Big Brothers Big Sisters believes that with the support of a caring mentor, every child has the ability to achieve his or her full potential. It is the nation’s largest donor- and volunteer-supported mentoring organization, serving a quarter-million children annually. Based in Santa Ana, Calif., the Orange County agency was incorporated in 1958 and works as a local extension of the national effort to make professionally supported, one-to-one matches between mentors (“Bigs”) and children (“Littles”) facing adversity. Together with the Inland Empire agency, which opened its doors in 2013, the local organization served more than 3,000 children in 2015 through programs that improve the odds of youth performing better in school and avoiding violence and illegal activities.
