"Philosophy of care | I want to get to know you, first as a person, not as a patient. I want to know what kind of work you do, what sports you play, and what hobbies/extracurricular activities you enjoy. I will then take your medical history, my physical exam, and diagnostic studies to come up with a diagnosis. I will teach you about your problem and the most up-to-date treatment options, including what tends to work (and not work). I will help you improve and reach an outcome you are pleased with through mutual decision-making, making sure to exhaust all non-operative measures. As partners, we weigh the risks and benefits of various options and choose a plan we are both happy with. If the answer is surgery, I will help you through the process and be with you every step of the way on your recovery. I treat all patients like family, but also use the scientific orthopedic literature to help guide the decision-making process. | Why I entered medicine | I grew up in Florida and my father was an ophthalmologist (and original Tampa Bay Rays eye doctor). With my mother being a nurse, I was always exposed to medicine. I saw my parents helping people and was inspired to pursue medicine as a career. That, plus my love for sports, sciences, biomechanics and anatomy, led me toward orthopedics. It's very rewarding to help people get their function, motion and quality of life back. As a collegiate baseball player, I was drawn to the anatomy, biomechanics, and function of the upper extremity, and how to rehab and treat the common injuries. As the team hand surgeon for many local high schools, colleges and professional teams, I understand what it takes to get you ""back on the field."" | Community involvement | I have worked with local high school students interested in health care and led them through several upper extremity cadaver dissections. I am also the team hand surgeon for many local high schools, Lehigh University, Kutztown University and Muhlenberg College to name a few. I am the hand surgeon for the American Hockey League - Lehigh Valley Phantoms. In my spare time, I coach Little League baseball in the South Parkland Youth Association. | Personal interests | Professionally, I enjoy teaching our next generation of physicians: high school students, medical students and plastic surgery residents, in the office and the OR. | Personally, I enjoy traveling, the beach, all four seasons the Lehigh Valley has to offer, and spending time with my wife and four children. I am often a part-time chauffeur for my kids' activities, as well as a Little League baseball coach. | 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.
