Mount Sinai Hospital

Dr Gretz is a Clinical Professor of Obstetrics and Gynecology at the Ichan School of Medicine at Mount Sinai.

Dr. Gretz specializes in surgery for women with either malignant or benign diseases as well as patients at risk for heriditary cancers. These conditions include ovarian cysts, endometriosis, fibroids, abnormal bleeding, as well as cancers of the ovary, uterus, cervix, vulva.

His specific area of expertise is minimally invasive surgery including either robotic or laparoscopic procedures. These operative techniques typically shorten hospital stays, and allow patients to recuperate faster. Dr. Gretz operates with the philosophy that each woman needs to be considered individually, and that every surgery should be tailored to the disease process and needs of each patient.
