Deputy Chief of US Attorney's Organized Crime Unit Heads to Private Practice

Sidley Austin LLP announced today that Timothy Treanor has joined the firm as a partner, resident in New York. Treanor, who most recently served as the Deputy Chief of the Organized Crime Unit in the United States Attorney's Office for the Southern District of New York, will focus his practice on white collar defense and investigations.

Treanor is an experienced prosecutor and investigator of securities, healthcare and bank fraud, wire and mail fraud, racketeering, money laundering, tax evasion and other business crimes. He has conducted a dozen significant federal criminal trials, convicting all 24 defendants. Treanor joined the U.S. Attorney's office in 1999 and held several leadership positions before his appointment, by U.S. Attorney for the SDNY, Michael Garcia, to be Deputy Chief of the Organized Crime Unit in 2006.

“Tim is a highly respected trial lawyer who led the government’s efforts on a number of important white collar and criminal investigations and trials in recent years,” said Steven Bierman, a member of the firm’s Executive Committee and a global coordinator of the firm’s complex commercial litigation practice. “We look forward to working with him on the further expansion of our white collar practice in New York.”

“I am pleased to be joining a firm I have long respected,” said Treanor. “Sidley already has strength and a great reputation in white collar, securities and complex commercial litigation, and I am looking forward to expanding the depth of services we can offer to the firm’s impressive roster of clients.”

Treanor received his J.D. degree from Fordham Law School, where he was Notes and Articles Editor of the Law Review and graduated Order of the Coif. He received his B.A. degree from the College of the Holy Cross. Treanor clerked for U.S. District Judge Harold Allbritton III of the Middle District of Alabama.
