The St. James Infirmary (abbreviated SJI), founded by members of the sex worker activist community in 1999, is a peer-based, full spectrum medical and social service organization serving current and former sex workers of all genders and their families. Located in the Tenderloin district in San Francisco, California, the St. James Infirmary is a 501(c)(3) public charity. Its services are free and confidential. Named after the sex workers' rights activist and founder of COYOTE (Call Off Your Old Tired Ethics), Margo St. James, the St. James Infirmary is the first occupational safety and health clinic for sex workers run by sex workers in the United States.[citation needed]
