David N. Maine, M.D.

President & CEO 
Mercy Health Services

David N. Maine, M.D., is the President & CEO of Mercy Health Services (MHS), a patient-centered, integrated system, delivering high-quality, high-value health care services in various locations throughout the Baltimore Metropolitan area and State of Maryland. At its center is Mercy Medical Center, a general acute care teaching hospital, affiliated with the University of Maryland School of Medicine, located in the heart of Downtown Baltimore, and founded by the Sisters of Mercy in 1874. Dr. Maine’s appointment as President & CEO marks the first time a physician has led the hospital and health system in its 145-year history. 

Dr. Maine, who previously served as Executive Vice President for Mercy Health Services since October 2019, is responsible for all MHS operations, overseeing the Medical Center, specialty and primary care physician networks, and Mercy affiliates. Prior to assuming the role of Executive Vice President of Mercy Health Services, he was Executive Vice President of Mercy’s Physician Enterprise, focusing on the growth of its physician network. His other roles at Mercy have included serving as President of Medical Staff; as Senior Vice President of Clinical Transformation, leading Mercy’s efforts to launch the SurgCenter of Towson; and since 2007, as Medical Director of The Center for Interventional Pain Medicine at Mercy, perennially earning the distinction as a Baltimore magazine “Top Doctor”.

Dr. Maine lives in Pikesville, Maryland with his wife and two children. He was born the son of Jewish-Iraqi refugees who fled Iraq for Europe in 1972 due to the ongoing persecution of the religious minority. With the assistance of the Hebrew Immigrant Aid Society, an international refugee aid organization, Dr. Maine’s family eventually immigrated to the United States, settling in Rochester, New York in 1974.

Dr. Maine attended local public schools in Irondequoit, New York. He then matriculated at the University of Rochester School of Arts and Science and the University of Rochester School of Medicine, graduating in 2002 with Alpha Omega Alpha honors. He completed his Residency in Anesthesiology and his Fellowship in Interventional Pain Medicine at The Johns Hopkins Hospital and is Board Certified in Anesthesiology and Pain Medicine.
