Government Investigations/Enforcement: Brendan's government investigations practice draws on his experience as a former senior member of the Southern District of New York's Securities and Commodities Fraud Unit and its Terrorism and International Narcotics Unit. He focuses on matters involving the securities and commodities laws, international transactions, and the False Claims Act. He has represented clients in front of government regulators including the Department of Justice (including the Criminal Division Fraud Section, the Civil Division Fraud Section, the National Security Division, and numerous U.S. Attorney's Offices), the New York Attorney General, the Manhattan District Attorney's Office, and the Securities and Exchange Commission.

Commercial Disputes: Drawing on his experience of having a first-chair role in over a dozen trials, Brendan also represents clients as both plaintiffs and defendants in commercial disputes. These matters often involve complex transactions and/or allegations of fraud or corruption. In 2023, for example, Brendan prevailed at trial in the Delaware Court of Chancery in a dispute among shareholders of a closely held corporation. In 2022, he was a key member of a team that prevailed in an intercreditor indenture litigation in federal bankruptcy court.
