Nearly every city in the US has a Tenderloin. Here in San Francisco, it’s a neighborhood home to a dozen social service agencies, low-rent residential hotels, or SROs, and thousands of low-income – and-no-income – residents. Premature deaths from HIV/AIDS, heart disease, and complications from substance use and abuse mark the lives of many in the Tenderloin. It’s a part of the city known for open drug use. A place many people avoid and one where individual lives can be easily forgotten.
