Brendan Quigley is a former federal prosecutor in the Southern District of New York and an experienced courtroom advocate, having tried a dozen federal jury trials. Since joining Baker Botts, he has focused on SEC and DOJ securities and commodities enforcement matters, FCPA-related investigations and counseling, and matters arising under the False Claims Act, as well as commercial disputes. His clients have included publicly traded and privately held companies, start-ups, executives, and boards of directors in the fintech, energy, transportation, engineering, and financial-services industries. In the last year, Brendan has written and spoken extensively on litigation and enforcement matters involving SPACs and on the intersection between cybersecurity and the securities laws. Before becoming a lawyer, Brendan served for four years as a combat-arms officer in the U.S. Marine Corps, where he first developed the rigor, attention to detail, and tenacity that he uses to help get the best results for clients today.

Immediately prior to 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.

Before becoming a prosecutor, Brendan worked for three years as a litigation associate at another prominent law firm, where he represented clients in the healthcare, financial services, and technology sectors in complex civil litigation and white-collar investigations. Brendan also 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.
