As CFIO, Bancroft will continue the Foundation’s commitment to 100% mission-aligned investing that was launched and spearheaded by the current Chief Financial and Investment Officer, Tim Ortez who is retiring. Bancroft will lead the impact investment, finance and grants management teams while providing strategic counsel to the President and C.E.O., the Executive Leadership Team, and the Investment Committee of the Board of Directors.
He will build upon Ortez’s tremendous work in shaping and driving the Foundation’s mission-driven investment strategy that helped create immeasurable impact in local communities in Southern California. The Foundation is forever grateful for Tim’s leadership, his contributions, and the standard of excellence he established for its investment strategy over his nine-year tenure.
As the new CFIO, Bancroft will provide critical financial stewardship and strategy to advance the organization’s commitment to bold and creative deployment of philanthropic resources to drive economic equity and inclusion.
“I’m honored to join the Weingart Foundation and be a part of its seventy-plus year legacy of supporting communities in the fight for opportunity and justice,” said Bancroft. “From my first conversations with the team, I knew we were aligned on what matters most: listening to the people we serve, breaking down barriers, and creating real, lasting change. I’m excited to build a financial strategy that reflects those values and helps expand how we think about equity in all its dimensions.”
In his previous role as Vice President of Finance and Mission Investing for the Nathan Cummings Foundation, Bancroft led the transformation of their $450 million endowment toward a 100% mission-aligned strategy to advance racial, economic, and environmental justice. He modernized the finance and accounting function and was responsible for launching a $22 million program-related investments initiative. Bancroft graduated from Boston University summa cum laude, with a B.S. in management.
Vy Nguyen
Returning to the Foundation where she spent 15 years helping to launch the housing and immigrant justice portfolios and manage special projects, Nguyen will lead strategy development and program implementation across the Foundation. She will serve as a key architect of the Foundation’s racial and economic justice strategy, leading the co-design of its strategic initiatives, ensuring community voice and lived experience remain central to the Foundation’s work and investments.
“It’s an honor to return to the Weingart Foundation when our region is calling for bold, community-driven action,” said Nguyen. “I’ve seen firsthand the power of organizations centering equity and the lived experience of local communities. In my new role, I will help strengthen the Foundation’s community-centered strategies to create a more just and equitable Southern California.”
As CPSO, she will oversee the evolution of the Foundation’s programs, ensuring alignment across the Foundation to increase impact. Nguyen will work closely with the C.E.O., the Leadership Team, and all program areas.
Nguyen most recently served as Director of Spiritual Home at PICO California, the state’s largest faith-based organizing network. Her career spans nonprofit, philanthropic, and government sectors, including prior service as a deputy to L.A. Unified School District Board President Monica García and a decade of organizing with the Koreatown Immigrant Workers’ Alliance and the Los Angeles Alliance for a New Economy.
