Shaun is a fearless trial lawyer who takes on, tries, and wins tough cases, whether civil or criminal—seeing a path to victory that others often miss. He considers trial strategy from the first meeting with a client, thinking about every detail of trial presentation while never losing sight of the big picture. He helps clients avoid or minimize litigation risks, too, by skillfully navigating complex criminal and corporate investigations. He is deeply familiar with their contours, having worked as a prosecutor leading multi-agency investigations and prosecutions.

In private practice, Shaun has led defense teams in nearly every area of white-collar criminal defense. He has helped clients avoid indictment or secured early dismissal of charges. And in cases that proceed to trial, he has repeatedly won acquittals. Many of his victories have come in high-profile cases such as the acquittal of a BP employee charged with causing the Deepwater Horizon tragedy, dismissal of charges against a Division I college coach in the “Varsity Blues” college admissions scandal, and the Fifth Circuit Court of Appeals decision immunizing offshore contractors from criminal charges under the Outer Continental Shelf Lands Act.

Shaun has also successfully handled high-stakes civil cases, such as multi-district opioid, healthcare, environmental, False Claims Act, and other “bet the company” litigation. He likewise has experience in arbitrations and appeals.  His clients range from Fortune 50 companies to individuals.
