Guy has been representing injured clients all over Oklahoma for over 25 years. He has taken his years of experience and courtroom skills developed while working in both large and small law firms and opened the GT Law Firm, with offices in Tulsa and Oklahoma City.

Guy's main practice area is wrongful death of the elderly, with emphasis in nursing home and assisted living abuse and neglect. Guy believes how a person dies matters.

“Every person or their family member who has been injured or killed by someone’s misconduct deserves answers as to how and why it happened, and fair compensation for all of the harms and losses suffered.”
