Sleep Medicine Specialist


Dr. David D. Weisher is a board certified neurologist and sleep medicine specialist. He completed his neurology training at Georgetown University in Washington, D.C. in 1988. He was board certified in Neurology in November of 1989. While at Georgetown, he was also Chief Resident and upon completion of his neurology residency, he was appointed as Clinical Instructor to the Department of Neurology effective May 1, 1991. He continues to maintain that position but it is only honorary at this time as he now lives in St. Thomas.

Upon completion of his neurology training, he also obtained a fellowship in sleep medicine under Dr. Charlotte McCutchen. This was a 15-month fellowship under the auspices of Georgetown University and the National Institute of Neurological Disorders and Stroke. Dr. McCutchen was an early pioneer in sleep medicine.

Dr. Weisher is board certified in sleep medicine and has been a member of the American Academy of Sleep Medicine since February of 1989, when it was known as the American Sleep Disorders Association. Sleep disorders have always been a very important part of his practice.

Dr. Weisher is no stranger to the technical aspects of medicine. Prior to embarking on his career as a physician, he was an electronic aerospace computer engineer. He oversaw the development, research and product support for the computers involved in the transition between subsonic and supersonic flight in jet aircraft with wing sweep capabilities. This included the F-14 Tomcat and the B-1 Bomber. In that capacity, he worked for the Air Research Corporation, which is now part of the General Electric Corporation.

Dr. Weisher has held several positions, including the Chief of Neurology at Doctors Community Hospital, which was voted in the U.S. News and World Report magazine as one of the best medical centers for neurological care in the United States in 2001 and 2002 during his tenure. He was also Vice Chairman of the Medical Staff and Chairman of the Medical Quality Assurance Committee at that same hospital.

He has been a Medical Review Committee member at Washington Adventist Hospital in Maryland for many years, overseeing the quality of health care by physicians and surgeons in that institution.

He was kept very busy as a member of the teaching staff at the University of Maryland Residency Program at the Prince Georges General Hospital in Maryland, where he has given many lectures on neurology which included sleep disorders.

Dr. Weisher served on the Board of Trustees at the Prince Georges Hospice Society in Maryland.

He was a Clinical Researcher for the Parke-Davis/Phizer Pharmaceutical Corporation, which involved investigation of pharmaceutical therapies for Alzheimer’s disease.

He was also a Clinical Researcher in the carotid stent program under the auspices of the National Institute of Health. This work has been published in several articles and book chapters, as well as the June 2000 issue of the Journal of American College of Cardiology.

Dr. Weisher relocated from the Washington, D.C. area to the U.S. Virgin Islands in January 2003 and is currently the Staff Neurologist and Chief of Hyperbaric Medicine at the Roy Lester Schneider Hospital in St. Thomas.

He holds a medical license in Maryland, New York, and the U.S. Virgin Islands and is the author of two books. “Different but Equal” and “Mysteries of Consciousness” both deal with neurology and the nature of human consciousness.

Dr. Weisher, his wife Susan, and daughter Julia all enjoy the island life. When he is not working, he can often be found sailing or scuba diving for lost treasure.
