CHNA 17 is a regional health coalition focusing on mental health and racial equity. CHNA 17's mission is to promote healthier people and communities by fostering community engagement, elevating innovative and best practices, advancing racial equity, and supporting reciprocal learning opportunities to address the needs of the most marginalized members of our communities. The CHNA has existed as a regional health coalition since 1992, serving Arlington, Belmont, Cambridge, Somerville, Watertown and Waltham. The coalition's work is funded primarily through a Determination of Need (DON) allocation from Mount Auburn Hospital, and McLean's Hospital. The Cambridge Public Health Department/Cambridge Health Alliance also contributes to the CHNA's community grants.
