The Buck Foundation

What The Buck Foundation does

The Buck Foundation is a private family foundation established in 1986 by Douglas Buck and Mildred Meyer Buck (Mims), headquartered in Denver, Colorado. The foundation's stated mission is to promote peace, social justice, and the prevention of climate catastrophe, with climate action added to its mandate in 2021. It operates two primary grant programs—Climate Action Grants and Peace & Social Justice Grants—alongside General Operations Support grants that provide unrestricted funding. The foundation is family-controlled, with multiple generations including children, grandchildren, and great-grandchildren serving on the Board of Directors; it employs 11-50 staff including Executive Director Erika Church and Board Chair Topher Buck.

The foundation distributes grants exclusively to qualified 501(c)(3) organizations and non-governmental agencies, primarily in Colorado (Denver Metro area), with occasional grants to organizations in board members' home communities in Montana, Indiana, and Australia. Grantmaking is proactive and invitation-only—the foundation identifies and invites potential grantees rather than accepting open applications, and has stated it is not currently accepting new Letters of Inquiry. Average grant size is $10,000-$20,000, with a 2025 grant budget of $649,000 (up from $440,000 in 2024) and cumulative grants exceeding $7.7 million since inception. The foundation maintains a limited marketing footprint, relying on its website and direct outreach to current and prospective grantees, with no disclosed technology platform, AI capabilities, or commercial revenue operations.
