Brian Weisman, PT, CERT. MDT, CMP, CDNS
Brian graduated magna cum laude from Quinnipiac University in 1997 with a B. S. degree in physical therapy. After graduation, he returned home to Maryland to begin his physical therapy career, working as a staff therapist for a large corporate outpatient physical therapy company.
Brian then went on to open his own physical therapy company in May 2000, and with his two partners expanded it to 16 locations throughout the Baltimore metropolitan area. In 2015, Brian decided he wanted to get back to a more intimate therapy setting, overseeing only one clinic in Frederick, Maryland, where he could spend more time seeing patients.
Brian holds numerous post-graduate manual therapy certifications, and in 2008 became certified through McKenzie Institute for Mechanical Diagnosis and Treatment (MDT) of the spine and extremities. He is currently certified in ASTYM, as well as a Certified Mulligan Practitioner (CMP), and as recently as 2015 became certified in Trigger Point Needling (TDN). Brian’s focus throughout his 20-year career has been primarily outpatient orthopedic conditions, post-surgical care, balance/fall prevention, and treatment of patients suffering from vertigo.
Brian is a huge believer in continuing education and always strives to become a better therapist by listening to patients and tailoring every treatment to their needs.
