Dr. Zac and the practice at Cohen Health and Performance have legitimatley changed my life. Prior to joining, I had recurrent joint issues that seemed to affect every joint - knee problems, wrist problems, ankle problems. I worked out regularly, but every exercise seemed precarious, like it might create a new injury. Add to that two high-velocity children! Zac identified my underlying biomechanical issues, and has given me the exercises to address them. What's more, he also has me on a consistently-varied, fun program that builds a solid foundation, gets me strong, and helps me avoid any new injuries. He regularly progresses my exercises, and constantly finds new ones to help me solve any additional problems (and build muscle) I'm stronger, more fit, and more stable than I've been in decades - maybe ever. Issues that I thought I'd live with forever are essentially gone. Thank you so much, Zac, and the entire practice!
