As the nation’s largest donor and volunteer supported mentoring network, Big Brothers Big Sisters makes meaningful, monitored matches between adult volunteers (Bigs) and children (Littles), ages 5 through 18, in communities across the country.  We develop positive relationships that have a direct and lasting effect on the lives of young people.  We currently serve children in Park, Gallatin, Sweet Grass, and Madison counties.
