Big Brothers Big Sisters – Bay Area

Our mentoring has a proven long-lasting, positive effect on kids’ self-esteem, academic achievement, and relationships with family and peers.





We serve kids between the ages of 6 – 18 in all nine Bay Area counties.

Many of our kids are from single-parent homes or live with a non-parent caregiver. Many live below the poverty level, with caregivers struggling to be an active presence while providing financial necessities for their family. Exposed to greater adversity such as elements of gang activity, substance abuse, and crime, they have the potential for greatness but need a special role model and friend they can trust. We are a lifeline for these kids, by providing a special match to help them realize their potential.

This traditional program matches screened adult mentors (Bigs) with enrolled children (Littles) on a one-to-one basis. This program requires a one year commitment and the matches meet several times per month.

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 – 18, in communities across the country to develop positive relationships that have a direct and lasting effect.

Big Brothers Big Sisters of the Bay Area has been providing Bay Area kids 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 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, we merged with Big Brothers Big Sisters of the North Bay, which had been serving children in Marin, Sonoma, Napa and Solano Counties since 1970, to further streamline resources. 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.
