About William T.
William T. Mayo pursued advanced legal study early in his career, earning a J.D. from Southwestern University School of Law in 1980 and an LL.M. from Boston University School of Law in 1981. His law school record shows an emphasis on criminal defense, reflected in course work and practical training during that period. The two degrees provided both courtroom preparation and an opportunity for broader legal study at the graduate level.
After completing his formal legal education, Mayo entered the practice of law and over the decades has concentrated on criminal defense. He has worked through the ordinary rhythms of criminal practice: pretrial motions, evidentiary hearings, client counseling and trials. He has seen how cases evolve from initial arrest through adjudication. Those practical experiences have shaped the way he evaluates risk and prepares for courtroom work.
Mayo's approach is straightforward. He examines factual records, tests legal theories, and prepares clients for the steps ahead. He favors clear explanations over legal jargon. He reads records carefully and communicates options plainly. Colleagues and clients have found that methodical preparation matters in tense courtroom settings. That preparation often determines whether a case resolves early or requires a full trial.
Over the course of more than four decades in legal practice, Mayo has handled a range of criminal matters. He has navigated cases that required immediate intervention and others that moved slowly through appeals and post-conviction procedures. He has also participated in plea negotiations when a negotiated outcome made sense for a client. His work has taken him into courtrooms and into meetings with prosecutors, judges and defense teams.
Today Mayo continues to practice law, drawing on his J.D. and LL.M. training and long years of courtroom work. He represents individuals accused of crimes and advises them on procedural and strategic choices that shape a case from start to finish. He remains active in criminal defense practice and represents clients in criminal matters as of 2026.
