Brett Chapman
Brett Chapman is a highly experienced Oklahoma attorney who combines his comprehensive knowledge of Oklahoma law with a passion for justice that finds its roots in his unique family history.
Brett’s maternal great great great grandfather Chief White Eagle was the hereditary chief of the Ponca during the illegal Ponca Trail of Tears in 1877. His ancestor's against-all-odds fight for justice inspired him to become an attorney and seek justice for others.
Brett started his legal career by serving seven years in the District Attorney's Office, where he handled every kind of case possible, from misdemeanors to homicides. He also successfully changed Oklahoma's DUI case law as a prosecutor in 2015 by advocating for the change in a comprehensive legal briefing which persuaded the state's highest appellate court to change the law. See Alba v. State, 2015 OK CR 2, 341 P.3d 91.
Upon leaving the District Attorney's Office, he became a defense attorney for the Union Pacific Railroad Company and the BNSF Railway Company and defended both companies in complex wrongful death cases. His practice is now focused on criminal defense and advocating for Native American rights and tribal sovereignty in the spirit of his ancestors.
