Brendan F. Quigley, Esq.

Brendan Quigley is a former federal prosecutor in the Southern District of New York and an experienced trial lawyer. He represents organizations and individuals in government and internal investigations and complex civil litigation, including securities enforcement matters and matters arising under the Anti-Terrorism Act and the False Claims Act. Brendan draws on his extensive courtroom experience, his decade-plus of litigating complex cases, and judgment and tenacity first honed as a combat-arms officer in the U.S. Marine Corps to deliver the best possible results for clients. 


Before joining Baker Botts, Brendan spent almost seven years as an Assistant United States Attorney in the Southern District of New York (SDNY), becoming a senior member of the Office's Securities and Commodities Fraud Unit and one of its most seasoned trial lawyers, trying 12 cases to verdict. Brendan also briefed or argued over ten appeals in the U.S. Court of Appeals for the Second Circuit. 


While at the SDNY, Brendan investigated and prosecuted numerous complex and high-profile matters. These included a racketeering and securities fraud prosecution arising out of the world's largest-ever private equity insolvency, the prosecution and trial of a prominent New York media personality for securities and wire fraud, and multiple other matters involving insider trading, accounting fraud, market manipulation, and investment adviser fraud. In many of these cases, Brendan worked closely with civil regulators, including the SEC, the CFTC, and FINRA. 


Brendan also served in the SDNY's Terrorism and International Narcotics Unit, gaining significant experience in cross-border and national-security related investigations, including matters involving cybercrime, espionage, money laundering, and foreign political corruption.
