The Alonzo Mather Foundation Trust concentrates its philanthropy almost entirely on a single organization, providing unrestricted general operating support. Grants are education-classified and routed to The Mather Foundation, suggesting the trustee prioritizes sustained institutional funding for that flagship entity rather than a diversified portfolio. The foundation appears locally focused (Grayslake/Chicago area) and oriented toward long-term stability of one core grantee.
Highly concentrated: very large, repeat grants directed to one primary grantee; no evidence of diversified or small-scale giving.
