David A. Fusco

David Fusco is a litigation partner in our Pittsburgh office and a Practice Group Coordinator for our Mass Tort and Product Liability practice group. David maintains an active trial practice concentrating in the areas of class actions, complex commercial litigation, mass tort, and product liability, with an emphasis on defending manufacturers in claims related to alleged toxic substances. He serves as lead counsel in jurisdictions across the country and has experience defending claims involving asbestos, benzene, coal dust, dioxins and furans, ethylene oxide, PFAS, polycyclic aromatic hydrocarbons (PAHs), silica, and talc, among other substances.

David is an experienced litigator and focuses on developing innovative defense strategies in cases involving complex issues of liability and causation. His experience allows him to persuasively present sophisticated legal arguments and scientific issues in an intelligible manner, both when litigating a case to verdict and when leveraging defenses to obtain a favorable result prior to trial. David also has significant experience managing the defense of large dockets of repetitive tort claims filed across the country, with a focus on minimizing exposure, controlling costs, and maintaining predictability.

David has tried cases to verdict in Georgia, New York, Pennsylvania, and South Carolina and has served as trial counsel for cases in Alabama, Connecticut, Illinois, Louisiana, Missouri, and West Virginia. In developing and advancing his clients' defenses, David has conducted hundreds of expert depositions across various scientific disciplines, including disease causation, epidemiology, exposure assessment, industrial hygiene, pathological diagnosis, pulmonary function, and toxicology. He has also argued numerous Daubert and Frye motions regarding the admissibility of expert testimony in federal and state courts throughout the United States.

David served as Senior Assistant to the Chief of Staff in the Office of the Governor for the State of West Virginia from 2002 until 2004 where he worked with administration officials to develop various policy initiatives.

David spent his final semester of law school working as a judicial clerk for the Honorable Robert B. King, Circuit Judge for the United States Court of Appeals for the Fourth Circuit. He also worked as a judicial clerk for the Honorable Irene M. Keeley, Chief Judge for the United States District Court for the Northern District of West Virginia, during the summer of 2005.
