Robert Atlas, M.D.

Robert O. Atlas, M.D., leads Obstetrics and Gynecology at Mercy and is committed to keeping Mercy on the leading edge of care for new mothers and their babies. As Chair of Mercy’s Department of Obstetrics and Gynecology, Dr. Atlas provides leadership and guidance to a team of Mercy OB-GYNs. Additionally he is a key leader within The Family Childbirth and Children’s Center, regularly providing strategic direction and recommendations for enhancements to the patient experience.

Leadership in Obstetric Care in Baltimore

Dr. Atlas has been instrumental in keeping Mercy at the forefront of obstetric care. He played a vital role in the planning, designing and move of the Labor and Delivery and Mother-Baby Units to Mercy’s current, state-of-the-art hospital, The Mary Catherine Bunting Center. With all-private rooms, private baths, the availability of hydrotherapy tubs and the unusual offering of private NICU rooms, Mercy’s facility was carefully designed to provide comfort, convenience and privacy for new parents and their babies.

Dr. Atlas’ influence has spread beyond physical enhancements to the program as he regularly provides guidance and support for the care team on the Labor and Delivery and Mother-Baby inpatient floors, encouraging active communication between the clinical team and patients. He led Mercy to become the first hospital in Maryland to participate in a public cord blood bank program. Umbilical cord blood, often discarded, can provide life-saving treatments for both children and adults.

The Daily Record recognized Dr. Atlas as Physician of the Year as part of its annual Health Care Hero awards. He also has been named a "Top Doctor" by Baltimore magazine.
