Blue Sky Bank was originally chartered in Osage County, Oklahoma, in 1905 as the Bank of Commerce in Pawhuska. Since then, it has grown and undergone several name changes, including the National Bank of Commerce, NBC Bank, and most recently, CitizensBank of Oklahoma. Although the name has evolved over time, Blue Sky Bank is—and has always been—Oklahoma-Owned.
While maintaining its roots in Pawhuska, the Bank grew first to Midtown Tulsa in 2004 and then expanded into Cleveland, Oklahoma in 2014.
Recognizing its strong niche in commercial lending and community banking, and after gaining recognition for being a Bank with infinite possibilities and creative solutions for its customers, Citizens Bank was renamed Blue Sky Bank on November 1, 2016.
In 2018, Blue Sky Bank purchased Bank of Cushing, now a branch of Blue Sky Bank, Pawhuska. This acquisition added two branches to the Blue Sky Bank family.
In early 2021, Blue Sky Bank expanded into San Antonio, Texas, with the opening of its seventh branch, representing Blue Sky Bank’s dedication to serving entrepreneurs and their local businesses throughout the Southwest. Also in 2021, Blue Sky Bank announced a merger with The American Bank of Wagoner. This acquisition allowed Blue Sky Bank to continue its growth trajectory and expand its commitment to serving more Oklahomans.
In 2022, the Bank experienced substantial growth through its expansion into the Texas markets by opening loan production offices in Dallas and Fort Worth. In the fall of 2022, the Bank acquired the Fairfax branch from Security State Bank. Fort Worth converted to a full branch in 2023, and Dallas followed in 2025. In December 2022, the Bank completed the acquisition of First National Bank and Trust of Weatherford, expanding its presence into five additional communities, including Cordell, Hinton, Morrison, and Stillwater.
