Mission & Focus Areas

The foundation does not publicly disclose a formal mission statement. However, tax filings and grantmaking patterns indicate primary funding focus in the following areas:

  • Education (K-12 and higher education)
  • Arts and Culture
  • Democracy and International Affairs
  • Health
  • Jewish Causes

The foundation prioritizes institutions with which the Wachenheim family maintains personal connections, often through board memberships and long-term relationships.

Grantmaking

The foundation does not accept unsolicited applications. Grantmaking decisions are made at the discretion of trustees based on family interests and board connections. The foundation operates through trustee-directed grantmaking rather than formal grant programs. It is challenging to contact the foundation except by mail, and the foundation takes a proactive rather than reactive approach to grantmaking.
