Big Brothers Big Sisters

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.

Each youth is matched with a carefully screened and trained volunteer adult or high school mentor, and matches typically meet once a week at school (school-based program) or in community settings (community-based program). Matches can spend their time together talking, doing homework, doing crafts, playing games or sports. In community-based matches, they also spend time doing activities in the community like attending cultural events, going to restaurants or movies, or exploring other interests.
