Brendan Quigley has taken over a dozen cases to verdict or final decision, and he led numerous complex investigations during his seven years as an Assistant United States Attorney in the Southern District of New York. As a result, he knows what matters to regulators, to judges, and to juries. He helps clients prevent problems before the government or private litigants come knocking by advising them on the design and implementation of compliance programs. And when an issue does arise, Brendan draws on his advocacy skills and his proven ability to litigate a case all the way through the finish line to achieve the best possible results. Indeed, some of Brendan's proudest results in private practice have come when he has persuaded the government not to bring public charges against clients.

Before becoming a lawyer, Brendan served for four years as a combat-arms officer in the U.S. Marine Corps, where he honed the rigor, attention to detail, and fortitude that he uses to help his clients today.

Government Investigations and Compliance. Drawing on his experience as a senior member of the Southern District of New York’s Securities and Commodities Fraud Unit and its Terrorism and International Narcotics Unit, Brendan's government investigations practice focuses on matters involving potential or alleged violations of laws concerning fraud, corruption, and national security. He regularly represents clients in investigations arising involving the Foreign Corrupt Practices Act, the False Claims Act, and federal securities laws and regularly counsels clients on compliance matters in those areas and in connection with the U.S. sanctions program.

Commercial Disputes. Drawing on his extensive first-chair trial experience, Brendan also represents clients in commercial disputes in federal district courts, federal bankruptcy courts, and New York State courts and in arbitration proceedings. These disputes often arise out of complex transactions. For example, Brendan was a key member of the team that prevailed in an intercreditor indenture litigation in the summer of 2022 challenging our client’s issuance of certain notes before its bankruptcy. He also represents clients in matters involving alleged fraud or corruption and prevailed on a motion to dismiss in New York state court in a case alleging a complex financial product was sold in violation of the federal securities laws.

Earlier in his legal career, Brendan spent a year clerking for the Honorable Joseph F. Bianco, then a U.S. District Judge in the Eastern District of New York, now of the Second Circuit.

Between 2001 and 2005, Brendan served as an officer in the U.S. Marine Corps. He completed two tours of combat duty in Iraq and was honorably discharged with the rank of Captain.
