I became a physician because I wanted to help people. I enjoy the challenge and find the work fulfilling.

I believe in patient-centered care. I take the time to listen to your OBGYN issues and work with you to find a solution. I enjoy taking care of women from adolescence through menopause and providing continuity of care. My favorite areas of OBGYN are high-risk obstetrics and minimally invasive surgery.

Outside of work I have three children of my own who keep me very busy. I am athletic and enjoy running, golfing, beach volleyball and basketball.
