In 1990, the Multi-Ethnic Mental Health Consortium was established by the Ohio Department of Mental Health. In 2003, the Consortium was formally organized, as the Multiethnic Advocates for Cultural Competence, Inc. (MACC) to make cultural competence a cornerstone in Ohio's behavioral health system. MACC conducted the first ever-statewide mental health needs assessment among eleven racial, ethnic and cultural communities titled, “Learning Your Needs” Cultural Competence Needs Assessment Project 2006; in 2008 the report was updated to include the Somali culture. In late 2010, the organization completed and released their latest report to include the cultures of Veterans and their families. ​ In 2010 the organization worked with Ohio’s state departments, cultural organizations, consumers, families and others to adopt the first in the nation state cultural competence definition to assist Ohio in moving towards cultural competence in service and care. In 2023 MACC established a partnership with Central State University, Mental Health Addiction Advocates Coalition (MHAC) and Ohio University to undertake a statewide data research project focusing on the BIPOC (black, indigenous, people of color) community. Also in 2023, MACC contracted with Deloitte to provide cultural competence oversight in the development of the Governor’s Wellness Workforce Initiative. Since 2010, the organization has expanded its work beyond the behavioral healthcare sector to include organizations and individuals seeking to better understand, work with and serve diverse populations.​ Through our mission and work, Multiethnic Advocates for Cultural Competence (MACC) has improved the quality of life for previously underserved populations throughout the state of Ohio and has expanded our efforts nationwide.
