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?

You can help by…

Real stories.
