Big Brothers Big Sisters of the North Bay provides adult mentors to children in need of good role models. Adults are matched to "littles" between the ages of 6 and 17 to meet each week for a variety of enjoyable activities. BBBS also has site-based mentoring at community centers and schools in the area. If you would like to become a Big Brother or Big Sister, you'll need to submit an application, talk with a counselor, and undergo a background check for safety purposes.
