Quinn emanuel trial lawyers

Gerger, David

David Gerger



David is Managing Partner of the Houston office and chair of the Houston White Collar and Corporate Investigations Group.

Over 25 years, David has handled hundreds of investigations, trials, and appeals for individuals and businesses, foreign and domestic, public and private. The biggest victory can be quietly stopping a case, and David has helped clients avoid charges in many DOJ, SEC, and other government investigations. But David is equally known for his courtroom victories in cases involving: antitrust, environmental, securities, immigration, commodities, banking, domestic or foreign bribery, elections, government contracting, and other areas.  David also is recruited to try civil cases, often to join or substitute for counsel before trial.

David is a Fellow of the American College of Trial Lawyers and the American Board of Criminal Lawyers and a former Federal Public Defender who has long been listed in “Best Lawyers in America” and “SuperLawyers.” After graduating Yale College and University of Texas Law School, he clerked for two federal judges and practiced for 25 years before starting the Houston office of Quinn Emanuel Urquhart & Sullivan. Best Lawyers, Texas Edition, named David "Best White Collar in Houston" for 2015-2016.
