I can’t recommend Ian enough as a physical therapist! He helped me recover from both a neck/shoulder injury and a knee injury with a thoughtful, individualized approach. Our sessions included thorough assessments, targeted dry needling, and exercises that were exactly what I needed to heal and regain strength. Beyond his work as a PT, Ian is also a member of our gym, Boulder CrossFit, and has been an incredible resource for our community. He teaches seminars that have been invaluable to both our members and coaches, providing warm-ups and techniques that keep everyone strong, healthy, and moving well. His expertise, attention to detail, and genuine care for his patients make him truly exceptional. If you’re looking for a knowledgeable and effective PT, Ian is the best!

I was doing deadlifts and back squats on a Smith Machine. Because of the Smith Machine's lack of mobility, I injured my lower back and L glute. After several days of increasing pain and decreasing amount of my able to walk pain free, I set-up an appointment with Mend. Ian did a thorough history and evaluation, and recommended dry needling on the very sore L glute. I was a little apprehensive about the dry needling, but I didn't fell the insertion and the electrical stimuation was not painful, just a weird sensation. Ian then demonstrated 2 exercises I should do. I walked out of the appoint very much relieved of the most sever pain. Over the next 3 days there was improvement. My follow-up appt w Ian moved me further along the road to recovery. More testing of my leg strength and exercises, I walkout able to walk w/o pain. Ian did an extraordinary job to rehabbing me back to my active life.

Ian Nay is the BEST!!! As a CrossFit coach and athlete finding a PT that doesn’t tell you to stop everything you’re doing and you’re messing up your body is really hard to find! Ian helped me work through my injuries and made me an even stronger athlete with now no shoulder pain!!! And I didn’t have to stop doing what made me happy (CrossFit)!! Knowing Ian is an active crossfitter himself he really understood what I wanted to accomplish and understood the benefits of doing CrossFit!! Enough said Ian absolutely ROCKS!!!

I had a super positive experience at Mend Physical Therapy. Highly recommend Dr. Ian Nay whose approach is personalized and professional. His prescribed PT tackled my nagging hip discomfort head on, and in just a few weeks I'm feeling entirely pain free.

Dr. Nay did a fantastic job working through a sport injury for my 15 year old daughter. His treatment plan was easy to follow and allowed for a successful rehab back to being pain free in a short amount of time. I will be recommending Dr. Nay to anyone in need of physical therapy!

I’ve been battling with a nagging ankle injury for the past two or so years. I didn’t think I would ever recover and somewhat lost hope of being active again. I made an appointment with Dr. Ian Nay, not only is he well educated and informative but also passionate about what he does when treating his patients. I’m about 4 weeks into my treatment and couldn’t believe the progress I’ve made so far. We have a ways to go to still, but I’m ecstatic to have what feels like a part of my life that has been missing back. I cannot recommend Ian and this facility enough!

The PT’s at MEND are absolutely wonderful and I would recommend them for any physical ailments or injuries. I’ve been seeing Robert for different things I’ve dealt with over the last year + and he’s helped me navigate through injuries, given me actionable advice and exercises, and helped educate me on what it is that’s going on. I cannot speak highly enough about this clinic and the way that they serve the Boulder community!
