The Big Brothers Big Sisters Mission:
To provide children facing adversity with strong and enduring, professionally supported 1-to-1 relationships that change their lives for the better, forever.
The Big Brothers Big Sisters Vision:
That all children achieve success in life.
Changing Perspectives. Changing Lives.
For more than 100 years, Big Brothers Big Sisters has operated under the belief that inherent in every child is the ability to succeed and thrive in life. As the nation’s 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.
In the Bay Area
Big Brothers Big Sisters of the Bay Area has been providing Bay Area youth with professionally supported one-to-one mentoring relationships since 1958, gradually growing to represent all of the Bay Area regions, at large.
With the first major Bay Area merger in 2006, three separate Big Brother Big Sister Bay Area organizations -- San Francisco & Peninsula, East Bay, and Santa Clara County -- integrated into Big Brothers Big Sisters of the Bay Area to more efficiently serve the community and meet the increasing demand for services.
In 2017, Big Brothers Big Sisters of the Bay Area merged with Big Brothers Big Sisters of the North Bay, which had been independently serving children in Marin, Sonoma, Napa and Solano Counties since 1970, to streamline resources further, effectively reaching the entire Greater Bay Area. As a unified organization, we now serve children from nine counties in the Greater Bay Area: Alameda, Contra Costa, Marin, Napa, Santa Clara, San Francisco, San Mateo, Solano, and Sonoma.
Headquartered in San Francisco, the organization has local offices in Oakland, Milpitas, San Rafael, and American Canyon. In addition to maintaining the dedicated services of more than a thousand volunteers who serve as mentors, Big Brothers Big Sisters of the Bay Area employs over two dozen staff members who identify and support our matches in all nine counties.
