Benjamin Gruenstein has founded Gruenstein Law PLLC, a law firm dedicated to providing elite-level representation and advocacy for companies, their boards of directors and senior executives. The new firm will focus on government and internal investigations, white-collar criminal cases, regulatory enforcement and complex civil litigation.
“The practice of law is undergoing monumental changes,” said Gruenstein. “I look forward to building a law firm from the ground up that delivers premier legal services using small teams of exceptional lawyers, augmented by the transformative legal technology now available. This is an exciting time for lawyers and clients who are looking for cutting-edge, strategic and efficient representation.”
Gruenstein is widely recognized as one of the nation's leading corporate investigations and white-collar defense lawyers. Before founding Gruenstein Law, Gruenstein served for 14 years as a partner at Cravath, Swaine & Moore LLP, where he was a founding member of the firm's Investigations and Regulatory Enforcement Practice. In that role, he was a strategic advisor to companies and executives in government and internal corporate investigations and accompanying civil litigation across a broad range of matters—including securities and accounting fraud, money laundering, healthcare fraud, trade sanctions, theft of trade secrets, the Foreign Corrupt Practices Act and the False Claims Act.
Before joining Cravath, Gruenstein served as a federal prosecutor in the U.S. Attorney’s Office for the Southern District of New York. He is a magna cum laude graduate of Harvard Law School, where he was an editor of the Harvard Law Review. After law school, Gruenstein clerked on the U.S. Court of Appeals for the District of Columbia Circuit for Judge Stephen F. Williams and on the U.S. Supreme Court for Justice David H. Souter
