  • Jessica Vibberts

    Jessica Vibberts

    Interim CEO & Chief People Officer

    Jessica grew up in the rural foothills of Northern California, where only a third of her high school peers graduated college-ready. Jessica attended Sonoma State University as a first generation college student and earned her bachelor's degree in gender studies and sociology in 1999. This experience made her acutely aware and determined to make an impact on the pervasive lack of opportunities and education available to many children. After college, Jessica ran the education and community outreach department at Verity of Sonoma County, where she developed a comprehensive sexual violence prevention education curriculum for youth that is still widely used in Sonoma County schools. In 2002, Jessica joined Summer Search North Bay as a program associate and rapidly advanced to become the executive director and then national COO. Under Jessica’s leadership, Summer Search was named one of the 50 best nonprofits to work for by the Nonprofit Times for three years running. In 2007, Jessica participated in strategic perspectives on nonprofit management at Harvard Business School, and was named a Gap Inc. Leadership Fellow for three years in a row. Jessica is excited to bring her passion for growing people and her experience in entrepreneurial, high-growth nonprofits to Reading Partners.
