Housing First was developed by Sam Tsemberis in partnership with people experiencing homelessness, mental illness, and addiction. It is an evidence‑based approach to ending homelessness that provides immediate access to permanent housing and flexible, person‑centered support. 

The Pathways Housing First Institute (Pathways) partners with organizations, municipalities, states, and countries to deliver effective, person‑centered Housing First programs. We provide strategic planning, program development support, implementation guidance, workforce training, and practical tools that help teams strengthen practice and build sustainable capacity.
