Mr. Weiss is an experienced trial and appellate lawyer. As a partner in the firm's Litigation Practice Group, he has a particular focus in the areas of professional liability, lawyer discipline, and complex business litigation.

Mr. Weiss has successfully tried cases involving legal malpractice claims, commercial contract and real estate disputes, employee misconduct, and franchise/franchisor lawsuits. He also regularly represents clients in insurance litigation, religious institution litigation, director and officer liability litigation and a variety of other complex business matters.

Mr. Weiss has handled many appeals in state appellate courts and the Ninth Circuit Court of Appeals. He frequently is brought in to assist in appeals of cases that were litigated by other lawyers at the trial court level.

Mr. Weiss currently serves as a Judge Pro Tempore of the Arizona Superior Court in Maricopa County. Prior to joining the firm, he worked as a prosecutor and was first-chair lawyer in dozens of trials.

Pro Bono

Mr. Weiss regularly represents indigent clients on a pro bono basis. For example, Mr. Weiss recently completed a nearly decade-long representation of a man who was previously wrongfully convicted of first degree murder and sentenced to life in prison. After years of litigation in the state and federal courts, including multiple successful appeals and a five-week re-trial, a jury refused to convict Mr. Weiss' client on any charges. In recognition of his work on this case, the Arizona Public Defenders Association awarded Mr. Weiss and other members of the successful Lewis Roca Rothgerber Christie defense team the inaugural Robert J. Hooker Award, which recognizes exceptional contributions of private law firms to the criminal justice system.
