WOLF CREEK CHARITABLE FOUNDATION concentrates almost all of its giving into a very small number of large, research-focused awards. Half the foundation’s documented grants support medical research into chronic lymphocytic leukemia and the other half fund avian population science at Cornell, suggesting a preference for scientific, project-directed philanthropy rather than broad community support. Grants are sizable, restricted to specific centers or programs, and made repeatedly to the same recipients.
Wolf Creek Charitable Foundation C/o Baldwin Family Office stands out for concentrating major grants into a small set of scientific and conservation commitments. Its documented giving is built around repeated support for chronic lymphocytic leukemia research through CLL Global Research Foundation and avian population science through Cornell Laboratory of Ornithology’s Center for Avian Population Studies. Those two lines of work appear across multiple years and at multi-million-dollar levels, indicating a preference for long-running, project-directed funding rather than broad, one-time community philanthropy. The foundation also extends this pattern into wildlife and habitat-related work. Recent awards include support for The Peregrine Fund, The Raptor Center, American Bird Conservancy, Island Conservation, and Hawk Mountain Sanctuary Assoc, alongside grants tied to specific sanctuary and restoration projects such as Fares. In human health, St Jude Children's Research Hospital and Shriners Hospital for Children appear among the larger recipients, while Gary Sinise Foundation and several Wyoming-based organizations show a separate stream of regional support. Across the record, the foundation gives at levels that are substantial enough to underwrite centers, restricted programs, and named projects.
In biomedical research, the foundation made a $2,000,000 unrestricted grant to CLL Global Research Foundation and also gave the same recipient $1,500,000 in 2023, showing sustained support for chronic lymphocytic leukemia work. In bird science, Cornell Laboratory of Ornithology received $2,000,000 in 2024 and $1,500,000 in 2023 for the Center for Avian Population Studies, plus another $2,000,000 unrestricted grant in 2025. Wildlife conservation is another clear thread. The foundation gave $250,000 and $200,000 to American Bird Conservancy, $150,000 and $100,000 to The Peregrine Fund Inc, and $100,000 to The Raptor Center. Habitat-oriented giving also appears through Island Conservation and Hawk Mountain Sanctuary Assoc, while Fares received multiple $200,000 grants tied to Incubator Basin and El Mirado Sanctuary Preservation. Wyoming-linked support includes Sheridan Co Memorial Hospital Fdn, The Brinton Museum, and Wy Stock Growers Agricultural Land Trust.

Highly concentrated: very few (6) grants totaling $11M, split between two repeat grantees; large, restricted gifts targeted to specific research centers rather than many small awards.
Notable grantees: CLL Global Research Foundation, Cornell Laboratory of Ornithology — Center for Avian Population Studies, Baldwin Family Office (fiscal/administrative contact)
Typical grants are tightly clustered around smaller awards: the 25th percentile is $5,000, the median is $10,000, and the 75th percentile is $25,000. That said, the documented recent grants also show very large project awards at $2,000,000 and $1,500,000, so the distribution is highly uneven. The recipient list repeats across years, especially for CLL Global Research Foundation, Cornell Laboratory of Ornithology, Gary Sinise Foundation, American Bird Conservancy, Fares, and Island Conservation. That pattern points to multi-year relationships rather than one-off gifts. The foundation makes grants only and does not fund individuals or program-related investments. The legal name places it under Baldwin Family Office.
Grantmaking is national, with recipients in 100% U.S. locations. By count, Wyoming appears most often, even though the headquarters is in West Conshohocken, Pennsylvania; Pennsylvania recipients account for 3% of grants. Recent examples in Wyoming include Sheridan Co Memorial Hospital Fdn, The Brinton Museum, and Wy Stock Growers Agricultural Land Trust. Outside Wyoming, the foundation’s larger recipients cluster in Houston, Greenwich, Memphis, Los Angeles, Boise, and Santa Cruz, showing a nationwide spread tied to specific institutions and projects.
Its documented giving centers on research and conservation organizations, especially chronic lymphocytic leukemia research and avian population studies. Recent recipients also include hospitals, military-family support, museums, land trusts, and sanctuary or restoration groups such as St Jude Children's Research Hospital, Gary Sinise Foundation, and Island Conservation.
Yes. The grant history shows repeated awards across multiple years to CLL Global Research Foundation, Cornell Laboratory of Ornithology, Gary Sinise Foundation, American Bird Conservancy, Fares, and Island Conservation. Some of those repeats are at multi-million-dollar or multi-hundred-thousand-dollar levels.
The distribution is small at the center but includes very large outliers. The 25th percentile is $5,000, the median is $10,000, and the 75th percentile is $25,000. Recent grants also include awards of $2,000,000, $1,500,000, and $500,000.
Giving is national, with all documented recipients in the United States. Wyoming is the top state by grant count, while Pennsylvania represents 3% of grants. Recipient cities in the record include Houston, Greenwich, Memphis, Los Angeles, Boise, and Sheridan.
