  • Credentials

Sean McNally is a litigator specializing in Criminal and DUI offenses. Sean is a graduate of the University of Arizona, James E. Rogers College of Law. While in law school, Sean focused primarily on criminal defense law, earning a Certificate of Criminal Law and Policy, and working primarily with the Pima County Public Defender’s office. Upon graduation, Sean was presented with the Hon. Joseph M. Livermore Service Award. After law school, Sean clerked at the Arizona Court of Appeals for the Hon. Sean E. Brearcliffe, prior to joining Nesci & St. Louis.

Prior to his career in law, Sean served with distinction in the United States Air Force for 20+ years, predominantly as a Tactical Aircraft Maintenance Superintendent. He is an adopted son of Arizona, having moved to Tucson in the eighth grade. He is a graduate of Cholla High School and of Arizona State University, where he received his Bachelor of Applied Science in Political Science.

Since joining Nesci & St. Louis, Sean has focused on pretrial litigation and trial work in DUIs, misdemeanors, and felonies in courts throughout Arizona. Sean’s recent wins include having a client facing mandatory prison time acquitted of all felony charges at trial. Sean has also convinced a judge to throw out his client’s prior convictions, changing a felony case in which his client faced mandatory prison time to a first-time misdemeanor DUI. Sean also had all of his client’s charges dismissed by the court, after getting a law enforcement officer to admit under oath that he had falsified records, eventually resulting in the officer being fired.

When Sean is not defending individuals accused of crimes, he spends his time watching his daughter play softball, and enjoying evenings with friends and family.

"I would highly recommend Nesci & St. Louis to anyone that needs them, especially Sean McNally one of the Lawyers there. He is very professional and explained everything in detail, and he and his staff kept me informed about the procedures every step of the way." - Former Client
