We Help Get You Back in the Game

At Cohen Health and Performance we help injured athletes get back in the game.

Our mission is to enhance the lives of individuals who desire to live an active lifestyle by providing elite level physical therapy and performance training for continued health and wellness.

This is not your run of the mill physical therapy practice! We treat you as an individual, rather than splitting our attention between multiple patients at once. We utilize our beautiful physical therapy clinic and state of the art sports performance facility to help you get better, and in less visits then the standard rehab setting!

If you are an athlete that is in pain, injured or limited from performing at your highest level, we are here to help you!

Regardless of their exercise preference, kettlebell swings often find their way into the regimen. This is for good reason as the kettlebell swing is a great exercise. However, like all exercises, when performed improperly it can result in discomfort.

Client Testimonials

Jamel Richardson Image

"After playing in the CFL over 10 years I tore my ACL/LCL. I was concerned about how I would get into the best shape possible, and I turned to Zac for rehabilitation. Zac by far was the best PT/trainer I've ever worked with and pushed me to the limit. Zac challenged me by advancing me through innovative training allowing me to return at the highest level I could imagine."

Jamel Richardson
Former NFL and current CFL football player, Grey Cup MVP

"I worked with Zac after my second ACL repair. He allowed me to get back on the field and playing better then I was prior to my injury and sooner then I ever thought possible. I was very nervous to return to play since this was my second ACL tear but he made me feel so confident due to his expertise and dedication to his patients. I wish I had known about Zac before my first injury!"

"I tried to work with a 'big chain' PT group following a lower back surgery earlier this year. My time with them felt rushed and transactional and I never fully invested in the process. In contrast, Dr. Cohen is a fantastic PT and really takes the time to create and explain specific plans. His use of video is super easy to follow and he understands the time constraints of a busy lifestyle. Dr. Cohen is patient, professional and I recommend him without reservation."

Active Father of Two

""Dr. Cohen and his staff are outstanding. Very thorough with a great bedside manner, Dr Cohen makes it a priority to fully understand your issue and gives you exercises in the first session to start your road to recovery. He used my phone (with permission) to video me doing the prescribed exercises which is the most helpful method for recalling the process I've ever followed. I've been to many physical therapists, Cohen Health and Performance is the best!""

Physical therapy too often focuses on temporary relief. Rather than simply treating the source, the cause of pain and sub-optimal performance must be addressed accordingly. - Zachary Cohen
