Banner Bank traces its corporate lineage back to its founding as a traditional community financial institution known as First National Bank of Commerce in southeastern Washington. Over the course of the late twentieth century, the bank expanded its operational footprint significantly through a series of strategic mergers, acquisitions of neighboring community banks, and cross-border expansion into Oregon, Idaho, and California. To better reflect its unified regional identity and broader economic reach across the Pacific Northwest rather than a single municipality, the holding company and its banking subsidiary transitioned their brand name to Banner Bank. This corporate renaming accompanied a comprehensive modernization strategy, enabling the institution to grow into a major regional commercial bank while preserving its relationship-driven community banking philosophy.
