Dr. Carr and Kim Donnelly

This is a family business. We have a lot of pride in what we do. GSB makes me feel like they understand that. And they value it, too. When I got my first loan from GSB, they worked incredibly hard to get me the terms I wanted. Now, years later, they still drop in just to see how I’m doing. I know they believe in my business, and that makes me feel good.
