2018 Programs

  • 488 Children in Greater Chattanooga (Hamilton, Bradley & Marion counties in Tennessee and Catoosa, Dade and Walker counties in Georgia) were served through mentoring relationships.

  • 271 Community-Based matches: a volunteer "Big" and a child "Little" spend 4 - 6 hours a month participating in activities in the community or just "hanging out." (65 of these matches are AMACHI).

  • 217 Site-Based matches: the volunteer "Big" visits the child for an hour a week at the child's school or a designated after-school site--reading a book, playing a game, having lunch, talking, being friends. (30 of these matches are AMACHI).

  • 117 COUL Kids (Club of Unmatched Littles) are waiting for volunteer "Bigs" because the need and desire for mentors grows faster than our volunteer base.
