G. Thayer Williamson Your Drug Crime Attorney

Attorney G. Thayer Williamson

Attorney G. Thayer Willamson

My legal career has been the culmination of numerous areas and roles in law that amounts to an exceptional ability to represent my clients who are facing criminal drug crimes. Early on, as a legal researcher, I excelled in finding and implementing relevant case law. Soon following, I worked my way into the role of Assistant District Attorney, prosecuting criminal cases. This led to the position of Municipal Judge. As a former prosecutor and judge, I gained mastery of every side of the courtroom - a quality that helps my clients succeed every day.
