Philosophy of care

In a world where it seems like practices are becoming larger and less personal, our office is still a small two practitioner practice. This allows a patient to be able to see the same physician in the practice and for that doctor to be able to know that patient and his or her family as well as he can.

Why I entered medicine

I had originally entered college planning to become a chemical engineer. After a semester of math and science, I decided that I wanted a profession where I could feel like I was directly impacting people's lives on a daily basis. I really cherish getting to know my patients and their families.

Community involvement

I am involved in my son's team sports and school events. I am a lector and an RCIA sponsor at my church and enjoy playing tuba in the Nazareth Community Band.

Personal interests

I enjoy playing tuba, gardening and running.
