Catherine K. Dick

Catherine “Cassie” Dick is a former senior Department of Justice official whose practice focuses on high-stakes government enforcement actions, complex investigations, litigation, and trials spanning antitrust, health care fraud, consumer protection, and organized crime. Drawing on more than 15 years of experience and over a decade in leadership roles across five DOJ enforcement branches, she brings an insider’s understanding of how major government criminal and civil cases are built, how to navigate government enforcement actions, and how to try complex cases.

Before joining Sher Tremonte, Cassie served as Director of Litigation in the DOJ’s Antitrust Division, where she led all civil and criminal antitrust litigation nationwide. She oversaw strategy and trial preparation in some of the Division’s most significant matters, including monopolization and conduct cases involving Google, Apple, Live Nation, Visa, and Agri Stats, as well as merger challenges and other complex investigations. She developed and executed litigation strategies for all of these matters, including trials of Google and Live Nation, and the first criminal antitrust labor market trial resulting in a conviction.

Cassie’s experience extends well beyond antitrust. As Assistant Director and Trial Coordinator in the Civil Division’s Consumer Protection Branch, she supervised all criminal and civil trials, as well as numerous complex criminal and civil matters involving health and safety matters under the Food Drug and Cosmetic Act and Consumer Product Safety Act, consumer fraud, and data privacy.

Earlier in her career, Cassie served as an Assistant Chief in the Fraud Section, where she litigated and tried complex health care fraud cases, often with parallel False Claims Act matters. She was also an Assistant United States Attorney in the District of Maryland and a Trial Attorney in DOJ’s Organized Crime and Gang Section, where her matters included RICO and VICAR prosecutions, international cyber fraud, and money laundering.

Cassie began her legal career clerking for the Honorable Paul L. Friedman of the U.S. District Court for the District of Columbia and practicing at a large international law firm, where she handled complex commercial litigation and internal investigations. She has received numerous honors, including the Attorney General’s Award for Fraud Prevention, multiple Assistant Attorney General’s Awards, and recognition as a Service to America Medal finalist, along with commendations from federal enforcement agencies. She frequently speaks on government enforcement, white collar crime, and trial practice, and has trained prosecutors and law enforcement officials in the United States and abroad.
