Executive Director

I joined BBBSG in the summer of 2013 and I am thrilled to continue to work for, and be a part of, such a strong organization, with an amazing collection of stakeholders and community partners. The response from the local community to our mission has been truly impactful and I look forward to continuing to build on these relationships and establish new ones, too. The BBBSG movement offers something for everyone and I enjoy hearing stories from partners and providing them with opportunities to get involved. I’m a proud husband to Jill and father to Abigail, and in my free time, you can find me attending sporting events, listening to music and spending time with family and friends.
