Attorney Profile

Joseph P. St. Louis, who has been practicing law for over 28 years, is a Partner in the Law Firm of Nesci & St. Louis, P.L.L.C.. Mr. St. Louis has been recognized for his expertise in handling a variety of criminal defense cases, including major felony cases in both State and Federal courts, as well as DUI defense, DUI homicides, drug offenses, sexual offenses, violent crimes, and murder cases, including death penalty cases.

In 2014, Mr. St. Louis became one of fifteen members of the Board of Regents, charged with overseeing the National College for DUI Defense, the premier national DUI defense organization, with over 1,800 members.  Mr. St. Louis has been chosen as one of the best DUI lawyers in Tucson by Tucson Lifestyles magazine.  He has been chosen as one of the best attorneys in Arizona by Superlawyers magazine and AZ magazine in 2009-2017.  Mr. St. Louis is listed in the Best Lawyers in America, and has the highest rating possible given by Martindale-Hubbell, an AV-Preeminent rating.  Nesci & St. Louis has been recognized as one of the top law firms in the Country by U.S. News & World Report in 2011-2017. 

Mr. St. Louis received his Bachelor of Arts in Political Science from the University of Arizona in 1984, graduating with departmental honors. In 1987, he obtained his Juris Doctor degree from the University of Arizona College of Law. Mr. St. Louis is Certified by the Arizona State Bar as a Specialist in Criminal Law (June 2000 to the present). He is also Certified as a Specialist in DUI Defense by the National College for DUI Defense, recognized by the American Bar Association (July 2012 to the present).  Mr. St. Louis is the only lawyer in Arizona who has been awarded both of these certifications.  Only approximately five percent of attorneys currently practicing are certified as specialists in any area of the law.

Mr. St. Louis is a sought-after speaker on legal issues, and has spoken on a variety of legal topics at legal education seminars sponsored by a variety of State Bar and Defense Attorney organizations in Arizona, California, Colorado, Florida, Georgia, Illinois, Louisiana, Massachusetts, Mississippi, New Mexico, New York, Nevada, Ohio, Oklahoma, Tennessee, Texas and Wisconsin.   

Mr. St. Louis is a graduate of the National Highway Traffic Administration’s Student Course on Standardized Field Sobriety Testing, the National Highway Traffic Administration’s Instructor Course on Standardized Field Sobriety Testing, and the American Chemical Society’s Forensic Chromatography Course.

In 2003, at the request of the then-presiding chief judge of the Pima County Justice Courts, Mr. St. Louis served as a part-time Justice of the Peace. In 2006, he also served as the president of Arizona Attorneys for Criminal Justice – Arizona’s leading defense attorney organization, with over 400 members.

Mr. St. Louis has handled death penalty cases, both in state court where he was lead counsel in Pima County’s first death penalty case tried completely to a jury (the client received a prison sentence after Mr. St. Louis convinced the jury not to impose the death penalty), and in federal court where he was found to be qualified as "Learned Counsel," a designation reserved for only the most qualified attorneys handling these cases. Mr. St. Louis has the unique distinction of having had two back-to-back first-degree murder cases in which the judges dismissed all murder charges during trial.

Mr. St. Louis has tried over 150 cases to juries, on both misdemeanor and felony charges, in Federal court and in State courts throughout Arizona. He has also argued cases before the Arizona Court of Appeals, the Arizona Supreme Court, and the Ninth Circuit Court of Appeals.

In 2013, Mr. St. Louis was one of four attorneys who conducted a 17 day court challenge to the manner in which blood was being tested in the Scottsdale Crime Laboratory, in the Maricopa County Superior Court, which resulted in the trial court suppressing all blood alcohol evidence in 11 felony cases.  

Mr. St. Louis recieved the Boy Scouts of America's District Award of Merit in 2010, and serves as the attorney coach for the Basis Oro Valley Mock Trial team.
