Columbia Banking System, Inc. was a bank holding company headquartered in Tacoma, Washington, providing a wide range of banking services to individuals and businesses. In March 2023, Columbia Banking System completed its merger with Umpqua Holdings Corporation, the parent company of Umpqua Bank. The combined entity now operates under the Umpqua Bank name and brand, headquartered in Lake Oswego, Oregon. This strategic merger created a leading West Coast bank with an expanded footprint and enhanced service capabilities, serving communities across Oregon, Washington, California, Idaho, Nevada, Utah, Arizona, and Colorado. Information provided largely reflects the current state of the merged entity, Umpqua Bank.
Serves as the primary corporate headquarters for Umpqua Bank, overseeing strategic direction, administrative functions, and core banking operations for the combined organization.
The Umpqua Bank Plaza in Lake Oswego is a modern campus designed to support a collaborative and innovative work environment. It features contemporary office spaces and amenities.
Umpqua Bank promotes a work culture centered on customer service, community involvement, and associate empowerment. The integration with Columbia Banking System aimed to blend the strengths of both cultures, fostering a people-first approach.
The Lake Oswego headquarters symbolizes the unification of two significant Pacific Northwest financial institutions, marking a new chapter as a larger, more diversified regional bank.
Umpqua Bank, incorporating the former Columbia Banking System, operates primarily within the United States, with a strong presence across the Western states: Oregon, Washington, California, Idaho, Nevada, Utah, Arizona, and Colorado. It does not maintain physical branches or dedicated offices internationally but supports its domestic customers' international banking needs through correspondent banking relationships and standard international transaction services.
