(Law360 also recognized Mr. Neuwirth as one of eight competition law “MVPs” nationwide in 2012.) Mr. Neuwirth handles a broad range of litigation matters, with particular emphasis on antitrust, contract disputes, corporate governance, class actions, and matters arising from transactions between foreign and U.S. businesses. Mr. Neuwirth brings to bear over two decades of experience in private practice and government, including serving as Associate White House Counsel to President Clinton from 1993-1996. In 1998, the U.S. Department of Justice retained Mr. Neuwirth to assist in the Antitrust Division’s litigation against Microsoft Corporation. Mr. Neuwirth is the rare lawyer with a “blue chip” practice on both sides of the “v,” representing major corporations as plaintiffs and defendants in individual and class actions. Chambers USA (2008) described Mr. Neuwirth as “renowned for his deep understanding of corporate transactions and antitrust matters.” Mr. Neuwirth appears in the 2013 edition of The Best Lawyers in America.
