Before entering private practice, Mr. Brown served as both a Special Agent and Legal Advisor with the Federal Bureau of Investigation.

Today, Mr. Brown leads Brown, LLC’s national litigation practice and remains actively involved in case strategy, major negotiations, depositions, trials, and significant whistleblower matters. The firm has become one of the country’s more active False Claims Act practices, with Lex Machina ranking Brown, LLC as the second most prolific firm in False Claims Act filings over a five-year period.

Mr. Brown is selective in the matters he accepts and concentrates his practice on litigation in which substantial rights, significant financial interests, or important public interests are at stake. He approaches those matters with the investigative discipline of his federal law-enforcement background and the perspective developed through decades of complex litigation
