Dr. Robert A. Vigersky was the 1970 valedictorian graduate of the pioneering six-year program in liberal arts and medicine of Boston University, where he was elected to Phi Beta Kappa and Alpha Omega Alpha. He did his internship and residency in internal medicine at The Johns Hopkins Hospital and then completed a three-year fellowship in endocrinology at the National Institutes of Health (NIH), becoming board certified in both internal medicine and endocrinology and metabolism. He remained on the staff at NIH for two years and then transferred to Walter Reed Army Medical Center, where he served as assistant chief of endocrinology until 1984.

He subsequently entered the private practice of endocrinology and became president of the Endocrine and Diabetes Group of Washington — a large, single-specialty practice with three offices in the metropolitan Washington, D.C., area. Dr. Vigersky was also medical director of the Diabetes Treatment Center at Georgetown University Hospital and the Washington Hospital Center, and was voted one of Washingtonian magazine's top doctors in 1991, 1993, 1995, 1997 and 1999.

Dr. Vigersky is the representative to the American Medical Association from The Endocrine Society and has been a member of the society's governing council as well as chairman of its clinical affairs committee and clinical guidelines committee. In 2000 he re-entered the Army, establishing the Diabetes Institute of the Walter Reed Health Care System, of which he is the medical director. Dr. Vigersky has published 72 scholarly papers and 71 abstracts in his specialty and has lectured widely. He is a professor of medicine at the Uniformed Services University of the Health Sciences and received the James Leonard Award for Excellence in Teaching in 2003.
