Ideal Applicant
Established Montana-based nonprofits (education, health, arts, community services) seeking general operating support and that have an existing relationship or credible referral into the foundation's network.
Good Fit
- • Clear Montana presence or program activity in Montana.
- • Existing relationship, board-level contact, or referral from a past grantee.
- • Project or operating request in the grant size range seen ($10K–$60K).
- • Mission aligns with general-purpose support (education, health, arts, community services).
- • History of prior funding from this foundation or repeat grantee status.
Geography
Giving is heavily concentrated in Montana but includes a second state; the observed footprint is effectively state-level/regional with most dollars flowing to Montana organizations.
Recipient Variety
The latest year shows ten distinct recipients across education, health, arts and community services with seven repeat grantees and three newcomers, indicating a moderate spread for a small private foundation.
New Applicants
The foundation states it funds only preselected applicants and no public submission route is visible; although three new recipients appeared in the latest year, the explicit preselection policy and relationship pattern make entry by an unfamiliar applicant unlikely.
