About William A. Berrigan, MD, RMSK

Dr. Bill Berrigan is a primary care sports medicine doctor who focuses on helping patients of all ages stay active, reduce injury risk and achieve peak performance.

Dr. Berrigan is board-certified in Sports Medicine, Physical Medicine and Rehabilitation and Musculoskeletal Sonography, and fellowship-trained in Primary Care Sports Medicine.  Dr. Berrigan has a particular focus on providing ultrasound-guided injections and non-operative care for patients with acute sports injuries, chronic disorders and pain conditions.

An avid researcher, Dr. Berrigan’s clinical research interests include: non-invasive measures for diagnosis and treatment of chronic exertional compartment syndrome; ultrasound shear wave elastography as a diagnostic and prognostic tool for musculoskeletal pathology and interventions; and evidenced-based use of orthobiologics, which involve using a patient’s own cells and growth factors to treat an injury.

Dr. Berrigan earned his medical degree at St. George’s University School of Medicine, Grenada, West Indies. He completed an internship in internal medicine at the Hackensack Meridian Jersey Shore University Medical Center, and followed with a residency in Physical Medicine and Rehabilitation at Medstar Georgetown National Rehabilitation Hospital.  Dr. Berrigan then completed fellowship training in Primary Care Sports Medicine at Emory University School of Medicine where he served an additional year as chief fellow focused on teaching and academic leadership.

While at Emory, Dr. Berrigan provided sports coverage for the Atlanta Falcons (NFL), the Atlanta Hawks (NBA) and the Atlanta Dream (WNBA).  He served as head team physician for the professional Fan Controlled Football (FCF) league and assistant team physician for the College Park Skyhawks, the G league affiliate of the Atlanta Hawks.  During his undergraduate years at Villanova University, he was a hammer thrower on the school’s Division 1 Track and Field team.  Additionally, he has also been involved in competitive bodybuilding. 

Dr. Berrigan grew up in San Marcos, California.  He enjoys spending time with his family, traveling, hiking national parks and following Villanova basketball.
