My wife and I started training 2x weekly with Mitch and the improvement in fitness and strength has been tremendous. It’s a very thoughtful, practical, customized program with just the right amount of pushing. I also started PT work with Zach for an unrelated back injury and it’s great that they can tailor the workout program in partnership with my PT work.


HIDEF is AMAZING! I've been getting treatment from Dr. Zach for a couple of months. I injured my lower back, keens and, shoulders badly from a bad fall in Nov last year. Zach is extremely knowledgeable, patient and practical. He customizes my treatment plan and even connects with my personal trainer regarding my condition for workouts. With his help, I'm fully recovered and back to the gym compared to not being able to walk a while ago. I plan to continue seeing him for the recovery/treatment after lifting even I don't have injury anymore.


Mitch, Katie, and Zach are a dream team! I've had nagging imbalances and posture issues that have been quite painful, and I've been treated for in various ways for YEARS. I have improved more in just a few weeks than I ever have, and I am completely blown away. Mitch's workouts are amazingly effective, and I never feel over-exerted or strained. But he's pushed me in the best way and showed me I could do things that I would've never attempted. I trust his opinion and expertise completely. I've probably been a problem client for Katie, who's been helping me with nutrition, but she's been SO INCREDIBLE at reframing my perspective, and showing me how to actually live with the changes I want to make. I just started Zach's treatment after 1 eval and am so pumped and excited and already feel better. With the 3 of them, I've felt stronger, healthier, and more balanced than I thought possible. Phenomenal!
