William A. Isaacson⏐Partner

Bill Isaacson is widely considered one of the preeminent trial lawyers of his generation. A Fellow of the American College of Trial Lawyers, Bill was named a “Litigator of the Year” in 2016 and a “Litigator of the Week” three times by The American Lawyer. Chambers and Partners reports that Bill is a “celebrated trial lawyer” and is “highly recommended for his work in complex class actions,” with clients commending his “superb intellect” and that he is a “very smart strategist.” 

Law360 has described Bill as a trial lawyer who “simplifies difficult facts and technologies and makes them understandable to a jury,” and has said that his noteworthy cross-examinations have "changed the court's thinking overnight.” His effectiveness in the courtroom has also caught the attention of the Wall Street Journal, which observed that, following a cross-examination from Bill, "there was a distinct feeling in the air that change was coming."

Bill has tried cases in a number of areas, including contract, commercial torts, copyright, international arbitration, and antitrust. In antitrust, Bill has successfully represented both plaintiffs and defendants in major antitrust litigations and has tried more federal antitrust class actions in this century than any other lawyer, all of which were major victories.

Global Competition Review has noted that “arguably no antitrust lawyer in recent memory has had as much success for both plaintiffs and defendants as Bill Isaacson.” Lawdragon writes that it is “nearly impossible to find a more reliable antitrust litigator than Isaacson, who has successfully handled several of the most high-profile cases in the past two decades.”

Bill has achieved numerous industry awards over the years. Bill is among only 31 lawyers to be named in the Lawdragon 500 each of the last 10 years; Law360 has twice named Bill a “Competition MVP” and also has named him a “Titan of the Plaintiffs Bar.” Global Competition Review has named him a “Litigator of the Week.” He is also recognized by The Legal 500 as a “Hall of Fame Lawyer” in the Antitrust: Civil Litigation/Class Actions: Plaintiff category, a “Leading Lawyer” in the Trial Lawyers category, and is recommended in the Antitrust: Civil Litigation/Class Actions: Defense category. 

Bill is also a sought-after speaker at the nation’s top legal conferences, including NYU Law School’s conference on Antitrust and 21st Century Bigness; the American Antitrust Institute; the Sedona Conference; and MLEX Advisory Board; and has conducted mock trials for the Spring and Fall ABA Antitrust Conferences and the ABA Economics Institute for Judges at George Mason University. 

Bill is a member and former Chair of the Board for Legal Counsel for the Elderly. In 2015, the group recognized him with its individual Award for Sustained Excellence and Outstanding Commitment. He is also the trustee of the Garry Shandling Charitable Trust (www.garryshandling.com). His pro bono work has been featured in articles in the Washington Post.
