BOK Financial, also known as the Bank of Oklahoma, has been serving customers since 1910. More than a century later, it now commands over $40 billion in assets.

BOK Financial is open from 9 a.m. to 4 p.m. on weekdays, which is fairly standard for banks. The drive through service is open longer, from 9 a.m. to 6 p.m.

Some BOK Financial branches are closed on Saturday and Sunday. Below is an overview of BOK Financial’s business hours.
