Marcus Rein
Marcus Rein

Marcus began his journey into the world of movement science years ago when he played for the USA Men’s Soccer youth teams from ages 13 to 19 as well as Division 1 collegiate soccer at Wake Forest University and the University of Central Florida. Here he was exposed to Olympic lifting, exercise programming, and the relationship between high-quality movement and sports performance. During this time he sustained many injuries, some of which resulted in orthopedic surgeries followed by physical therapy. It was while recovering he realized the close connection between the efficient movements taught by physical therapy and their importance in supporting the physical demands of sport. After his soccer career ended, Marcus coached Santa Cruz athletes in the balance between sports performance and injury prevention for six years. While coaching, he achieved certifications through the National Academy of Sports Medicine as a Performance Enhancement Specialist (PES) and a Corrective Exercise Specialist (CES), a Functional Movement Screen (FMS) Level 1 instructor, as well as a CrossFit Level 2 instructor. He then furthered his understanding of rehabilitation, movement impairments, and injury prevention by entering graduate school at Samuel Merritt University to earn a Doctorate in Physical Therapy in 2016. He began practicing for three years in an outpatient orthopedic clinic in Santa Cruz, CA and has been working at Back in Motion since May 2019. He enjoys assisting his patients and clients achieve their functional goals using a blend of strength and mobility training that is tailor-fit to their needs. When not treating patients, Marcus can be found spending time with his fiance, working out, relaxing with his favorite music, or performing in open-mics around town.
