The Maryland Association of County Health Officers (MACHO) is a private, nonprofit organization whose primary purpose is to promote the health and well being of Maryland citizens. In so doing, it actively cooperates and works with MACo, the State Department of Health and Mental Hygiene, the State Department of the Environment; and other health-related or complementary agencies, organizations, individuals, and community groups. Its activities involve education, liaison, and public health policy development and implementation.

The Nominating Committee presents a slate of officer nominations in November for the annual election in December. MACHO meets monthly on the second Thursday of each month.
