Columbia Banking System is a regional bank holding company that expanded across Washington, Oregon, and Idaho through acquisitions and now operates the combined bank under the Umpqua Bank brand after merging with Umpqua Holdings. Customers access traditional banking services—deposit accounts and loans—through branches, online, and mobile channels, with local relationship banking supported by a larger regional network. The company differentiates itself by blending a broad Pacific Northwest footprint with a community-bank focus, preserving local ties while leveraging scale from the merger and rebrand. Its goal is to serve local individuals and businesses with accessible banking and loans while growing its reach and capabilities through acquisitions and the Umpqua Bank platform.
