Mercy Health Services announced Wednesday the opening of a new Preventive Care Center in Baltimore, part of the health care operator’s effort to provide patient education, greater access to care and resources to address social determinants of health. Located on the second floor of The Mead Building on North Calvert Street, the center will be an important step to expanding population health outreach and bringing needed medical staff under one roof to better serve our community, said Dr. David N. Maine, MHS president and CEO.
