The Greenside Foundation concentrates its modest philanthropic resources exclusively on reproductive health and rights, providing general operating support to Planned Parenthood. All recorded giving is directed to a single organization across multiple grants, indicating a focused commitment to family planning and reproductive healthcare. The foundation appears to prioritize sustaining core operations of this service provider rather than funding a broad portfolio of causes.
Highly concentrated and repeat giving: small-to-midsize unrestricted grants directed solely to one grantee (Planned Parenthood) across multiple payments rather than diversified or many small recipients.
Notable grantees: Planned Parenthood
Greenside Foundation C/o Gary Vandeweghe shows a clear pattern of funding a single core mission: reproductive health and rights through general operating support to Planned Parenthood. The foundation’s recent records also show that this support is sustained over multiple years, with grants to Planned Parenthood in 2023, 2024, and 2025. That same operating-support approach appears across its other gifts as well, which are modest in size and aimed at keeping recipient organizations running. Beyond Planned Parenthood, the foundation’s recent grants include recurring support for Camp Del Corazon and Silicon Valley Independent Living Center, as well as gifts to organizations connected to education, media, theater, and golf. The portfolio suggests a local and regional grantmaker that uses unrestricted funding to cover day-to-day organizational needs rather than project-specific awards. The foundation’s giving is concentrated in California, with many recipients in San Jose, San Francisco, Oakland, San Diego, and other parts of the state. Across the recent grants list, every recorded recipient is in the United States, and the foundation’s largest recent grants reach the $12,000 level.
In reproductive health, Greenside Foundation C/o Gary Vandeweghe gave $12,000 to Planned Parenthood in 2025 for general operations. That same purpose appears in prior years, showing ongoing operating support rather than a one-time project award. The foundation also supports services for people with disabilities and children. It gave $7,500 to Silicon Valley Independent Living Center in 2023 for general operations, then renewed that support with $5,500 grants in both 2024 and 2025. For youth and family services, it made general-operating grants of $8,750 in 2024 and $8,000 in 2025 to Camp Del Corazon. Education and institutional support appear in smaller gifts as well. The Child's Primary School received $7,000 in 2023 and $6,000 in 2024, while The Bishop's School received $2,500 in 2025.
Typical grants are small: the 25th percentile is $500, the median is $1,000, and the 75th percentile is $1,500. The recent list still includes a few larger awards, including several at $8,000 to $12,000, which points to a core of many modest grants with occasional higher support. The same recipients appear across multiple years, especially Planned Parenthood, Camp Del Corazon, Silicon Valley Independent Living Center, Grid Alternatives, North Coast Repertory Theater, The Zlac Foundation, and Dartmouth College Fund. That repetition indicates recurring support rather than isolated awards. Greenside Foundation C/o Gary Vandeweghe is classified as a regular funder, and the grants shown are general operating support.
