STEPHEN PAUL BARNARD, J.D. is a graduate of the University of Arizona Law School. As a defense attorney he limits his practice to defending those involved in vehicular crimes with an emphasis on DUI's.

In his 30 years of experience he has represented clients in over 800 Jury Trials involving driving under the Influence of alcohol or drugs. These trials included charges such as DUI, Aggravated DUI, Aggravated Assault by Vehicle, Endangerment by Vehicle, Manslaughter, and Second Degree Murder by Vehicle.

Being charged with a DUI is taken very seriously by the prosecution in the State of Arizona. There is often no significant plea-bargaining or reduction of charges and sentencing. As such, it is Mr. Barnard's firm belief that the only proven way to obtain the best results for his client is to take their cases to trial and win. This is what he does best.

If a case does go to trial, Mr. Barnard's experience as an ex-prosecutor has provided him with the knowledge of how both sides will approach the case. He not only knows the best trial defense strategies, but is also familiar with how the prosecution will attempt to prove their case.

A successful defense requires the service of a skilled trial lawyer, associates, and a staff that has immediate access to the most up to date research materials and trial techniques. In accordance with these guidelines, this office thoroughly investigates the allegations made against our clients. We interview all significant witnesses in a case and make sure that their testimony is preserved. We obtain and review all written materials and prepare photographs, diagrams, charts, and other illustrations for trials. We submit motions directed at the exclusion of prejudicial or wrongfully obtained evidence in every case. And we employ investigators, accident re-constructionists, forensic experts, and jury selection experts as necessary for every client.

Mr. Barnard's expertise does not end at the trial level. He and his capable staff have been responsible for more than twenty precedent setting cases before the Court of Appeals and the Supreme Court of Arizona. Our involvement in these cases have furthered your right to change judges in lower courts, your right to counsel during a DUI investigation, and your right to obtain independent evidence.

Mr. Barnard is an A rated lawyer by Martindale Hubble, a branch of the renowned legal publishing company Lexis Nexus. He is also a member of the National Association of Criminal Defense Lawyers, the America Trial Lawyers Association, the American Bar Association, the National College for DUI Defense, and is on the board of governors for Arizona Attorneys for Criminal Justice where he heads the DUI committee.

He has participated in a variety of legal seminars as a featured speaker for the State Bar of Arizona, Pima County Bar Association, Maricopa County Bar Association, Maricopa Public Defenders Office, Arizona State University, as well as the 2nd and 3rd DUI Judicial Conferences.

On top of this he is the Co-founder and Monitor of the AACJ Aggressive Defense of the Accused Impaired Driver seminar, an annual teaching seminar for lawyers where nationally renowned DUI attorneys and experts gather to share their expertise. Mr. Barnard has hosted and helped run this seminar in Tucson, Arizona for 27 years.

He is admitted to practice in all courts in the state of Arizona, the Federal District Courts the Ninth Circuit, and the Supreme Court of the United States.
