The Massen Greene Foundation concentrates its giving on local environmental and marine conservation in the Laguna Beach/Orange County area, funding a very small set of organizations with large, unrestricted contributions. Most support goes to hands-on coastal and marine rescue and habitat preservation efforts, and grants are targeted to organizations that operate locally rather than to broad national causes.
Highly concentrated: few, relatively large grants focused on a small number of repeat local environmental grantees; gives unrestricted/contribution support rather than many small or diversified awards.
Massen Greene Foundation C/o Larry D Vince has made one of its clearest recent commitments through repeated, large support for Pacific Marine Mammal Center, including a $560,000 grant in 2025 and a $440,000 grant in 2024. That pattern sits alongside sustained funding for Laguna Canyon Foundation and other Orange County organizations working on coastal conservation, habitat stewardship, and local education. The foundation’s recent giving is concentrated in a small circle of recipients, with multi-year support that points to long-running relationships rather than broad, one-off distribution. Its largest recent grants are paired with additional awards to local environmental groups, a school scholarship fund, and community organizations in Laguna Beach, Newport Beach, and nearby cities. The grants are structured as contributions in furtherance of each recipient’s exempt purpose, and the portfolio includes both conservation and community-serving nonprofits. A small number of organizations account for much of the activity, including Pacific Marine Mammal Center, Laguna Canyon Foundation, and Boys and Girls Club of Laguna Beach. The result is a funder profile centered on place-based support in coastal Southern California, with marine mammal care and local habitat preservation at the core.
Marine mammal rescue and rehabilitation is a defining theme in the foundation’s recent grants. Pacific Marine Mammal Center received $560,000 in 2025 and $440,000 in 2024, after a $120,000 grant in 2023. That kind of repeated support signals a sustained relationship with a single local responder. Land and watershed stewardship is another recurring area. Laguna Canyon Foundation received $145,000 in 2023 and the same amount again in 2024, followed by $95,000 in 2025, tying the funder to canyon habitat preservation in Laguna Beach. The foundation also backs local environmental education and conservation outreach. Environmental Nature Center received $90,000 in 2025, $52,000 in 2024, and $40,000 in 2023, while Crystal Cove Conservancy received $100,000 in 2023.
The typical grant sits at a meaningful local scale, with a p25 of $30,000, a median of $51,000, and a p75 of $90,000. Recent activity shows repeated giving to the same organizations across multiple years, especially for conservation and community groups in Orange County. The grants are framed as contributions in furtherance of recipients’ exempt purposes, which aligns with operating-style support. The foundation is not a funder of individuals and does not make program-related investments.
