Ryan Huffman vigorously represents accused individuals throughout all stages of litigation, including trials and appeals. His experience includes both misdemeanor and felony criminal matters. He focuses on a pretrial motion practice, seeking to have his clients’ cases dismissed prior to trial, and is passionate about advocating against unethical police tactics and procedures. Not afraid to take a case to trial, after demonstrating issues with the way in which the case was charged, Ryan recently negotiated a plea to probation in the middle of a trial in which his client was facing life in prison. Other recent trial wins for Ryan include an acquittal for a client with an alleged blood alcohol concentration of .131, and successfully demonstrated to a jury trial that a reported breath test result of .250 was unreliable, resulting in a complete acquittal of all BAC charges for his client.

Sean McNally is a litigator specializing in Criminal and DUI offenses. 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. 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.
