James W. Horn, MSPT

(Jim) received his undergraduate degree from Cornell University, with a Bachelor of Science. He returned to school shortly afterwards where he earned his masters in Physical Therapy from Columbia University.

Jim has worked with a diverse group of people with a wide range of physical therapy needs. Jim has worked with babies, teens and adults in several settings, including early intervention and the NYC Department of Education. The youngest client Jim worked with was 4 months old, while the oldest was 104 years of age. Jim greatly enjoys the different challenges that working across such a broad spectrum offers.

Jim’s interests in running, weight lifting, golf, and platform tennis (paddle) help him relate to his patient’s goals of resuming their functional lives. Jim has continued his professional education in areas including knee, shoulder and spine rehabilitation, with a strong focus on manual interventions and active patient participation. Jim believes that a person’s successful rehabilitation begins with understanding what it is that motivates each individual to get well.

Jim currently lives on Long Island with his wife and three young children.
