Big Brothers Big Sisters has been the nation's pre-eminent youth mentoring organization for over 100 years. We have proven success in creating and nurturing positive relationships that benefit everyone involved, including the volunteer, the child, families, and the community. Through our programs, each year over 350 children in Clinton, Eaton, Ingham, Ionia and Shiawassee Counties have the opportunity to have an adult friend and positive role model in their lives.
