Mission & Focus Areas

The foundation’s stated purpose is to make capital grants exclusively in California and Hawaii. It prioritizes organizations providing basic needs such as shelter and food, medical facilities, and private schools, with particular focus on the Greater Bay Area and Hawaii.

Examples of supported organizations illustrate the range of work among its grantees. Children’s Day School describes its mission as balancing academic learning with students’ personal development. Dynamic Community Solutions describes its work as providing communal living solutions to address homelessness. An individual recipient Medical Center Foundation says it supports the mission of an individual recipient Medical Center and the provision of medical care. These are grantees’ descriptions of their own missions.

In 2024, the foundation awarded 117 grants totaling $10,840,417. Grants ranged from $5,000 to $400,000, with a median of $50,000.
