OUR TREATMENTS
I got adjusted by Dr. John for the first time yesterday at Back in a Flash and had a great experience! I came in with shoulder and back pain and Dr. John was attentive to my concerns and did a great job with the adjustment. I feel a noticeable difference today. I was in and out of there in about 20 min., and he even helped me through getting CBD for the first time. I highly recommend Back in a Flash!Danni J.

I have intense lower back up that occassionally flares up. I was in major pain yesterday and was not able to get an appointment anywhere else that was reasonably affordable. Thankfully, Back in a Flash accepts walk ins and is super affordable. I was in and out in 20 minutes, Dr. John did a great job with the adjustment and my back feels 100 times better than it did yesterday. I also like that it's an all in one facility with adjustments, massage therapy and float tank.

Excellent Ambience and Staff. I got a 90 Min. CBD massage with Alisha that had me feeling relief I didn't know was achievable in one session. She addressed and successfully resolved the problem areas I brought to her attention. Can't wait for my next appointment!

Great experience. Walk-in availability was extremely convenient. Dr. Perea explained everything to me before we got started and listened to and addressed all of my ailments, complete with tips for helping my adjustment last and getting the most out of my adjustment. I will definitely be going back for another.

The floatation machine is incredible. Way different than salt lake. Never done it before so was pretty sceptical. Able to suspend effortlessly. Relaxed and completely calmed me. Shut your brain off.

Started going to Back in a Flash when I bought a Groupon for them a few years back. Have continued coming whenever I need an adjustment. Dr. John is fast and efficient. Always feel so much better when I leave. Worth driving the extra distance from my home.

I love Alisha! This was my second massage ever and she took the utmost care of me. Explained everything while it was happening and always checked to see if I was comfortable. My back felt amazing days after. 10/10 Will be going back.

The massage from Alisha was by far the best cross between relaxing and muscular disfunction repair. I chose a deep tissue massage and definitely felt like we made some progress on problem areas. Will be back 100% and highly recommend.

Staff is super friendly, walk ins make it very convenient. This was my first chiropractic experience that I’ve actually benefited from, I felt like a new person walking out. Awesome job, will definitely be going back for any future adjustments!!

My first time getting an adjustment and I have to say, it was amazing. Dr. John explained to me what he was going to do and why, and the way he explained it made sense in a really easy to understand way. That made me feel good going in, and then when he started, i felt an instant relief. It was truly amazing. I didn't realize how much pain I was dealing with until now. I will be taking better care of myself and coming in to get regular adjustments from now on. I highly recommend this place. Thanks Dr. John

Prior to this visit I hadn't seen a chiropractor before, so I had zero idea what to expect. With a name like Back in a Flash, I could only assume that the process was quick. Which it was, but what I mostly appreciated about this visit was, how in depth my chiropractor was about the whole process and what was going on in my body. He really helped me understand how my problem was affecting my body, and what he was going to do to relieve the pain. After a quick and in depth rundown of what was going on, back in a flash happened. It was awesome. I strongly consider checking this place out.

What an awesome practice!!! I came in with traumatic pain. A combo of massage and adjustment was just the cure my body needed. Dr John was amazing. Explained everything before we got started and made me feel so comfortable. Adam is one of the best massage therapist I’ve seen. I will without a doubt be back to continue to heal my body.

I walked through the doors in severe neck pain. It was my last hope before going to the doctors office. After explaining everything in great detail, he popped my back and neck and I instantly felt relief. I have had neck problems for over 8 years. I plan to go back in a week and am wanting to make it a part of my monthly routine. I would highly recommend Back in a Flash to anyone! Fantastic results.

Decided to go there after learning several of my friends and coworkers have frequented this business. Dr. John gave a thorough explanation of why it's good to keep with regular adjustments. I had a really effective adjustment and then soaked in a float tank for an hour after. They offer very reasonable special introductory prices as well as reasonably priced packages. Next time I think I'll try a massage before the adjustment and maybe soak afterwards. It was my first time soaking so it takes a bit of getting used to but I think it'll feel more natural the second time around now that I know what I'm doing.

Great place! I just visited for my first float session and everything about the experience was so wonderful. Super easy to book online, friendly and helpful staff when I arrived, and nice clean space. I will absolutely be back again!!

Dr. John is excellent. I was in great pain when I came to see him. After my first session, I experienced same day relief. I now go twice a month which helps me with my pain and ensuring my body is in alignment. I highly recommend Dr. John!

This is the first chiropractors office I have ever visited and they have always made me feel comfortable. At my first visit Dr. John used a spine model to explain to me the benefits of getting regular adjustments. The location is very convenient to my home and employer and the price is fair. I don’t visit as often as they tell me I should but also never feel pressured to come in more often. I recently visited for a massage as well and am excited to try the float tank and their other services.

Walked in for a first time adjustment and was seen in 10 minutes. I completed my forms and was adjusted shortly after. Dr. John Parea and staff were friendly, professional, and helpful. I was long over due for an adjustment and I came in seeking relief from stiffness and discomfort due to a long week of traveling. I look forward to returning for my future adjustments.
Reychel Saflor
22:25 07 Feb 19
It was amazing! I learned so much as he took the time to explain everything! I feel so much better after the adjustment. Will definitely be back again!!

I started seeing Alisha at Back in a Flash a few months ago for massage therapy, and she’s helped me make a big improvement in the pain and tension that brought me in. Her warmth and knowledge made it easy to connect from the beginning, and she easily identifies my causes of discomfort. On top of everything, she’s shown me stretches I can do at home and made me mindful of my posture as ways to prevent pain. I really appreciate that she goes the extra mile, and I always walk out feeling great. Thank you, Back in a Flash and Alisha!
Hayley Brown

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 have been going to Back in a Flash for a few months and it's been an all around great experience. I've mostly gone for chiropractic adjustments and never have to wait more than 5 minutes to be seen. The staff is friendly and the waiting area has super comfy loungers. I've had a few massages that have also been good and very relaxing. I'm looking forward to trying some of the other services offered, like the float tank.

I’ve been here a few times and I’ve had great experiences . Yesterday, I pulled up the iPhone measuring app and found out I was -4 degrees (tested multiple times on different surfaces, re-leveling each time). I hadn’t been in to see Dr. John in a month or so. I went to see Dr. John today and re-measured afterwards, and what do you know, I was at 0 degrees. And that, my friends, is what warrants a special google review. 👍

Awesome place for massage! Girlfriend and I came here, got couples massage with Alisha and Emma, highly recommend. Also saw the float tank and heard it is also amazing, so planning to try that next time as well!

This was my very first Chiropractor experience. Doctor John Perea is great! He made really help with my back issues. I highly recommend this place. i cant wait to start coming here regularly. Pricing is very reasonable!! I am very Satisfied with my visit and the friendly environment Alisha was so friendly and welcoming!

I fell on Ice today walking to work and slipped my L5. All of my chiropractic offices that take my insurance would not accept me today and I was in so much pain and had to leave work. I was able to be realigned without an appointment and was able to have a treatment plan set up right away with Dr.John Perea. my last Dr. moved out of Colorado and I was worried about my options during this emergency. I highly recommend "Back In a Flash" they worked a miracle for me today and for an amazing price that was affordable. Thank you so much

This is the best place to go if you need an affordable quick readjustment right away! I was so pleased I was able to call ahead and let them know I was walking over and they put me right in and sent me on my way! DAY MADE!!

00:47 08 Nov 18
2 90 minute floats later and I’m definitely figuring this out! This is a really nice facility to do so, everything you need is in the same room as the tank so if at any time you feel like you need to shower, dry your face, apply Vaseline to places you missed, new ear plugs..... it’s all right there! Staff explains things well if you need and there’s lots of good music queued up on the iPad if you like some subtle beats to refocus on!

Back in a flash is awesome! The walk-in appointments are convenient and the plans are a good deal as well. I love the attentiveness I receive and appreciate that John takes time to ask about old injuries. All around a good experience.

Long time chiro user. 1st visit with Back in a Flash. Great experience. Immediately meet with Dr. John and had a natural connection. 1st adjustment was through and professional. Lisa (office assistant) spent time showing the facility and explaining fee structures. Looking forward to my next visit and interested in the Float Theraphy! 5 Stars....

Dr. John is amazing! Not only is he great at adjusting, but he always makes sure to educate on what he is adjusting and why. He's my go to guy after my games and after long with weeks. A definitely recommend!

Dr. John did a great job on my first visit. I've had back and neck pain for awhile now and he went into great detail in how to help fix the issue on my own while also giving me a great adjustment. I fell great and will be back again!

I walked in for an adjustment with Dr. John adjustment yesterday. He was very knowledgeable and informative. My visit was efficient and incredibly effective. I have little prior experience with chiropractors or adjustments because I've been generally skeptical about the safety of adjustments but Dr. John was amazing. I will definitely be mixing him into my rotation of bodyworkers.
Kate Evers
16:58 20 Sep 18
I had never visited a chiropractor in my life and I was skeptical to visit one. But my acute lower back pain made me desperate to visit one. Dr.John was seeing walk ins and I am so glad I walked in. He sounded knowledgeable and explained to me very thoroughly how it works. He made some quick adjustments on my spine and I felt better instantly. "My pain is gone and I feel better than I have in years". I followed it with a 60 minute massage from Alisha and it was a wonderful experience. She was very methodical and my back felt rejuvenated after the massage. I am going to see them again.

Wow. I happened to be in Denver, Co that day on business & stumbled upon this place. I was in so much pain & they took me in as a walk-in for an adjustment. That in itself is impressive! That was one of the best adjustments I have ever had. Dr. John really knows his stuff. I feel at least 60% better with just one session which is amazing given how I have ignored my problem & let it go chronic. I was truly amazed at his skill & professionalism with which this facility operates. I can hardly wait for my next adjustment & a massage. I don’t live in Denver but will drive miles just to get their services. Alisha was a one of a kind greeter, so sweet & caring. When you are in pain & miserable, this place will take good care of you! You must see for yourself!

I am so glad I went ahead and did business with this place. Dr John was amazing! He explained it to me very well, he was fast, made it as gentle as possible and made me feel very amazing afterwards! I would definitely be recommending people here and will be back myself! The ladies at the front desk were awesome as well, very friendly and helpful. I was terrified to come to a place like this but Back in a Flash made it an awesome experience for me!
Arriana Romero
20:21 08 Sep 18
I've been coming to Dr. John for 6 months for adjustments and haven't felt this good consistently in a really long time! He's knowledgeable and will take the time to talk with you about what's going on with your back and how to get it right. They offer a great monthly membership, too, which equates to around $20/ session!
Dana Morano
16:28 30 Aug 18
I threw my back out unexpectedly and Dr. John fixed me right up as a last minute walk in. I will never go to any other chiropractor again! He's the absolute best and I highly recommend getting an adjustment from him! I honestly can't wait to go again.

ADAM is an amazing masseuse! Thank goodness I found him! He listens to your needs and has an exceptional professional touch that makes you feel like you really got your money's worth. The room is clean and relaxing. He is always punctual and easy to get in touch with. I highly recommend him!

I called one Saturday afternoon, I had the most excruciating neck pain, I was even struggling to swallow. I called 30 mins before closing time, that day they were going to close even earlier. I think they heard my voice of desperation, they said they would wait until I would show up. He cracked my neck, and immediately tears started to run down my face, it was a sense of relief but very painful. He adjusted the other side, and then let me lay there with ice on my neck. John, took the time to help me, I will forever be grateful. He explained to me that I sprained my neck, and is now helping me with issues that i have in my neck. I am now a loyal customer and have purchased the monthly adjustments just because I trust him and can tell that he definitely cares to help.

Dr. John is by far THE BEST CHIROPRACTOR that I have seen since my injuries & associated problems started 15+ years ago. I have seen a countless number of other "so-called" chiropractors, but Dr. John Perea is definitely in a league of his own!Suffering from sciatica and a herniation at L5-S1, my medical doctor initially said that I would likely need surgery, but my orthopedic doctor recommended that I try chiropractic adjustments and massage therapy first.Well that's where the last 15 years of looking for a good chiropractor have left me - STILL needing treatment. It wasn't until I met with Dr. John & Marilyn (massage therapist) that I realized what a chiropractic office SHOULD be like & WHAT he should do to address my sciatic and issues stemming from a herniation at L5-S1.Dr. John always ensures that his patients feel welcomed, at ease and comfortable with both himself as well as his procedures. He combines all of the above with a perfect mix of professionalism & empathy making it a welcomed "joy" rather than a chore to go to a chiropractic appointment, not to mention the awesome trigger point massages I get from Marilyn.Lastly, I am almost always pain-free until my next appointment, and one very specific problem area that has consistently plagued me over the last 15 years, in a matter of only a couple visits, has COMPLETELY HEALED in that area!I would recommend Dr. John over anyone, especially all of the other Denver Chiropractors hands down!! It doesn't matter if you live next door in Downtown Denver or 200 miles away - you MUST SEE HIM, you'll be well-pleased with your choice in chiropractic care!

I absolutely love coming to back in a Flash Chiropractic & Massage. I always receive the best customer service. Dr. John is the best chiropractor that I've personally experienced. The massage therapist do amazing massages. I have also experienced the float therapy deprivation tank, love it! Very happy with Back in a Flash Chiropractic massage and will continue to get my services here. You should come check it out!

I was referred to Dr John by a friend. My son had extreme lower back pain when we went in. After Dr John gave him his first adjustment, he walked out feeling almost 100% better. We purchased a very affordable package & look forward to further adjustments. Nice office, friendly staff & great chiropractor care!

This place is amazing. I would recommend to my friends and family. I just gotten back from Vacation and was hurting from my lower back. I couldn’t last sitting or standing. I was in pain. I looked them up on line read some reviews like this one and decided to give them a try. This was my first visit to a Chiropractic doctor. They accept walking’s which is a plus. The doctor was very friendly and explained everything. He adjusted my back and when I got up I felt amazing like seriously 10 years younger right away. My pain when away! Give them a try you would not be disappointed. They do massages too..

This was the first chiropractor I have ever tried and I am so happy I did. For the first time in over a year I can sleep thru a whole night because of the amazing results I got from doctor John. If your even just slightly considering getting an adjustment I would go see the miracle worker doctor John. Not to mention I can get thru a whole day of working and driving without any issues it is amazing.

This is a wonderful place! So many good things under one roof. I’ve been getting massage from Adam for over a year now. I have to say Adam is phenomenal! Best massage therapist I’ve ever had. Dr John is just as good for your chiropractic needs.This office is mellow, so no need to feel stressed or overwhelmed when you walk in to this wonderful place!

The fact that they do walk ins was amazing. I came in after a long day for an adjustment (my first one ever) and Dr P made it so easy to understand the importance of the adjustment before we started. Then, me being pregnant he was very careful with my body & made sure that he explained as he was going. Such a genuine and quick & easy place and people. In and out feeling better posture and alignment right away.

I have been having bad headaches for some time now. After a few visits with Dr. John I have had major improvements. I am able to sleep better and haven't had to take pain meds to cope with the pounding. Give them a try, I did and I am so thankful for going.

Daisy was intuitive, caring, and kind. I would recommend anyone looking to relieve muscular tension. She knew what specific spots to massage and the right kind of pressure, which is hard to find.

I was amazed how many services they offer under one roof, I started with float tank 1.5 hours, right into an hour massage, then got chiropractic. All were superb, clean & affordable. As I was checking out noticed 3 more spa type services I didn’t know were in the same office. Referred a girlfriend who went in the next day for all the same with same results👍🏻. Yes this place has it figured out.

I went in 20 minutes after reading some reviews and scoping out the website. I was barely able to walk myself in with a pain level of 9, and less than 30 minutes later I was waking out feeling maybe a 1 in terms of levels of pain that he had warned me would most likely happen since my body was adjusting and explained that with some at home care should go down to a zero. Dr. Perea was friendly, efficient and highly skilled. I would recommend him to anyone looking for a trusted expert. Looking forward to future appointments.
