Dr. Byrne, a native of Ireland, obtained his medical degree at The Royal College of Surgeons in Dublin, Ireland. After initial training in surgery in Ireland and England, he came to The Medical College of Virginia (MCV), as a research fellow, and completed his surgical residency at MCV. While a resident at MCV, Dr. Byrne developed an interest in weight loss surgery, under the mentorship of Dr. Harvey Sugerman. After residency, Dr. Byrne was appointed on staff at The Medical University of South Carolina, as a trauma and critical care surgeon. Because of a need to provide weight loss surgery to morbidly obese patients in the area, Dr. Byrne started a small program at MUSC in 1992. Since then the program has grown exponentially and in 2006 was designated by the American Society for Metabolic and Bariatric Surgery (ASMBS) as a Center of Excellence.
Dr. Byrne currently practices as a general surgeon, with a special interest in weight loss surgery which comprises 80% of his practice. He has performed over 2,000 bariatric cases including open and laparoscopic gastric bypass, adjustable bands, sleeve gastrectomies as well as revisions. Dr. Byrne is a Professor of Surgery, board-certified by The American Board of Surgery, and is also a fellow of The Royal College of Surgeons in Ireland. He is a member of ASMBS and is the medical director of the Bariatric Surgery Program at MUSC. Dr. Byrne enjoys student and resident teaching, and has won several teaching awards, including a Golden Apple.
