Founded in 1956, OmniAmerican Bank built its business around commercial, mortgage, and personal banking services for North Texas communities. In December 2014, it merged with Tyler-based Southside Bank, and the combined institution operates under the Southside Bank name. The bank is headquartered in Fort Worth, Texas, and serves customers across the North Texas region. Today, Southside Bank is one of the larger community banks in Texas, with a broader footprint that spans North Texas, East Texas, and the Austin area. The merger expanded its lending capacity and product offerings and increased convenience through more banking locations. Recent leadership changes in 2025 include the appointment of a Chief Operating Officer.
