David Z. Liao, MD

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.

ACCEPTING NEW PATIENTS STARTING DECEMBER 1, 2025. Every year since completing my residency, Ive continued to learn from colleagues as well as my patients. I have the rare opportunity, each year, to join with some of the worlds best sinus surgeons to train other ENT physicians in the techniques of endoscopic sinus surgery at the University of Pennsylvania. I come away from this experience with improvements in my technical expertise. My patients ultimately benefit from what I learn.
