Described by Chambers as a “real trial lawyer,” “a giant in the legal community,” and a “creative thinker and problem solver,” Brian Hennigan is the managing partner of Hueston Hennigan LLP. Consistently rated as one of the nation’s top trial lawyers, Mr. Hennigan was recently recognized as a “California Lawyer of the Year” for his representation of the University of California Board of Regents in a matter related to an audit of the state university system.

Over the course of his career, Mr. Hennigan has specialized in complex litigation, with an emphasis on white-collar criminal defense and investigations. For more than 20 years, he has successfully represented individuals and corporations facing a wide array of challenges presented by federal prosecutors and investigating agencies. Recent matters have resulted in the successful representations of individuals facing allegations under the Foreign Corrupt Practices Act, the Securities and Exchange Commission Act, the Internal Revenue Code, and the Sherman Act. He has also represented Fortune 500 corporations in a variety of civil disputes, including antitrust, trade secret, and unfair competition litigation.

Mr. Hennigan is regularly engaged to represent a variety of institutions, corporations, professional athletes, leaders of various religious denominations, doctors, lawyers, accountants, and business executives in federal and state matters. For example, Mr. Hennigan currently represents a corporate executive indicted in a pending DOJ antitrust case concerning allegations of price fixing by Korean fuel suppliers to the U.S. military; successfully concluded his representation of the Archdiocese of Los Angeles in a civil case in Los Angeles Superior Court; and concluded his representation of a client in a three-year-long grand jury investigation with no criminal charges filed. 

Mr. Hennigan is a Fellow of the American College of Trial Lawyers, an honor reserved for less than 1 percent of active lawyers who have “mastered the art of advocacy and whose professional careers have been marked with the highest standards of ethical conduct, professionalism, civility, and collegiality.”

Mr. Hennigan has earned significant praise from clients and colleagues for his white-collar practice. Chambers USA has ranked him in Band 1 every year since 2008 in the White Collar Crime & Government Investigations category, lauding him as a “creative thinker and problem solver” and “a terrific attorney because of his great ability to communicate with judges and juries.” Legal500 recently recognized him as a leading lawyer and a “Hall of Fame” lawyer. In 2019, Mr. Hennigan was honored by the Loyola Law School Innocence Project as a Lawyer of the Year for his work in obtaining the release of Maria Mendez, a criminal defendant who was wrongfully convicted by the Los Angeles District Attorney’s Office. Benchmark Litigation has also recognized him as a “Top 20 Trial Lawyer in California” and named him among the “Top 100 Trial Lawyers in America.”
