Brendan M. Walsh, The Stein Public Interest Center Photo


Brendan Walsh focuses his practice on complex civil litigation and white collar criminal defense, and handles sensitive legal matters such as internal investigations arising from allegations of sexual harassment. He is an accomplished litigator whose clients range from global food and beverage corporations to cross-border banking institutions, to regional multifamily property owners and specialized medical practices. Clients appreciate Brendan’s creative thinking, commitment to protecting their business interests, and diligence.

In addition to his trial court work, Brendan has substantial appellate experience, having successfully briefed and argued appeals in the U.S. Courts of Appeals for the Second and Third Circuits, and the Appellate Division of the Superior Court of New Jersey. Brendan is a skilled writer who has the ability to distill complex legal and factual issues into arguments that can be easily understood. He recently secured a complete victory in the Second Circuit on behalf of a Fortune 500 company involved in a complex commercial dispute. Brendan also obtained reversals in two separate Third Circuit appeals, one challenging the constitutionality of a prison’s intrusive search policy of inmates housed in isolation units and another challenging a trial court’s order compelling the production of thousands of privileged documents from an attorney’s work files.

He also has authored amicus briefs to a number of appellate courts, including the Supreme Court of the United States, the Supreme Court of New Jersey, and the U.S. Courts of Appeals for the Third and Tenth Circuits.

Brendan brings substantial business experience to his litigation practice. Prior to attending law school, he worked as a certified public accountant at Deloitte, where he provided audit and advisory services to a diverse group of clients around the world, including other accounting and consulting firms, manufacturers, retailers, and a professional sports franchise.

Before joining Pashman Stein Walder Hayden, Brendan was a litigation associate at Patton Boggs LLP. Previously, he clerked for Judge Maryanne Trump Barry of the U.S. Court of Appeals for the Third Circuit and for Judge Katharine S. Hayden of the U.S. District Court for the District of New Jersey. While attending college at the University of Notre Dame, Brendan worked as the head manager of the Notre Dame football team, an experience he credits with further developing his strong work ethic, dedication, leadership, and collaborative approach.
