Role models change lives 

In a world of causes, we make a difference by creating professionally supported, one-to-one matches for kids to realize their full potential. Our youth mentors are more than just volunteers--they’re heroes. Together, we clear the path to a child’s Biggest possible future by empowering them to pursue their dreams.

During a time when small choices can make a Big impact in a child's future, there is no better time to provide life changing mentorship than now.

Dozens of kids are waiting for a match right here in Southwestern Illinois. Will you help us end their wait?


A Science-Based Model

Studies show our one-to-one youth mentoring impacts children's lives by keeping them in school, out of trouble and on a path to post graduate success

We don't just trust that our programs have a big impact--we strive to constantly learn and grow from independent research and partnerships. Our commitment to continuous learning, improvement, and research is at the heart of what we do.


Showing up is a Big deal 

Research shows that the presence of a caring adult role model in a child’s life is one of the single most important factors in building a child’s resilience. Our Bigs and Littles share everyday activities together: eating out, playing sports, attending events, going to the movies, sightseeing, and just hanging out. But what matters most are not the activities. It’s the fact that these children have someone in their life they can confide in and to look up to.

There are many ways to support the mission. How will you show up to help kids reach their full potential?
