I herniated two discs in my lumbar spine about 11 years ago, and periodically battle symptoms from it. Ive seen a number of chiropractors & therapists over the years; Dr Neff stands out as the best that I have encountered. The muscular activation dimension of his training has had a big and lasting impact on my health. He is extremely passionate about his work, and brings a great functional and athletic perspective.

Dr. Garrett Neff and his team are top-notch healers and fitness experts. This is a functional sports medicine and chiropractic clinic designed to meet individual needs and empower a community. If you want to improve your performance or simply feel better and move better in your life, this is the place to go. They are some of the nicest, helpful practitioners youll meet!

Dr. Neff is the best in the business. He treated my sprained ankle multiple times during peak ski season. Got me back out on the slopes faster than I expected. Hes also done a wonderful job treating my girlfriends back. Id highly recommend trying him out. His treatments and philosophy go way beyond what you would expect from a traditional chiropractor.

I came across Dr. Garrett Neff while searching for alternative options after giving up on standard chiropractic adjustments. His AMIT approach found that the rib pain I was experiencing was not actually rib pain, but was due to lack of muscle activation as well as a compressed nerve in my neck. Within 3 sessions I no longer had any pain and was even able to move my shoulder better than I had in the last year. I am now able to compete at a higher level in Crossfit than I ever have before and know that a quality, quick fix is just an appointment away if needed!

Truebility Performance is amazing! I have been seeing a chiropractor regularly for 18 years, mostly for the same issues/symptoms. When we moved to Colorado 2 years ago, I found Dr. Garrett and he has changed my life. I originally saw him with the same symptoms and I found instant relief from our session. What was different, however, is he explained what was happening and gave me exercises and mobility so I could work on my issues outside his office - and they worked wonderfully. I no longer have those same issues or symptoms, so relieving!!! I started CrossFit in January and I have been seeing him regularly to keep my body moving the way it should. Ive also seen Matt Nasta for massage and it was fantastic. It was not your typical spa massage, but I left feeling amazing. He also explained some of the trouble areas he found and gave suggestions on how to improve them from home. I am convinced you all have been crucial in my CrossFit success and my overall well being.Dr. Garrett has also successfully treated husband, my 1 year old son (for fussiness and trouble sleeping) and my 7 year old gymnast (to identify and work on movement/mobility issues).These guys are friendly and knowledgeable, the atmosphere at the office is welcoming and laid back, and the results speak for themselves. I cannot say enough about Truebility!

I cannot speak highly enough of the team at Truebility Performance Clinic. As someone who has been pretty active and hard on my body most of my life, I have literally seen countless wellness practitioners (chiropractors, PTs, massage therapists, acupuncturists, orthopedists, etc...)throughout the years, and none of them even come close to the level of expertise, skill, and overall quality of care I have received at Truebility.I currently do Crossfit at least 5 x week in addition to lifting and other metabolic training, and the only reason that I am able to do these things that I love so much is because of this team. Garrett, Katy, and Matt collaborate to ensure that each patient receives the full depth and breadth of knowledge that they each bring to the table, treating all aspects of what may be causing problems instead of just trying for the quick fix by putting a band-aid on the symptoms. Each practitioner is adept at various modalities, and together they bring so much to the table that it is truly extraordinary. They have helped me work through intense knee pain/joint stiffness, chronic shin splints, significant shoulder limitations (impingement and tendinitis), chronic upper back pain associated with a separated rib, and have even helped alleviate pain from a torn labrum in my hip.Aside from the exceedingly high level of skill and elite level of knowledge found at Truebility, the practitioners are all super friendly, and they somehow make the visits to the clinic quite enjoyable despite the sometimes painful procedures. I often find myself laughing hysterically while simultaneously wanting to cry and punch somebody, and in the world of sports performance rehabilitation, I consider that a huge win. It is abundantly clear that the practitioners love what they do and are truly there to serve their clients. And, of course, a review of Truebility wouldnt be complete without mentioning Leonard, the adorable little poodle, who greets everyone with one ear up and an adorable underbite. He will even get on the table with you if you need extra support :-).In the active world, and in Boulder, especially, we tend to accept aches and pains as a way of life - the price we pay for staying active, but it does not have to be that way! Go see the folks at Truebility!

Amazing!!! Dr. Garrett Neff worked on me after the Lory XTerra and it was incredible. He worked on my neck and knee- he is really incredible. He explains what he is doing and somehow knows exactly how/where to work on me.Thank you so much Dr. Neff for helping me after my XTerra and before my half ironman! You rock big time.

Hands down, the best chiropractor in Boulder.
