Overview
I wanted to become a Physician Assistant out of my desire to help people feel well and live healthy lives. I first began working with gastrointestinal (GI) patients in clinical trials before attending physician assistant school. After receiving my degree and working in primary care for several years, I decided to return to GI to use my knowledge and experience to help patients achieve their health goals. Working with my patients on their individualized treatment plan and developing a good patient-provider relationship is very important to me as well as providing compassionate care. In my spare time I enjoy staying active and keeping up with my three children.
