. Dr Pere did an amazing job. My fiancées pain was gone & we both felt a million times better. I would highly recommend them! Cheap walk in rates & amazing monthly memberships. If I lived in Denver I would make him my regular Chiro!

Has anyone seen this guy in the last week or so? He took money out of my account and I haven’t even seen him for 2 months or more. I’ve tried to call and left several messages but he doesn’t answer or has he tried to call me back. Any news of his where a bouts?

I’ve been going to Dr. Perea for about 9 months now and I am very happy with the services. He is a friendly and trusting chiropractor. Being able to drop in without an appointment is a huge perk! The prices are very reasonable and offers options to be able to afford regular treatment which is hard to find. He does an amazing job every time and really works out those extra kinks. I can’t imagine going to anyone else.

As I prepare to descend into the depths of bar exam hell, I decided to scope out all my coping tools in the Uptown area. As expected, the first week of bar prep has literally been a pain in the neck. I just couldn’t sit and focus on lectures anymore. So I grabbed my bag and followed the trusty Unilocal app down the street.
I was a little unsure of what to expect because I’ve never really been adjusted before, but damn. Dr. Perea is not only very knowledgeable, he’s very laid back and relaxed. You can’t help but feel the same.
I’m pretty sure we were playing a wide range of notes with my cervical and thoracic vertebrae. I’ve never heard them like that before. In fact, I’ve never heard them at all. That was my biggest problem. So here’s to less of a symphony from here on out.
Definitely making use of the monthly package — which is a steal. Do yourself and your body a favor, and get a tune-​up here. After years of muscle relaxants and unnecessary doses of Advil, you’ll no doubt thank yourself later.

Don’t let the pun scare you, this place is legit.
I think the my favorite thing about this place is how convenient it is: no appointment needed, scan in upon arrival, monthly membership so no on the spot payment.
Everything that’s a hassle about going to the doctors is non existent here. You walk in, get adjusted, walk out. Takes no time at all and you can come in at your own convenience.
Th adjustments are good and thorough. My neck was killing me to the point I could barely get through the day. Went in for an adjustment, followed the Drs care instructions and was better within 48 hours. Have been in since just for tightness and lower back issues since and feel great within 24 hours of each visit.
Would recommend to anyone.

This guy is great. He’s super friendly and there’s never a line. He’s pretty quick. You’re in and out in like 15 – 20 minutes, max. Payment is easy — if you sign up for the monthly payment, you get a little card or can just give him your information. It’s not a monthly subscription in that it doesn’t automatically renew. You just pay for the next 4 weeks the first time you stop by in any given month.
I had never gone to a chiropractor before so I was nervous but in a lot of pain when I went to see him. He was nice, gentle, explained what he was going to do, and made me feel A LOT better. It’s also incredibly cheap. I get the impression this place is fairly new so it may get busier as time goes on.

I am so glad to have found a reliable chiropractor who offers such reasonable price plans. This is a genius idea: for $ 49 per month, you can drop in as many times as you like, with no appointment necessary. (Actually, I think the place works entirely on a drop-​in basis, regardless of whether you are paying the monthly rate or paying by the visit.) You get adjusted and get on your way in 15 minutes or so.
Dr. Perea is a really nice guy and you can trust him with your bones. After going regularly for a few months (something I could never afford on a per-​appointment basis), my back pain was considerably reduced. He is enthusiastic, skilled, and willing to explain what he’s doing.
I wondered initially if I’d end up waiting in line behind several other people, but that never seems to happen. If you need chiropractic help but don’t have the time and money for regular lengthy sessions, this is a brilliant solution.

Just moved to Denver and needed an awesome chiropractor. This place is only a block from where I live so decided to give it a try. Walked in with no appointment; had an awesome initial review with Dr Perea (very thorough). Adjustment was quick, efficient, and AMAZING!
Love their promotions ($ 49 a month for 4 adjustments — are you kidding me!!! AWESOME!!) — and love the key chain idea.
I’ve been to MANY chiropractors over the years. Dr Perea is great and I will definitely be going back consistently. HIGHLY RECOMMENDED!

I live right around the corner and stopped in to Back In A Flash when I was walking my dog (bring your pup, they are dog-​friendly!). I have never had chiropractic work done but based on friends’ recommendations I decided to try it since they were giving out free adjustments on their first day open — lucky me! Overall, I was very pleased:
The staff was very friendly and explained their mission: to provide quick, low-​cost chiropractic without any snobby pretense. They have super-​affordable adjustment rates ($ 29 for a walk in) and even better rates for monthly packages ($ 49 for 4 adjustments/​month).
It was my first adjustment so I don’t have much context for the review but it felt great! I had no idea my body has so many parts that go ‘POP’! Upon getting up, I just felt rejuvenated and like I could move a bit more freely. I even reached down and touched my toes! That night, I cranked a home run in my softball game and now I’m a believer!
Clean + Friendly + Affordable + Effective = Home Run (literally & figuratively)
