LOS ANGELES , Sept. 2, 2026 /PRNewswire/ -- David M. Herzog , a former Assistant U.S. Attorney in California and Washington, joined global law firm Greenberg Traurig, LLP as a Litigation Practice shareholder in the firm's Los Angeles office . Herzog will focus his practice on complex commercial litigation , products liability and mass torts , class action defense , appeals , and trial work. He also will advise clients on government-related investigations , compliance, and government enforcement matters, drawing on his deep experience navigating federal prosecutorial priorities and overseeing litigation strategy. "Dave is a seasoned trial and appellate lawyer whose career reflects a rare combination of leadership, courtroom experience, and strategic judgment," Greenberg Traurig Chief Executive Officer Brian L. Duffy said. "As companies continue to face increasingly sophisticated disputes and regulatory challenges, Dave's ability to manage sophisticated matters from investigation through trial and appeal will be an enormous asset to our clients and our firm." Herzog previously served for more than 18 years with the U.S. Attorney's Offices in Los Angeles and Spokane, Washington, where he held numerous leadership roles, including Chief of Appeals, Deputy Criminal Chief, and Deputy Chief of the Violent and Organized Crimes Section. Throughout his public service career, he oversaw complex investigations, tried numerous federal cases, and briefed and argued dozens of matters before the U.S. Court of Appeals for the Ninth Circuit.

Newman in private practice, and with Thomas P. O'Brien and Ivy A. Wang at the U.S. Attorney's Office in Los Angeles.
