MICHAEL C. PETRINA

OWNER // BIOMECHANICS THERAPIST

Michael C. Petrina is a Biomechanics Therapist and the owner/operator of PRIME, an innovative sports performance facility combining fitness, movement and biomechanics. He coined the term based on his approach to treatment and training. Michael specializes in pre-injury and post-rehab strength training and treatment. His treatment concentrates in neuromuscular structural integration that resolves injuries and discrepancies in biomechanics and anatomy. His cross-functional approach minimizes downtime as his clients can continue to build strength and flexibility while overcoming injury. Studying under Dr. Keith Pyne, a pioneer in corrective therapy, for many years, Michael has honed his treatment skills and developed a system that corrects the actual cause of the pain. Unlike traditional methodologies that only treat symptoms providing just temporary relief, Michael's system is unique in that he incorporates manual therapy, proprioception, and corrective patterning to reset the brain's connection with the body. Addressing the problem where it starts, in the body's kinetic chain, is paramount in Michael's treatment philosophy - and why his clients consistently improve their performance. 

Michael has worked with several professional athletes in post injury rehabilitation and biomechanical efficiency. He is a consultant with professional sports teams, assisting in the treatment and design of programs to reduce the chance of injuries.
