For more than 40 years, Big Brothers Big Sisters of Southwestern Illinois has operated under the belief that inherent in every child is the ability to succeed and thrive in life. As an affiliate of 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 6 through 18, in Clinton, Madison, Monroe and St. Clair counties. We develop positive relationships that have a direct and lasting effect on the lives of young people and change their lives for the better, forever.
