Maureen Tart, MD, FACOG, NCMP, is a board-certified OB/GYN. Before joining the practice in 2011, Dr. Tart practiced in Chicago for over a decade. She served as Co-Medical Director of her group and held the role of Vice Chair of the OB/GYN department for several years.
Originally from Connecticut, Dr. Tart moved to Chicago for her residency training and has since built a career dedicated to women’s health. She earned both her undergraduate degree in psychology and her medical degree from Georgetown University before completing her residency in Obstetrics and Gynecology at the University of Chicago Hospitals. During her residency, she served as the academic chief resident and trained alongside Dr. Heather B. Heiberger, MD, FACOG, and Dr. Elizabeth Oh, MD, FACOG.
