Eddie R. Mendoza

Eddie Mendoza draws on his experience as a former federal prosecutor and DOJ trial attorney to guide clients through complex investigations involving white-collar criminal offenses and criminal and civil tax controversies. He represents individuals and businesses facing federal enforcement actions, including those brought by the Department of Justice and the Internal Revenue Service, and conducts internal investigations aimed at identifying and resolving issues before they escalate.

Before joining the firm, Mr. Mendoza served as an Assistant U.S. Attorney, where he prosecuted hundreds of federal criminal cases, and later as a Trial Attorney in the DOJ’s Tax Division, where he litigated high-dollar tax disputes. His experience handling criminal and tax matters at the DOJ gives him unique insight into government investigations and complex litigation, allowing him to navigate enforcement actions with precision and efficiency.

At the DOJ, Mr. Mendoza led grand jury investigations, prosecuted a wide range of federal crimes, litigated dispositive motions, and handled sentencing and probation-revocation proceedings. He tried six felony cases to jury verdict, securing convictions in five—including one affirmed by the en banc U.S. Court of Appeals for the Fifth Circuit. On the civil side, he litigated multimillion-dollar tax disputes, including refund suits, fraudulent transfer actions, and enforcement cases against tax return preparers. He also handled nominee and alter ego liability cases, IRS summons enforcement actions, and constitutional challenges to the Internal Revenue Code based on the First Amendment’s Free Speech and Free Exercise Clauses. In 2024, the DOJ recognized his work on a complex civil tax fraud case in Dallas with a Special Commendation. Earlier in his career, Mr. Mendoza practiced in the Dallas office of an international law firm, where he represented large companies in criminal and civil litigation, including a corporation under federal criminal probation and corporate monitorship.

Mr. Mendoza began his legal career clerking for U.S. Magistrate Judge Renee H. Toliver and U.S. District Judge Marina Garcia Marmolejo. He is an honors graduate of St. Mary’s University School of Law, where he served as an editor of the St. Mary’s Law Journal.
