A nonprofit organization


We envision - and strive to create - a world where every child that has experienced foster care has the opportunities and support they need to pursue their dreams and launch successfully into adulthood.

By 2027, 90% of youth who have experienced foster care across Washington state will complete high school, with support and a plan to transition into independence.

We directly support and work alongside more than 6,000 youth in foster care in Washington state, as well as their caregivers, educators, school administrators, and social workers, to ensure each young person has an individualized plan and network. We also advocate for systems-level change, informed by our on-the-ground expertise. Through direct programs and advocacy, Treehouse is uniquely positioned to close the opportunity gap and positively change the outcomes of youth who have experienced foster care.

Building on 35 Years

Treehouse turns 35 this year — powered by our incredible community of youth, caregivers, staff, volunteers, supporters and partners.

Our journey began when a group of social workers noticed that children in foster care were missing things other kids had — birthday presents, school supplies and field trips. The social workers started raising funds through bake sales and car washes to purchase everyday needs to help the children feel loved and capable.

From that original Little Wishes program, Treehouse has expanded over the years, committed to helping youth in foster care find a better path. We added a free store and distributed holiday gifts and financial assistance.

We developed new education programs, realizing that educational and racial disparities needed to be addressed to change outcomes and ambitiously set our sights on a high school completion rate matching their peers. We became involved in policy work when we saw that systemic barriers were stacking the odds against youth in foster care. 

While we have grown and evolved, the needs of youth in foster care have remained at our core. We have learned a lot about what it takes to be in their corner, and we are more committed than ever to centering their voice, choice and experience to shape their own journeys and ours.

The best part? We are just getting started as game-changers for youth in foster care as they reach for their dreams.

We've expanded our programs:  all school-aged youth in foster care across Washington state are eligible for all Treehouse programs.

We will now accept referrals from every corner of the state and we are expanding into new communities and school districts, including along the Olympic Peninsula and in central Washington. 

Graduation Success, Just-in-Time Funding and the Treehouse Store join Driver’s Assistance, Educational Advocacy and Holiday Magic programs to provide Treehouse services to young people experiencing foster care throughout Washington state.

Through these newly expanded programs, youth in foster care anywhere in the state will also have access to one-on-one academic coaching, financial support for extracurricular and school activities as well as free clothes and essentials.
