Marin Community Clinics (MCC), a federally qualified health center, is the largest provider of comprehensive primary care, oral health, and behavioral health services to low-income residents (those earning less than 200% federal poverty level) in Marin County, California. Founded in 1972 as a free clinic at a local church, its mission today is to improve the health of patients and community by providing high quality, cost-effective, culturally sensitive, patient-centered health care. Marin County faces unusual health care challenges. While the county itself is among the most affluent in the nation, it has pockets of low-income populations such as the Canal neighborhood of San Rafael that are impoverished and where residents face difficulty in meeting basic needs such as food, shelter, and health care. Without the community support Marin Community Clinics receives, thousands of women, men, teens, and children would have little or no access to regular, ongoing medical care. The presence of Marin Community Clinics means more people are receiving regular check-ups and are immunized, employees can stay healthier, and medical problems are addressed before they become life-threatening, expensive to treat, and use public dollars.
