Marc Penchansky has a varied practice with a focus on insurance coverage and related litigation, class actions, insurance broker and agent liability, medical malpractice, and appeals. Marc is regularly involved in first-party insurance claims involving catastrophic losses from events like hurricanes, floods, windstorms, and collapses. He also has extensive experience in conventional and artificial (EIFS) stucco coverage litigation and other moisture intrusion cases. During the COVID-19 pandemic, Marc has handled dozens of COVID-19 business interruption claims and represented carriers in subsequent litigation.

Marc frequently assists carrier clients with claims investigations, coverage analyses, examinations under oath, and resulting litigation including litigation over alleged bad faith. He also aids carriers in pursuing pre-litigation settlement through appraisal.

Marc’s experience with third-party claims includes national sports concussion litigation, consumer class actions, construction accidents, construction defects, sexual abuse, and sex trafficking. Carriers often ask Marc to determine whether it has a duty to defend or indemnify the policyholder, and when necessary, he participates in litigation to resolve any outstanding issues.

Marc also has significant experience representing insurance agents and brokers in litigation alleging breach of professional liability. In this capacity, he is engaged in all aspects of the litigation and has been involved in cases defining the scope of a producer’s duty to insureds and third parties.

As a former appellate law clerk, Marc is also involved in many of the appeals that arise at the firm. He represents clients in intermediate New Jersey and Pennsylvania appellate courts, the New Jersey and Pennsylvania Supreme Courts, and the United States Court of Appeals for the Third Circuit. His extensive appellate experience includes jurisdictional challenges, interlocutory appeals, and expedited appeals that often involve complex and novel issues.

As an appellate attorney, Marc also assists trial teams in all practice areas with complex motion practice, evidentiary issues, and litigation strategy. Marc is asked to identify appellate issues and ensure proper preservation of error. He also works to ensure that positive results are unassailable on appeal. His peers routinely ask him to step into ongoing litigation to draft and argue motions on key issues that will profoundly influence the disposition of the case.

Marc has extensive experience in medical malpractice defense, particularly with EMTALA cases. He has also supervised a team of attorneys in discovery matters including productions for large-scale antitrust matters and government investigations.
