Dr. William McCarthy is the Medical Director at the NOVA ABC Weight Loss Clinic

Dr. McCarthy has been in private medical practice in the Northern Virginia area since 1976.  He received a BS (Magna cum laude) at Xavier University in Cincinnati, his M.D. degree at Georgetown University in Washington, D.C, and served his internship and residency in Family Practice at the University of Wisconsin Hospitals in Madison, Wisconsin. Dr. McCarthy is board certified in bariatric medicine, which is the medical specialty of weight  disorders.  At this time, there are only approximatly 300 board certified bariatricians in the United States.

 
 He has served as the Chief of Staff and board member of Potomac Hospital here in Woodbridge.  He founded the nationally recognized Continuing Medical Education program at Potomac Hospital and served as it director for over twenty years.  He has been repeatedly voted by his peers as one of the top physicians in the D.C area in the Washington Consumer Checkbook.  Dr. McCarthy has also served as a board member of the Northern Virginia Foundation for Health and Medical Care and on the board of Physician’s Care insurance.  He was the team physician for the Prince William professional baseball team for many years, chosen by the Pirates, Yankees, Cardinals, and White Sox.   Dr. McCarthy has an outstanding reputation as a physician and educator, known not only for his broad knowledge of medicine, but also as a compassionate and caring physician.  After years of treating the health consequences that were brought on by excess weight, Dr. McCarthy decided to shift the focus of his care to the treatment and prevention of the actual cause of these medical problems.  Dr. McCarthy has attended numerous conferences, intensively studied the most current medical literature, and has spent time working with well known, experienced bariatricians in order to enhance his knowledge in the science of weight loss, metabolism, nutrition, exercise, and behavioral aspects of weight control.  He now dedicates his experience and knowledge to those who lives and health are adversely affected by their excess weight.
