Gregg Hammerman

vice president

I became a "Big" in 2001 after hearing my father and a close friend talk about their wonderful experiences as bigs. I was fortunate to be matched with an amazing 7-year-old "Little" here in Washtenaw county. 18+ years later, we continue to be close friends. The impact that we have been able to have on each others lives is amazing and very meaningful. I'm thrilled to be a part of the Board and help in any way that I can.
