Dr. Gallagher is a fellowship-trained orthopaedic surgeon specializing in trauma, reconstruction, joint replacement, and sports injuries around the foot and ankle. He received his undergraduate degree from Georgetown University and attended Thomas Jefferson University School of Medicine in Philadelphia for his medical education. He completed his residency and fellowship training at Union Memorial Hospital in Baltimore, Maryland. He also worked at Johns Hopkins Hospital and the University of Maryland Shock Trauma Center during that time. Dr. Gallagher manages a broad scope of conditions of the foot and ankle, including both primary and revision ankle replacement, as well as all forms of trauma, such as tibial pilon, ankle, calcaneal, talus fractures, and Achilles tendon injuries.

He is a member of the American Academy of Foot and Ankle Surgeons (AOFAS), where he was chosen to serve on the Research Committee. Through this position, he remains on the cutting edge of foot and ankle research nationwide. He has presented his research at national conferences and has published book chapters and scientific articles in journals, including The American Journal of Sports Medicine.

Dr. Gallagher utilizes cutting-edge techniques, including patient-specific-instrumentation for ankle arthroplasty, which uses a CT scan and a personalized plan to ensure a more reliable and efficient replacement. Additionally, he performs a minimally invasive approach to multiple conditions, including Achilles injuries, bunion correction, and hindfoot reconstruction.

Dr. Gallagher’s priority is finding strategies to keep his patients on their feet. He believes that one of the most important determinants of health is the ability to stay active. Often, that requires a nuanced view of the condition and the patient’s goals to devise a plan to optimize the outcome.

Originally from Philadelphia, Dr. Gallagher was a former club rugby and high school football player. He now enjoys cooking and spending time outdoors with his family.
