My prior military service has made me a more well-rounded physician. As a Naval Flight Surgeon for three years, I was solely responsible for the medical care of my squadrons pilots, navigators and support crew, particularly during deployments to Bermuda and Iceland. I also served as the Navy's sole ENT on board the USNS COMFORT, a trauma-care ship, for three years. Lastly, after graduating from my residency I continued at Bethesda Naval Hospital as an attending physician. -John M. Bosworth, Jr., MD, FACS -- To schedule an appointment with Dr. John M.
