For two decades, Mr. Pennock has been chair of one Weitz & Luxenberg’s national litigation practice groups.

He is directly responsible for leading a large national litigation department covering all aspects of litigation — from inception through trial. He has served as lead plaintiffs’ counsel, as well as plaintiff steering committee member, and liaison counsel in numerous state and federal multidistrict-litigation (MDL) mass tort cases.

Proudly, in 2015, he was named national co-lead counsel of the federal power morcellator MDL, where he organized the first majority women Plaintiff Steering Committee in the 47 year history of multidistrict litigation. 

He currently serves as Chair of the Plaintiffs’ Executive Committee in the PPI MDL and, in addition, he is leading efforts to hold accountable those businesses that have for years profited from sex trafficking. Mr. Pennock has also worked to expose the purveyors of opioids, including conducting depositions of key corporate executives at the nation’s 4th largest drug distributor. As co-lead of the federal court Actos Multidistrict-Litigation coordination from 2012 through 2018, he helped lead the litigation efforts that resulted in a $9 billion jury verdict, at the time the highest jury verdict in history for a personal injury case. 

Mr. Pennock has also handled numerous bellwether trials and Daubert hearings on expert-witness testimony in both state and federal courts, but has also handled a wide range of difficult matters. From pro bono representation of a woman/stepmom cut-out of her deceased significant other’s estate to resolving the claims of several people alleging discrimination because they are transgender, Mr. Pennock has always taken on matters to fight for what is right.

As a well-respected member of the bar, he has been an invited speaker to dozens of legal conferences around the country, as well as at several law schools including Yale, Brooklyn, and the University of Denver, among others.

In 2007, he was honored with the invitation to author the mass tort litigation chapter in a two-volume legal treatise, “The Plaintiff’s Personal Injury Action in New York State” published by New York State Bar Association, edited by Patrick J. Higgins. It was published in 2009 and Mr. Pennock regularly provides updates. 

Every year since 2007 he has been designated a ”Super Lawyer.” He also has been a long-running ”Best Lawyers” honoree. The National Law Journal calls him one of  ”America’s Elite Trial Lawyers.” Recently, he was accorded the coveted Clarence Darrow Award, which recognizes dedication and excellence in the legal profession and is given to attorneys who have demonstrated exceptional conviction in their work.

Mr. Pennock is widely considered, by both sides of the bar, as one of the best and most aggressive plaintiff litigators in the country. His work has led to more than a billion dollars in recoveries for Weitz & Luxenberg clients.
