Patient Age Group


I have been an attending physician at Mass General hospital since 1993. Currently, I am the Division Director of Benign Gynecology and Obstetrics and the Associate Director of the  third year clerkship director for MGH at Harvard Medical School. I provide specialized gynecologic care for abnormal bleeding, fibroids and endometriosis, including up to date  medical and surgical technologies such as endometrial ablation, hysteroscopic surgery and laparoscopic  and vaginal hysterectomy and myomectomy. I enjoy longstanding relationships with patients, and guide them through OB/GYN care through their life span. Within my practice at MGH West I care for many women with advanced maternal age pregnancy. I also have expertise in  minimally invasive gynecologic surgery, perimenopause and the gynecologic care of breast cancer patients. In addition to teaching, I am interested in patient safety, teamwork training and simulation within the department. My primary focus however is personalized patient care within the outstanding OB/GYN department at MGH.
