Warren Postman is a Partner at Keller Lenkner LLC. He combines a deep understanding of the civil litigation system with broad substantive expertise to solve complex litigation challenges for the firm’s clients.
Warren has helped build Keller Lenkner’s arbitration practice, which devotes unparalleled resources to resolving the claims of consumers and employees who are subject to forced arbitration clauses. The firm’s commitment to arbitration allows it to aggressively pursue individual arbitrations for tens of thousands of clients simultaneously and, as described by the New York Times, has left defendants “scared to death.” Warren has won numerous precedent-setting victories requiring defendants to comply with their obligation to arbitrate under agreements they drafted. And in the last two years alone, Keller Lenkner has pursued individual arbitrations and obtained favorable resolutions for more than 100,000 individual clients.
Before joining Keller Lenkner, Warren was Vice President and Chief Counsel for Appellate Litigation at the U.S. Chamber Litigation Center. In that role, he managed appellate strategy for the U.S. Chamber of Commerce, which participates in more than 150 cases each year to shape the law on a wide range of issues affecting businesses. Working closely with senior in-house lawyers at some of the world’s largest companies, Warren gained unique insight into the dynamics and trends that shape business litigation. Warren was previously an attorney in the Issues & Appeals practice at Jones Day, where he helped guide trial and appellate strategy in some of the firm’s most complex and high-stakes cases.
Warren served as a law clerk for Justice David H. Souter at the Supreme Court of the United States and Judge William A. Fletcher at the U.S. Court of Appeals for the Ninth Circuit.
