Big Brothers Big Sisters of the Bay Area has been providing Bay Area youth with professionally supported one-to-one mentoring relationships in San Mateo, Santa Clara, San Francisco, Alameda, and Contra Costa counties since 1958. As the nations largest donor and volunteer supported mentoring network, Big Brothers Big Sisters makes and monitors meaningful matches between adult volunteers (Bigs) and children (Littles), ages 6 through 18, in communities across the country. We develop positive relationships that have a direct and lasting effect on the lives of young people.
