About me

Kyle Therrian attended law school at the University of Oklahoma where he was recognized as one of the top advocates in his class and inducted into the Order of Solicitors. While attending law school, he focused his legal education on the practice of Criminal and Constitutional Law.

Unsatisfied with learning law strictly in a classroom setting, Kyle dedicated much of his time outside of class to learning the art of litigation and criminal trials. Kyle was the named the Captain of the OU's prestigious White Collar Crime Mock Trial Team, and was invited to compete in the Black Law Student Association's regional mock trial competition where he received the honor of "Best Advocate." Between the classroom and the courtroom, Kyle also served his classmates as President of his school's chapter of the Phi Alpha Delta Legal Fraternity.

After moving back to Texas, Kyle began practicing law as a volunteer attorney at the Collin County District Attorney's Office. At that office, Kyle was involved in all aspects of criminal prosecution including numerous misdemeanor trials. That experience was the foundation upon which he started his criminal law practice at Rosenthal & Wadas, PLLC.
