The Sundheim Family Foundation directs almost all of its giving to a very small number of recipients, providing large, general-purpose grants rather than many small project awards. Its pattern suggests institutional support—likely multi-year or core operating funding—to a handful of organizations rather than broad community-level grantmaking.
Highly concentrated giving: four grants totaling about $20M, with three grants to one top recipient ($14.04M) and a second recipient receiving $5.91M. Emphasis on large, general-purpose awards and repeat support rather than many small or project-specific grants.
