Finding a breast lump or being told of abnormal breast imaging can be very frightening. As a member of the comprehensive breast care team at Stony Brook, I take care of patients with both malignant and benign diseases of the breast. I help guide them through the process and treatment, whether additional diagnostic tests or surgery is needed. My particular interests are in breast-conserving surgery, sentinel node sampling, mastectomy, high-risk screening and preventative surgery. My goal is to provide high-quality care and compassion to all patients.
