Pete Mazza is a trial lawyer who focuses on matters investigated by government agencies, including the DOJ and SEC, internal investigations, complex civil litigation, and compliance issues. He has been counsel in federal court in more than a dozen jury trials and has argued before the Ninth Circuit Court of Appeals on numerous occasions.

Prior to joining Jones Day in 2014, Pete served as an Assistant U.S. Attorney in the Southern District of California for eight years, where he led dozens of complex grand jury and wiretap investigations into matters involving the Foreign Corrupt Practices Act, tax evasion, public corruption, racketeering, money laundering, schemes to defraud, aggravated identity theft, and drug trafficking. Two such investigations resulted in the prosecution of more than 30 individuals related to multimillion dollar tax and bank fraud schemes and the prosecution of a former public official for extracting an illegal political contribution from a prospective contractor. Pete's felony jury trials included the conviction of a tax lawyer/CPA for the evasion of more than $1.5 million in taxes and a post-extradition, drug-trafficking case against an international crime leader that resulted in a life sentence. From 2010 to 2014, Pete also served as the DOJ's Stolen Identity Refund Fraud Coordinator for the Southern District of California.

Pete is the 2016 president of San Diego Chapter of the Federal Bar Association. He also has served as an adjunct professor at California Western School of Law where he has taught classes on transnational criminal issues.
