The Third Door Coalition provides the keys to solving chronic homelessness in Seattle

The Third Door Coalition is a nimble, solution-focused group of business leaders, service providers, researchers, and others who seek to move beyond typically polarizing discussions around homelessness. Instead, the Third Door Coalition seeks to open a third door: one where we work together and dedicate our collective energy to collaborative, evidence-based partnerships in pursuit of a singular goal. For the Third Door Coalition this goal is to solve chronic homelessness in Seattle.

The goal of the Third Door Coalition is to solve chronic homelessness in King County within five years through Housing First/permanent supportive housing.

Third Door Coalition’s is an IRS approved 501(c)3 nonprofit organization. Our EIN is 84-3429357.


We are unique because we are:

  • A coalition of Seattle-based researchers, business leaders, and service providers;

  • The only such coalition focused on the singular goal of solving chronic homelessness;

  • Intentionally small, comprised of fewer than 20 key partners to streamline decision-making and action;

  • Committed to a collaborative, non-polarizing process; and

  • Driven by data and interventions proven to work

Our Process

Our goal is as important as our process.

One of the Third Door Coalition’s guiding principles is that solutions are only possible through genuine interest and collaboration.

To ensure a forward-moving focus on solutions, the Third Door Coalition partners commit to a civil, collaborative, and genuine problem-solving process. This commitment to collaboration ensures that all partners share the same purpose and process by focusing on outcomes.

The Third Door Coalition also recognizes the need to remain a small governing group comprising fewer than 20 key partners to streamline decision-making and advance its vision of solving chronic homelessness through Housing First/permanent supportive housing. Third Door began in summer 2018 with focused conversations at Seattle University.
