Brendan M. Walsh

Brendan Walsh serves as co-chair of the firm's Litigation department and is a member of the firm's Executive Committee. Brendan is an accomplished litigator whose clients range from Fortune 500 corporations to high-net-worth individuals and closely-held companies. Clients appreciate his creative thinking, commitment to protecting their interests, and diligence. Brendan is a skilled writer who can distill complex legal and factual issues into arguments that can be easily understood.

Along with 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. He recently secured a complete victory in the Second Circuit for a global restaurant chain involved in a complex commercial real estate dispute. He 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.

Brendan has authored amicus briefs to several 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. Before 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. Earlier in his career, 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. As an undergrad 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.

Brendan is proud of the results he has achieved for clients, some of which are noted here and under the “Experience” section of this biography.  Of course, each legal matter is unique on many levels, and past successes are not a guarantee of results in any other pending or future matters.
