Mission & Focus Areas

The foundation states that it advances equity and sustainability by increasing opportunities for vulnerable young people and communities. Its three pillars are youth access to play, youth homelessness, and environmental justice.

For youth access to play, the foundation describes work to reduce barriers to sports, including support for hockey access and programming at Kraken Community Iceplex, equipment donations, ball hockey training, and financial assistance. Its website describes partnerships and programs that offer skating and hockey opportunities to young people.

For youth homelessness, the foundation identifies YouthCare as its primary partner. Its 2024 filing also describes work with Community Passageways, including fundraising and support for shelter, housing, education, and employment training, as well as job training, internships, and employment opportunities through the Seattle Kraken and Climate Pledge Arena. For environmental justice, the foundation says it supports communities disproportionately affected by climate change.

The foundation also provides grants and support to nonprofits whose work aligns with its pillars. Examples among its 2025 grantees include YouthCare, which says it works to end youth homelessness, and Special Olympics Washington, which says it provides inclusive sports, health, and leadership programs for people with intellectual and developmental disabilities. Treehouse describes its mission as supporting children who have experienced foster care, while the Urban League of Metropolitan Seattle says it works to secure educational and economic opportunities for African Americans and other underserved communities.

Grantmaking

In filing year 2025, the foundation reported 58 grants totaling $1,636,600. Grant amounts ranged from $5,600 to $119,000, with a median of $32,000.

All Girl Everything Ultimate Program received $32,000 for youth access to play.

The foundation’s website says donation requests must be submitted through its online portal and that individual solicitations without a submitted form will not be accepted.
