Philosophy of care | My goal is to make sure you know that you have my full attention at each office visit. We will work together to diagnose and treat each injury. I want you and your family to feel completely comfortable with the plan of care. Each patient's recovery to their fullest potential is my ultimate goal. | Why I entered medicine | For as long as I can remember, I wanted to become a doctor. After playing multiple sports in high school and then Division I college football, and suffering multiple injuries along the way, orthopedic surgery was a natural fit. | Community involvement | I have been a youth sports coach for football, soccer, baseball and basketball. I also volunteer for many community groups. | Personal interests | I am a sports fan at all levels: high school, college and professional. I also enjoy hiking, biking and fishing. | 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.
