Overview
The Joseph A.W. Clayes III Charitable Trust was established in 2007 following the death of Joseph Clayes III, a financial and real estate investor and avocado rancher from Anaheim, California. The trust is managed by his niece, Trulette Clayes (Controller at the Museum of Contemporary Art San Diego), and Brendan Holmes (Joseph's former business partner). With assets exceeding $37 million and annual giving of approximately $1.8 million, the trust focuses on supporting children facing physical or mental challenges, performing arts, museums, and causes involving children and dogs. The trust operates as a private independent foundation and makes significant endowment gifts to carefully selected organizations primarily in Southern California.

Governance and Leadership
Trustees:
Trulette M. Clayes: Niece of Joseph Clayes III, serving as trustee since 2007. She is the Controller at the Museum of Contemporary Art San Diego (since 1998) and holds a Bachelor of Accountancy degree from the University of San Diego.

Trustee Philosophy: According to Trulette Clayes, "Education was important and the arts were important. Helping children is a strong part of our mission." She also noted about her uncle: "My uncle never had kids, but he was kind of a kid himself. Watching kids playing and being happy with their families and their pets made him happy."
Brendan Holmes stated: "Making a positive and lasting impact on children with cancer perfectly illustrates the mission of the Trust."

Application Success Factors
Since this trust does not accept unsolicited applications, organizations cannot directly apply. However, based on the trust's giving history, the following factors characterize their preferred grants:
Focus on Endowments: The trust strongly prefers making endowment gifts that provide permanent, lasting support rather than annual operating grants. Major gifts have established endowed funds, endowed chairs, and named facilities.
Children as Primary Beneficiaries: Trulette Clayes emphasized, "Helping children is a strong part of our mission." The trust's largest grants have supported children's health research, children's hospitals, and organizations serving families with critically ill children.
Named Recognition: Virtually all major grants have resulted in named recognition - research centers, theater spaces, exhibition wings, endowment funds - suggesting the trust values legacy and visibility.
Southern California Connections: All grants have been to organizations in San Diego County, Orange County, Coachella Valley, or to Joseph Clayes III's alma mater (Cal State Fullerton). Geographic proximity appears essential.
Quality Organizations with Strong Track Records: Recipients include major, well-established institutions like Rady Children's Hospital, Ronald McDonald House Charities, Cal State Fullerton, and the Museum of Contemporary Art San Diego.
Mission Alignment with Founder's Interests: Joseph Clayes III loved theater and opera, was frugal but generous, had a golden retriever, and advocated for children's health and welfare. His personal interests continue to guide trustee decisions.
