Practice Philosophy

I am passionate about helping women with breast disease and believe my job as a surgeon is to connect with my patients and their families to help them through the process of evaluating all treatment options. I work with the experts around me to provide individualized care, and strongly believe in maintaining a woman’s femininity when making surgical decisions.

This doctor is employed by Main Line HealthCare, the multispecialty physician network of Main Line Health, including more than 350 community and hospital-based physicians.
