George Varghese joined WilmerHale as a partner in the firm’s Boston office, following more than a decade of work as a federal prosecutor in Washington and Massachusetts.

Varghese, who managed investigations and litigation of complex criminal cases involving health care fraud, money laundering, racketeering, cybersecurity, economic sanctions, will work out of the firm’s white collar defense and investigations group.

While an assistant U.S. attorney in Boston, he led the prosecution of New England Compounding Center. That was the pharmacy responsible for a nationwide deadly fungal meningitis outbreak in 2012.

“It took up the last seven years of my career,” Varghese said. “When I finished with that, I felt like it was time to work on something new.”

In 2019, Varghese prosecuted a defendant who participated in the Rwandan genocide.

“When I got done with that, nothing on my plate was as interesting or challenging as NECC or the Rwandan trial,” he said. “I wanted to keep challenging myself and growing my legal skills.”

He chose WilmerHale in large part because of the firm’s deep bench of former prosecutors and government attorneys.

“They get complicated cases,” Varghese said. “They get hard legal issues and they’re not handling run of the mill contract disputes.”

Susan Murley, co-managing partner of WilmerHale, said in a statement that “George is a top-notch litigator who is well-respected for his ability to lead complex criminal matters from investigation to trial.”
