The Margaret R Seeley Charitable Foundation concentrates its giving on conservation and animal welfare, splitting support between national park/land preservation and local San Diego environmental and humane organizations. Grants tend to be relatively large and targeted, with repeat support to a few organizations rather than broad, small-dollar distribution. The foundation combines national-scale conservation (National Park Foundation and its lands initiative) with place-based giving in San Diego (humane society and botanic garden).
Margaret R Seeley Charitable Foundation gives at a relatively focused scale, with grants clustered around conservation, animal welfare, and a smaller set of cultural and social-service causes. The largest recent award in the file is $50,000 to the National Park Foundation in 2024 to preserve national parks, followed by repeated support for the same conservation and humane groups across 2023 and 2024. That pattern shows a funder that concentrates on a few organizations rather than broad, one-time giving. National park preservation is one of the clearest threads. The foundation supported the National Park Foundation in both Baltimore and Washington, DC, and also backed Cabrillo National Monument Foundation in San Diego. Animal welfare is another major line of giving, with recurring grants to San Diego Humane Society, Rancho Coastal Humane Society, Lions Tigers & Bears Big Cat and Exotic Animal Rescue, and Helping Homeless Felines. The portfolio also includes support for San Diego Botanic Garden, Oceanside Museum of Art, Mingei International Museum, Planned Parenthood Federation, and UCSD Library.
Conservation is the most visible theme in the grant record. In 2024, the foundation gave $50,000 to National Park Foundation for preserving national parks, after a $25,000 grant in 2023 to the same organization for the same purpose. It also gave $25,000 in 2023 to National Park Foundation Lands Initiative to preserve national parks, and $5,000 in both 2023 and 2024 to Cabrillo National Monument Foundation to support the national park. Animal welfare is another sustained area. San Diego Humane Society received $25,000 in 2023 and again in 2024 to help animals in need. The foundation also supported Rancho Coastal Humane Society with $15,000 in both 2023 and 2024, and gave multiple grants to Lions Tigers & Bears Big Cat and Exotic Animal Rescue for helping animals in need. Beyond animals, the record includes $25,000 to Planned Parenthood Federation in 2024 for reproductive healthcare and $10,000 to UCSD Library in 2023 for literary materials.
Typical grants are tightly grouped: the 25th percentile, median, and 75th percentile are $10,000, $10,000, and $15,000. That points to a grant program built around standard award sizes, with occasional larger gifts such as the $50,000 conservation grant. The record also shows repetition: several recipients appear in both 2023 and 2024, including National Park Foundation, San Diego Humane Society, Rancho Coastal Humane Society, Lions Tigers & Bears Big Cat and Exotic Animal Rescue, Helping Homeless Felines, Oceanside Museum of Art, Aspca, Planned Parenthood Federation, San Diego Botanic Garden, and Cabrillo National Monument Foundation. The foundation is a private charitable foundation and does not make program-related investments or grants to individuals.
