CEI Loans

At GSB, we specialize in helping business owners find financing solutions that work for them. If a traditional loan isn’t an option for your business, a CEI loan may be a good alternative. CEI (Coastal Enterprises, Inc.) is a local community development financial institution that partners with GSB to help fulfill the financing needs of entrepreneurs. Let’s work together to find a way forward.



Your success in business creates a ripple effect. Good things happen for your business, your neighborhood, and your community. It’s the kind of thing we can all believe in. So, when someone shares their vision, we do everything in our power to help them succeed. By partnering with CEI, we’re able to offer more people more opportunities to succeed. It’s a win-win-win.
