Mission & Focus Areas

The foundation’s mission is to inspire enduring philanthropy and enable community solutions to improve the quality of life in its region. Its current strategic plan names four priorities: creating transformative impact, motivating community action, inspiring informed giving, and deepening organizational excellence. Its focus areas are family well-being, education, environment, and housing. The foundation also describes its discretionary and competitive grantmaking as aligned with advancing racial and social justice, fostering equity of opportunity, and building resilient communities.

The foundation considers applications from 501(c)(3) nonprofit organizations whose work aligns with its mission and priority impact areas; it does not award grants to individuals. Depending on the program, funding may support projects, capacity building, or core operations and general support. Examples of grantees’ work include the Community Foundation for Monterey County, whose mission is to inspire philanthropy and strengthen Monterey County communities; UC San Diego Foundation, which raises private support for the university’s research, teaching, and public service; and Just Transition Alliance, which seeks to help communities and workers transition from unsafe workplaces and environments to healthy, viable communities with a sustainable economy.

The 2025 filing lists 1,158 grants totaling $94,296,130. Grant amounts ranged from $5,100 to $4,956,124, with a median of $25,000. Separately, the foundation’s fast facts report that it awarded $96.8 million to the nonprofit community in fiscal year 2025.

Among the largest grants listed for 2025 were $4,956,124 to Community Foundation for Monterey County, for its “Bob” Fund; $3,739,925 to UC San Diego Foundation for general support; $2,195,000 to Policy & Innovation Center for support of the an individual recipient Regional Policy and Innovation Center; and $1,912,356 to Just Transition Alliance for its time as part of the TCC Post Award Consultation.

Requests may range from $10,000 to $40,000 for a 12-month grant cycle beginning with the award in December 2026.
