Cornerstone Bank is proud to be a part of the unique cultures of the Oklahoma communities in which we serve. Cornerstone’s family of employees not only works and lives in these communities, but has a long history of supporting the people and organizations in Watonga, Geary, and Mustang with not only our dollars, but also with many hours of support and volunteerism. In addition to these communities we will soon be serving the west Oklahoma City, Yukon and Bethany area. This page of our website is dedicated to our communities and the contributions our employees and local citizens are making in our efforts to be the “Cornerstone” of our communities”.
