Ira M. Feinberg

Ira Feinberg takes on clients' most challenging legal problems and presents their arguments in the most persuasive way. Ira has been recognized for his notable legal abilities, whether as an editor of the Harvard Law Review, clerking for Thurgood Marshall on the Supreme Court, or as Mary Jo White's Chief Appellate Attorney at the U.S. Attorney's Office. He cuts through complex problems quickly and provides clients with answers that are pragmatic, well-reasoned, and clear.

Ira's practice focuses on two areas the defense of white collar prosecutions and investigations, and civil or criminal appellate matters. He handles the defense of investigations by the U.S. Attorney's Offices, Department of Justice, the U.S. Securities and Exchange Commission (SEC), and the NY Attorney General's Office, representing both companies and individuals. On the appellate side, Ira is frequently retained to brief and argue appeals that others have handled in trial. Ira also has vast experience handling civil and commercial litigation, and has also handled major pro bono litigation for the Brennan Center and the Lawyers' Committee for Civil Rights.

Previously, Ira was an Assistant U.S. Attorney (AUSA) in the Southern District of New York for 11 years. As an AUSA, he was responsible for leading federal investigations and prosecutions, and successfully tried approximately 10 jury trials. Ira was then promoted to Deputy Chief and then Chief Appellate Attorney, where he supervised all of the office's criminal appeals in the Second Circuit and was a trusted advisor to the U.S. Attorney. He has argued more than 35 cases in the Second Circuit, New York Court of Appeals, and other appellate courts.

Before joining the U.S. Attorney's Office, Ira clerked for Chief Judge Henry Friendly of the Second Circuit and Justice Marshall. He has also taught courses in federal criminal law at Harvard Law School.
