Kirkpatrick Bank is headquartered in Edmond, Okla., serving Oklahoma and Colorado with branches in Edmond, Oklahoma City and Colorado Springs. Originally chartered as American Bank and Trust in 1970, the bank was acquired by the Kirkpatrick family in 1988, a troubled year for many Oklahoma banks. In the same year, the Kirkpatrick family proposed and backed, with the support of other Oklahoma financial leaders, a plan to recapitalize Liberty National Bank.
