Our History at Big Brothers Big Sisters of Southwestern Illinois:

In 1979, a group of social workers from the Belleville Area Special Education District and concerned community volunteers came together to form an interest group, which became the first Board of Directors. The problem they wanted to address was the growing number of students in need of positive role models and mentors. In 1980, this group requested affiliation with Big Brothers Big Sisters of America, hired the first staff person as Executive Director, became incorporated as a non-profit organization in Illinois, and applied for tax exempt status with the IRS.

In the first year of providing service to youth facing adversity, the agency matched 35 children with mentors and served over 80 children through group activities. Since that time, thousands of children have benefited from the individual attention of a positive role model and mentor. With the support of the individuals and corporations in the community, the agency expanded services to Madison County in 1986. Services began in Clinton County in 2001 and in Monroe County in 2003. In 2015, more than 400 youth were matched with a mentor and more than 45 children received counseling services by our in-house counselor.
