Mission and History South End Community Health Center (SECHC) is a comprehensive health care organization for all residents of the South End and surrounding communities. We are committed to providing the highest quality, coordinated health care that is both culturally and linguistically sensitive to every patient, regardless of ability to pay. SECHC was founded in 1969 by neighborhood activists in response to health care disparities and lack of access to quality health care in Boston’s South End.
