Crystal CallahanHere at SIS Bank, we don't believe in phone automation, nor the "if you know your party's extension, dial it now" routine. We have a live person answering the phone during business hours so you can get the proper assistance you deserve. Meet Crystal, our phone operator and Main Office receptionist. She'll point you in the right direction!
