Mitch and Zach are top notch when it comes to all aspects of fitness. I regularly seek advice from them and am always impressed with their depth of knowledge and professionalism. If you are thinking of reaching out to it. They are both down to earth and ready to help no matter where you are in your fitness journey.

I was refered to Zach with 3 surgeries under my belt and fresh out of an major bone transplant - all on my left knee - so it's safe to say I came in with a ton of questions and concerns. After my first session I knew I was in the right place! Zach's supreme knowledge on recovery therapy and passion to help people like me with serious/chronic sports injury was clear from the start and I immediately felt i was in good hands. Geeking out over sports and cutting edge physical therapy tools only helped make the rehab process more fun not to mention the really creative and challenging recovery workouts to get me back to form. After a few months of intense rehab I'm happy to say I'm on the fast road to recovery and should be back to league ball by end of the year. Thanks for all yur help bro! Couldnt have done this without your hell. Keep up the great work.

I had the opportunity to work with Zach on my right knee after a meniscus surgery and a previous ACL surgery on the same knee. He was super attentive and exactly what I was looking for. He has a large variety of exercices in his bag, I felt like I had an offseason pro program! That was awesome. I will come back for more sessions for sure! Thanks Zach.
