Former chief of SDNY Criminal Division joins Mayer Brown

Daniel Stein, former Chief of the Criminal Division in the U.S. Attorney’s Office for the Southern District of New York (SDNY), will join the law firm Mayer Brown as a partner in the Litigation & Dispute Resolution practice, where he will lead the firm’s global regulatory and investigations group and serve as a co-leader of the white-collar defense and compliance group.

Stein’s decade-long career with the U.S. Attorney’s Office in New York included two terms of duty. He first joined in 2003, where, as an assistant U.S. attorney, he investigated and prosecuted cases involving a wide range of federal crimes, including those involving companies in the financial services industry. In this role, he represented the United States in several significant criminal public corruption cases. From 2009 to 2011, he served as Chief of the Office’s Public Corruption Unit, where he was the principal trial counsel in more than a dozen criminal trials and argued numerous appeals in the U.S. Court of Appeals for the Second Circuit.

In 2014, at the request of Preet Bharara, Stein rejoined the U.S. Attorney’s office, serving as chief counsel to the U.S. Attorney before stepping into his most recent role for the past year, where he oversaw the SDNY’s criminal prosecutions and investigations, including those involving securities fraud, insider trading, public corruption, foreign corrupt practices, criminal tax offenses, money laundering, economic sanctions, cybercrime, narcotics trafficking, violent crimes and terrorism.

Between stints in the SDNY, Stein spent several years in private practice, where he handled criminal and regulatory matters for a number of major financial institutions and other clients.

At Mayer Brown, Stein will focus his practice on representing and counseling financial services firms on regulatory enforcement, including securities enforcement, government and internal investigations, white-collar criminal defense and complex civil litigation. He will counsel corporate and individual clients in a range of complex issues, including the Securities Exchange Commission and Financial Industry Regulatory Authority investigations and enforcement actions.
