Former federal prosecutor joins Roanoke firm.

Woods Rogers PLC in Roanoke has named Thomas Cullen, previously an assistant U.S. attorney in the Western District of Virginia, as a new principal at the law firm.

The former federal prosecutor in Virginia and North Carolina will represent organizations and individuals in a wide variety of investigations and enforcement proceedings conducted by federal and state agencies. Most recently, Cullen was the deputy criminal chief in the U.S. Attorney’s Office for the Western District of Virginia, where he oversaw numerous white-collar, narcotics, and RICO prosecutions.

“I look forward to joining Woods Rogers to provide clients with a prosecutor’s perspective,” Cullen said in a statement.

Cullen has substantial litigation experience. As an assistant U.S. attorney, he has directed dozens of grand-jury investigations with numerous federal law enforcement agencies, including the Federal Bureau of Investigation, the Internal Revenue Service, the Department of Homeland Security, the U.S. Secret Service, the Bureau of Alcohol, Tobacco, Firearms, and Explosives, and the Drug Enforcement Administration.

Before joining the U.S. Attorney’s Office, Cullen worked as a law clerk to Judge Roger L. Gregory on the U.S. Court of Appeals for the Fourth Circuit and Judge Robert E. Payne on the U.S. District Court for the Eastern District of Virginia.
