Meet Our Doctors

Robert Posner, M.D., President and CEO
Robert Posner, M.D. graduated with Phi Beta Kappa honors from Binghamton State University with a degree in biochemistry. He then attended Downstate Medical School in Brooklyn, New York on a United States Navy scholarship. Dr. Posner completed an internal medicine residency at Naval Hospital Portsmouth and became a Diplomate of the American Board of Internal Medicine in 1984. He was awarded Teacher of the Year for the Family Practice program at Naval Hospital Jacksonville in 1986 and was interviewed to be the physician to President Reagan in 1987.
Dr. Posner started a private practice in Northern Virginia in 1988 and was one of the first physicians in the area to opt out of all insurance company participation by building a boutique type of practice that focused on patient satisfaction, empathetic care and patient loyalty. In 1998 he began work on the development of the first oral serotonin supplement which culminated in patent approval (U.S. Patent Number 6,017,946) in January 2000.
He established the Serotonin-Plus Weight Loss Program in October, 2002 and this has since grown to be the largest medically supervised weight loss program in the Washington, D.C. area. Over 10,000 patients have been placed through the program with excellent safety and efficacy.
Dr. Posner has written three books, “Doctor, I Have a Chemical Imbalance-The Serotonin Story”, “The Stress Eater Diet Book” and “The Serotonin Solution for Never Dieting Again”. He has appeared as an expert on television and radio shows and lectures to the American Academy of Anti Aging Medicine.
Although the Serotonin-Plus Program is expanding nationally, Dr. Posner still sees internal medicine patients as well. He resides in Burke, Virginia, plays tennis and works out daily.
