Treatment Philosophy

Breast cancer care is constantly evolving and advancing, and I feel fortunate that my surgical practice can be focused exclusively on patients with breast cancer, those at high risk for it, and those with complex benign breast conditions. Use of a multidisciplinary approach, opportunities for clinical trials, and distribution of quality information to patients are opportunities that I strongly value when providing care to patients. 

My philosophy is that offering patients a strong physician-patient relationship built on trust, collaboration, and kindness, as well as valuing the “whole patient” are also strong tenants of cancer care. I believe in providing patients with knowledge and conversation in order to help them make the best treatment decisions for themselves. Fox Chase Cancer Center provides high quality care and extensive resources to patients, and I feel honored to be a part of such an excellent team and institution that believes so strongly in compassionate and thoughtful care.
