Ideal Applicant
Small to mid-sized charities that fit the foundation's past giving profile—healthcare institutions, religious parishes, community organizations, museums, or scholarship/education recipients—and that can be put forward through a recommendation or existing relationship.
Good Fit
- • Work in healthcare or hospitals (e.g., peer example: Mayo Clinic-sized grant).
- • Religious parish or faith-based community organization in the regions previously funded.
- • Local community nonprofits, museums, or senior/community center programs in the states seen in past giving.
- • Capacity to accept general operating support and be recommended by a trusted intermediary.
Geography
Giving in the observed years covered six states rather than a single city or county, so the footprint is multi-state; however a single large Minnesota grant accounted for the majority of dollars.
Recipient Variety
The latest year shows 13 distinct recipients with eight new grantees and five repeat recipients across two years, indicating a fairly broad set of independent beneficiaries despite dollar concentration in a few large grants.
New Applicants
The foundation indicates grants are by preselection only and no public application route or contact details were found; while many new recipients appear in the latest year, the preselection model and lack of public submission routes make unsolicited entry unlikely.
