Big Brothers Big Sisters is the oldest, largest and most effective youth mentoring organization in the United States. We have been the leader in one-to-one youth service for more than a century, developing positive relationships that have a direct and lasting impact on the lives of young people.

Big Brothers Big Sisters of San Diego County serves children, ages 7 through 18, in six distinct programs:  Amachi, Bigs in Schools, Community Mentoring, High School Bigs, Operation Bigs and Sports Bigs.

Our Mentoring Works
National research has shown the positive relationships between youth and their Big Brothers and Big Sisters have a direct and measurable impact on children's lives. Little Brothers and Sisters are:

• More confident in their schoolwork performance
• Able to get along better with their families
• 46% less likely to begin using illegal drugs
• 27% less likely to begin using alcohol
• 52% less likely to skip school
