The Hadley & Marion Stuart Foundation concentrates its giving in large, targeted gifts primarily to higher education and independent secondary schools, with a clear preference for supporting institutions rather than small community organizations. Grants are often multi-award and repeat commitments, with a geographic tilt toward Colorado (CSU, University of Colorado) while also supporting selective private colleges and specialty causes like animal health and paralysis research. The foundation funds institutional general operating or capital priorities rather than project‑level microgrants.
A defining feature of the Hadley & Marion Stuart Foundation is its willingness to make very large, repeated commitments to a small set of institutions. The largest recent grants go to Colorado State University through the CSU Foundation, including multiple awards in the seven-figure range across 2023, 2024, and 2025. Sweet Briar College also appears as a major recipient over multiple years, showing that the foundation’s support is not limited to one institution or one year. Its grantmaking favors organizations with established institutional structures rather than small, one-off projects. The pattern includes public universities, a private liberal arts college, an independent preparatory school, and specialized nonprofits working in animal health and paralysis research. Marianapolis Preparatory School received repeated support at the million-dollar level and beyond, while the University of Colorado Foundation appears among the Colorado higher-education recipients. The foundation also backs mission-specific groups such as Morris Animal Foundation and Conquer Paralysis Now, indicating a mix of education-centered giving and selective support for medical and animal-related causes. Across the recent record, the foundation’s gifts are typically sizable, multi-year, and directed to organizations capable of using unrestricted or broad charitable support.
Higher education is a central theme in the foundation’s grantmaking. It gave $1,833,500 in 2024 to the CSU Foundation for general charitable purposes, and the same recipient received $1,775,000 in 2023 and $1,750,000 in 2025. Another Colorado higher-education recipient, the University of Colorado Foundation, received $1,000,000 in 2024. Independent schools are another clear focus. Marianapolis Preparatory School received $1,000,000 in 2023, $1,000,000 in 2024, $750,000 in 2024, and $600,000 in 2025. The foundation also made multi-year support to Sweet Briar College, including $1,500,000 in 2023 and $1,200,000 in 2024. Beyond education, the foundation supports specialized charitable work. Morris Animal Foundation received $550,000 in 2025 and $510,000 in 2024, while Conquer Paralysis Now received $500,000 in 2024 and $500,000 in 2025.
Typical grants are large: the distribution is $25,000 at the 25th percentile, $75,000 at the median, and $150,000 at the 75th percentile. The recent record shows repeated support to the same recipients over multiple years, especially in higher education and independent schools. That includes multi-year awards to CSU Foundation, Sweet Briar College, Marianapolis Preparatory School, Morris Animal Foundation, and Conquer Paralysis Now. The foundation does not fund individuals and does not make program-related investments. The grants shown are broad charitable awards rather than narrowly specified project microgrants.
