Letter from Leadership

Dear Community Members:

Since 1989, the Community Partnership has worked to treat and prevent homelessness in Washington, DC.  TCP has become one of the country’s most successful Continuum of Care managers and is a respected steward of more than $80 million of federal and local government funds annually. HUD has honored The Community Partnership several times for our strong data collection and as a “National Best Practice Model” by the National Alliance to End Homelessness for our work to keep families from falling into homelessness.

We hope this website will be a resource for individuals and families seeking help, our providers serving the homeless population, landlords interested in housing individuals and families, and those seeking statistical information about the homeless population in Washington, DC. Thank you for visiting our site!

TCP will remain a trusted partner to government and homeless service providers, ensuring quality services to our city’s neediest residents.
