Brett A Chapman, Attorney at Law
Brett’s ancestor Chief Standing Bear made history as the first Native American to win civil rights in his landmark 1879 case Standing Bear v. Crook that established that Native Americans are persons entitled constitutional rights under the law, a pivotal moment in the fight for Indigenous rights.
Inspired by his ancestor’s legacy, Brett practices law in Tulsa, focusing on criminal defense and forwarding Native American rights. He represents clients across the Tulsa metro area and throughout Eastern Oklahoma, advocating for justice with the same unwavering determination that defined Standing Bear’s fight for equality.
