The Slaggie Family Foundation concentrates its philanthropy on institutional support for faith-affiliated education and local health care. A small number of large gifts—often repeated to the same recipients—dominate its giving, with major multi-year investments in a Catholic high school, a Catholic university, and a regional health system. The foundation appears to prioritize sustaining educational programs, scholarships/alumni activities, and community health capacity, primarily in the foundation’s region.
A repeated pattern of large, multi-year gifts to faith-based schools and a regional health system defines the Slaggie Family Foundation’s recent giving. Cotter High School in Winona received some of the foundation’s largest support, including $2,089,987 in 2023, $636,039 in 2024, and $1,566,500 in 2025. NCH Healthcare System in Naples also received a $2,000,000 general-support grant in 2023. Those awards sit alongside sustained funding for Catholic and Jesuit education, with Marquette University, Saint Benedict Classical Academy, and Saint Sebastian’s School each appearing in the recent grants list. The foundation’s grantmaking also reaches community institutions in Winona, including Winona Volunteer Services, Habitat for Humanity Winona, and Winona Community Foundation. Across the recent record, the Slaggie Family Foundation appears to favor organizations with recurring program or operating needs rather than one-time project grants, and its largest gifts tend to be concentrated in a small number of grantees over multiple years.
Catholic secondary education is a clear priority. Cotter High School received $1,566,500 in 2025 for general support, following earlier grants of $2,089,987 in 2023 and $636,039 in 2024. The foundation also backed Catholic Schools Center for Excellence with $160,000 in 2025 and $130,000 in 2024. In postsecondary support, Marquette University received $250,500 in 2024 for communications, scholarship, alumni event work, and similar grants of $250,000 in both 2025 and 2023. The foundation also supports local services for children and families. Winona Volunteer Services received $155,000 in 2024 and $150,000 in 2025 for the children’s backpack program and annual fund drive. Habitat for Humanity Winona received $90,000 in 2024 for general support, and Winona Community Foundation received $51,000 in 2025. Health-related giving appears in both medical and community settings. Children's Hospital of Wisconsin received $110,000 in 2025 and $100,000 in 2023 for general support.
The Slaggie Family Foundation’s typical grant size is $2,000 at the 25th percentile, $6,500 at the median, and $25,000 at the 75th percentile. That spread sits below the very large awards that recur at the top of the list, showing a pattern of many modest grants alongside a few major commitments. The recent record also shows repeat recipients across multiple years, especially in education and health care, indicating ongoing relationships rather than one-time support. The foundation is a regular funder, and it also funds individuals, while making no program-related investments.
