About Philip Kaiser, MD

Dr. Philip Kaiser aspires to help patients mobilize to their fullest capacity and improve their foot and ankle health, applying both operative and non-operative therapies. He believes that quality of life - for many people - is linked to the function and mobility of their lower extremities. Through his extensive training in orthopaedic surgery and sub-specialty training in foot and ankle surgery, he seeks to help patients recover from injury, mitigate pain and maximize their physical abilities. He recognizes there is a different path of recovery for each patient with injury or disability. He is dedicated to helping patients customize their treatment to restore their mobility and function.

Dr. Kaiser is a fellowship-trained orthopaedic surgeon, specializing in injuries and conditions of the lower extremity. He completed his undergrad degree in economics and psychology, while also studying premedical science, at Harvard College. As an undergraduate he was a 4-year member of the national championship heavyweight men’s crew team and represented Canada internationally as a competitive rower. He went on to receive his medical degree from the College of Physicians and Surgeons at Columbia University in New York City. He then completed his residency at Harvard, training at Harvard-affiliated hospitals including Mass General, Brigham & Women's, Boston Children's and Beth Israel Deaconess Medical Center. In his final year he was named chief resident at Beth Israel Deaconess Medical Center. After his residency, he attended the OrthoCarolina Foot and Ankle fellowship in Charlotte, North Carolina, focusing on the newest surgical treatments for orthopedic trauma, sports-related injuries, cartilage restoration, ligament and tendon disorders, foot and ankle reconstruction including ankle replacement, forefoot and bunion correction, diabetes and charcot, and minimally-invasive foot and ankle surgery.

While outside the operating room and clinic, Dr. Kaiser is actively involved in academic research and teaching, with more than 20 peer reviewed publications in the past five years. He is also interested in the study and development of new orthopaedic implants and devices, which advance the field of orthopaedics and improve the lives of patients.

Dr. Kaiser is looking forward to serving the residents of Boston and surrounding areas. He is now practicing in Boston at Mass General and Newton Wellesley Hospital and their affiliates.
