About San Rafael
San Rafael is Marin County's largest city (population 62,000) and the county seat, located about 20 miles north of San Francisco across the Golden Gate Bridge. It has a walkable downtown along Fourth Street, the original Marin General Hospital (now MarinHealth), and a more economically diverse population than much of wealthy Marin — with significant Latino and older working-class communities alongside affluent families. Kaiser operates a major North Bay facility in San Rafael.
