The Gallo Foundation concentrates its philanthropy into a small number of sizable gifts, split primarily between global conservation work and biomedical/academic medicine. Its giving is highly concentrated: multi-hundred-thousand to million-dollar grants made repeatedly to a few institutional partners, indicating long-term relationships with organizations that run large-scale science and research programs.
The David E & Mary C Gallo Foundation’s recent giving is defined by two recurring anchors: Conservation International and Johns Hopkins University. Those relationships point to a funder that makes large, repeat support to a small set of institutional partners rather than spreading dollars broadly. In 2025, the foundation gave $650,000 to Conservation International for general support and $480,000 to Johns Hopkins University for general support; the prior year, it gave $600,000 and $960,000 respectively, including a Department of Medicine grant to Johns Hopkins. Beyond those flagship gifts, the foundation also supports biomedical and academic medicine through the Johns Hopkins University Department of Medicine and broader university-based funding. Its portfolio includes general support for major nonprofits as well as institutional support for departments and organizations, which is consistent with a grantmaker that favors established entities with scale. The recent grants list also shows smaller awards to California community organizations, faith-based institutions, and education-related entities, suggesting that the foundation combines a concentrated large-grant program with a narrower set of local and institutional commitments.
Global biodiversity and ecosystem conservation is one clear priority. The foundation gave Conservation International $650,000 in 2025, following $600,000 in 2024 and $525,000 in 2023, all for general support. Biomedical and academic medicine is another major theme. Johns Hopkins University received $480,000 in 2025 for general support, while the Johns Hopkins University Department of Medicine received $960,000 in 2024 and The Johns Hopkins University Department of Medicine received $200,000 in 2023. The foundation also funds community-serving and faith-based organizations. It gave United Samaritans Foundation $80,000 in 2024 and $70,000 in 2025 for general support, and supported Franciscan Friars of the Atonement with both general and religious support across multiple years.
The typical grant size is $1,500 at the 25th percentile, $5,000 at the median, and $18,750 at the 75th percentile, though the recent record also includes much larger institutional awards. The pattern is relationship-based: Conservation International, Johns Hopkins University, United Samaritans Foundation, Kvie Inc, and Franciscan Friars of the Atonement each appear in multiple years. The foundation does not fund individuals and does not make program-related investments. Its grants are mainly institutional support and general support, with some educational and religious support mixed in.
