Stephen Weissman recently rejoined the firm after serving as the Deputy Director of the Federal Trade Commission's Bureau of Competition from 2013-2015. At the FTC he was involved in and supervised the agency's review of hundreds of merger and non-merger investigations and enforcement actions, covering a wide range of industries including pharmaceuticals and other healthcare sectors, consumer products, energy, high-tech and chemicals. He was lead trial counsel for the FTC in its challenge of a $3.5 billion merger between food service distributors Sysco Corp. and U.S. Foods Inc., a case considered by many as the agency's most important merger litigation in more than a decade. He was recognized in 2016 by Global Competition Review as finalist for both its "Lawyer of the Year" and "Litigator of the Year" awards.
