The company’s franchise is anchored by a dense branch network across Washington, Oregon, California, Idaho, Utah, and Nevada, supplemented by digital banking and electronic account origination. Banner positions itself as a “super community bank,” combining local service and decision-making with the product breadth of a regional bank.
