Philosophy of care | Most patients with back or neck pain do not need surgery. I believe my job is to discuss all the options with you so together we can make an informed decision about your care. I think patients do better when they play an active role in their treatment. | Why I entered medicine | I knew early on that I wanted to be a surgeon because of its hands-on aspect. My mother was an operating room nurse, so I had the opportunity to observe surgery while in high school. This experience steered me toward orthopedic surgery. | Community involvement | We are active in our church and with the various sports organizations in which our children are involved. | Personal interests | When not working I enjoy reading, guitar, golf and cycling. | Image | Lehigh Valley Hospital is ranked 25th in the country for orthopedic care on the 2025-2026 U.S. News & World Report Best Hospitals list. Our team of more than 200 orthopedic specialists provide award-winning, nationally-recognized care with experience, expertise and leading-edge technology. |.
