Born and Raised Oklahoman. Husband. Father. Tribal Supreme Court Justice. Trial Lawyer. Litigator. Super Lawyer. Administrative Law Judge. AmeriCorps Volunteer. Son of a Prison Warden. These are some of the titles and roles that have defined Colby’s personal and professional career.

Underneath the titles exists a personal and professional philosophy that drives him each day: lean into helping others each day through passion, care, and humility.

As an experienced trial lawyer and litigator, Colby is proud to say that he has successfully advocated for his clients over the years and secured millions of dollars in settlements and verdicts.
