Eric is one of the Center for Social Sector Leadership’s newest team members, but he joins the Berkeley Haas community with years of experience in the field of advocacy work and civic engagement. Since 2014, Eric served on the City of Fairfield Youth Commission; for many of those years, he also served as the Chairman for the Commission. Beyond the Youth Commission, Eric has worked with nonprofit organizations, such as the Solano Children’s Network, to ensure that the voices of youth in the community are amplified.

From this position on the governing board, to other advisory bodies within the school district, to representing Assemblymember Tim Grayson in the field, Eric has used his leadership positions to ensure that the voices of his fellow community members are just as heard as his own.
