John defends companies in a broad range of litigation, including product liability, toxic tort, complex commercial and financial services litigation, as well as in appellate matters. He has represented manufacturers of a wide variety of products, including cigarettes, prescription pharmaceuticals, specialty chemicals, industrial equipment and asbestos.

John has substantial experience in all phases of litigation:

Pre-trial Discovery – John has deposed plaintiffs, experts and other significant fact witnesses, and he has prepared company witnesses and experts for deposition. John has also drafted and responded to written discovery requests and litigated discovery disputes.

Expert Witness Development – John has identified and developed expert witnesses in a variety of areas, including medicine, toxicology, chemistry and workplace safety.

Trial – John handles complex legal issues and appellate preservation at the trial court level, and he has served on more than a dozen trial teams defending a major consumer products manufacturer in product liability cases. He was the primary legal issues attorney at three recent trials in which he was responsible for briefing and arguing Daubert, dispositive, trial procedures and in limine motions; identifying and arguing evidentiary and legal issues; all aspects of appellate preservation; coordinating preparation of bench memoranda and motions submitted during trial; arguing jury instruction and verdict form issues during charge conferences; and briefing and arguing directed verdict motions.

Post-Trial and Appeal – John has drafted post-trial motions that have resulted in the trial court ordering a new trial and, in another case, an appellate court reversing and remanding the case for a new trial. He has also co-authored various appellate briefs, including petitions for allowance of appeal to the Pennsylvania Supreme Court and amicus briefs.

John has also maintained an active pro bono practice, including representing individuals appealing the denial of asylum claims in the U.S. Court of Appeals for the Second Circuit in cases in which the Department of Justice sought remand to the Board of Immigration Appeals. John participated in New York City's Corporation Counsel's Public Service Program and served as counsel for the City of New York and several other defendants in a personal injury action, which was resolved on favorable terms the evening before jury selection. John has also reviewed case files for the Midwest Innocence Project to determine whether the factual record supports claims of actual innocence.

Prior to joining Shook, John was an associate in the New York, Jersey City and Miami offices of Hughes Hubbard & Reed LLP. He began his legal career as a summer associate and associate at Duane Morris LLP in Philadelphia.
