Southwest State Bank

Southwest State Bank was established on April 4, 1911, under the original name of The First National Bank of Sentinel. Over the years, the institution underwent several changes, notably on July 1, 1970, when it changed its name to Southwest State Bank and transitioned to state chartering while withdrawing from membership in the Federal Reserve System. The main office of the bank was relocated multiple times, with a move to Main Street in Sentinel, Oklahoma, in April 1990, and later to 122 East Main Street in Sentinel on June 1, 2010. Ultimately, on June 28, 2015, Southwest State Bank merged with All America Bank, based in Oklahoma City, Oklahoma, marking the end of its independent operations.
