R. Tyler Bezilla's interest in law began at the Pennsylvania State University where he participated in the Mock Trial program. After graduation he attended the Antonin Scalia Law School and was a member of the Trial Advocacy Board and Moot Court Board. In both programs he was a lead member of competitive teams that competed nationally. In Trial Advocacy, his team was the national runner up in the American Association of Justice competition, defeating over 200 other law schools. In Moot Court, he advanced to the national rounds of the New York Bar Association Moot Court Competition.

While taking classes and competing, Tyler interned at the Loudoun County Public Defender's Office, a local immigration law firm, and finally with the Fairfax Commonwealth Attorney's Office. Upon graduation he became an Assistant Commonwealth's Attorney in Fauquier County, where he prosecuted DUI, traffic cases, juvenile crimes, drug cases, felony offenses, and traffic-related fatality cases. He also tried many of these cases before juries in Circuit Court. During his time in Fauquier he trained law enforcement on DUI law, gave appellate updates on legal changes, and volunteered for student government day. He was also an active member of the Fauquier County Bar Association.

Tyler left Fauquier County to become an Assistant Commonwealth's Attorney in Fairfax County. He was promoted to Senior Assistant and placed in charge of the Circuit Court, or major crimes, division of the office. There he was responsible for managing felony prosecutors, working with police during their investigations, and trying major violent crimes in Circuit Court. Among those cases, Tyler secured convictions on a number of murder and death-related cases. Some of these matters appeared on 48 Hours and other national news organizations. In addition to his Circuit Court responsibilities, he served as the point of contact for the Crash Reconstruction Team in Fairfax County. His duties included approving charges, assisting investigations, and prosecuting fatalities resulting from traffic crashes.

Having concluded his service to the community, Tyler then left the Fairfax Commonwealth's Office to pursue a career in private practice. He now defends clients charged with crimes in the Northern Virginia area. His practice areas include murder, robbery, arson, rape, and other major felony offenses. He also represents clients in DUI and traffic matters.
