Ben Shen, MSPT


Ben joined our staff at Casco Bay PT in January, 2019.  Ben is graduate of Boston University's Sargent College and has practiced PT since 1990 in a variety of settings including acute care, rehabilitation, and outpatient orthopedics and neurology. He uses a combination of pain-free manual methods and neurologic approaches to treat sports injuries and pain syndromes. He was most influenced by the gentle NDT approaches he observed at Holy Ghost Hospital in Cambridge, and the mechanical rationale of scientists at MGH Institute. His methods developed from feedback he received working with patients recovering from stroke and spinal cord injury. He has expanded these methods to speed recovery for those coming back from muscle injury, joint replacement, stroke, multiple sclerosis, and Parkinson's disease. When he is not learning from his patients, he enjoys reading 18th century maths and running outdoors under night skies. Ben's email is: ​BShen@cascobaypt.com
