Multiple Generations and Perspectives Strengthen the Board

The Sobrato family’s commitment to Silicon Valley is strong – so strong that it recognized a moment when more voices would inform the Foundation’s strategic decisions. This year new board members from outside the family joined this leadership group to bring varied points of view and insight to the Foundation’s investments across the region and identify new ways to work toward impact.

Foundation board members have a history of promoting economic opportunity for all by supporting access to high-quality education, pathways to sustainable jobs and investments in social-sector leaders and high-impact nonprofits.

The Sobrato family appreciates all that the Bay Area and Silicon Valley have provided for them and wants every individual, and every family, to have the opportunity to thrive. That’s why the family invests in the place it has called home for four generations: to ensure that everyone in Silicon Valley has the opportunity to drive innovation and pursue their dreams. The family remains active on the board and in its commitment to quality education, safety-net services and career pathways.
