About Us About Us

OSBOklahoma State Bank (OSB) was chartered in Mulhall, Oklahoma in 1909. Today, we have three locations that serve central Oklahoma. Branch locations include Norman, Guthrie, and Mulhall.  A loan production office was opened in Oklahoma City’s Midtown District in 2016. Our Bank came under its current ownership in July 2012 with a focus on growth strategies that include personalized authentic banking relationships with our customers. In March 2013, OSB expanded its footprint to better serve central Oklahoma with the opening of its branch in Norman. Through strategic planning under the new ownership, our Bank has seen tremendous growth and success. Furthermore, our Bank prides itself on having the best bankers in the industry to serve our clients.
