The Delancey Street Foundation, often referred to simply as Delancy Street, is a non-profit organization based in San Francisco that provides residential rehabilitation services and vocational training for substance abusers and convicted criminals. It reintegrates its residents into mainstream society by operating various businesses - such as restaurants, moving companies, and print shops - all of which are wholly managed and run by the residents themselves. The foundations' methods have been widely praised and have been emulated internationally.
