Peter T. Grossi, Jr.

Senior Counsel

According to Chambers USA, Peter Grossi is the "Senior Statesman" of the national products liability bar, having been "singled out by his clients for his knowledge of all things pharmaceutical." Chambers reports that he "receives bountiful praise when it comes to the medical aspects of pharmaceutical litigation and obtains amazing results at trial" and is "a strategic mastermind when looking at mass torts as a whole."

From 1997 to 2007, Mr. Grossi served as National Counsel for Wyeth in its Diet Drug litigations. After obtaining the first defense verdict in a Diet Drug jury trial, he thereafter tried 12 more cases to successful conclusions, and was the senior supervising attorney of teams in 40 other trials. According to the 2013 LMG Guide, he "garnered a reputation as one of the best product liability lawyers in the industry's history." Before and since his Diet Drug work, he has defended a number of other pharmaceutical companies, as well as those in other industries, in product liability cases. He has also had significant trial experience in other practice areas focusing on scientific issues such as antitrust, false advertising, and patents.

Mr. Grossi is currently on the law school faculties of Harvard, University of Pennsylvania, University of Virginia, Columbia, and Yale University where he teaches product liability courses. He has also spoken on various trial practice and product liability issues to national meetings of the Defense Research Institute, the AEI-Brookings Judicial Education Program, and various sections of the ABA.

Mr. Grossi served as a member of the ABA Task Force on Preservation of the Justice System and was the co-author of their report, Crisis in the Courts (2011). He was also a Special Advisor to the ABA's Standing Committee on Judicial Independence.

Mr. Grossi maintains an active pro bono practice with the Washington Lawyers' Committee for Civil Rights and Urban Affairs. In 2016 he received the Committee's Outstanding Achievement Award for Disability Law. In 2017, Mr. Grossi received the Daniel Gribbon Award at the DC Circuit Judicial Conference for the outstanding pro bono representation in the US District Court for the District of Columbia for a lawsuit in which he obtained one of the largest jury awards for pregnancy-based discrimination. In 2018, he was one of four finalists for the "Trial Lawyer of the Year" awarded by Public Interest for his work representing plaintiffs seeking health benefits for same sex spouses in Cote v. Walmart.
