As The New York Times has noted, Mr. Boutrous has “a long history of pushing the courts and the public to see the bigger picture on heated issues.” The American Lawyer named Mr. Boutrous the 2019 “Litigator of the Year, Grand Prize Winner” and the Los Angeles and San Francisco Daily Journals in 2021 named him a “Top Lawyer of the Decade.” According to The National Law Journal, which in 2013 named him one of the “100 Most Influential Lawyers in America,” he “is known for his wise, strategic advice to clients in crisis and is a media law star.”

As both a crisis management strategist and a seasoned appellate and media lawyer, Mr. Boutrous has extensive experience handling high-profile litigation, media relations and media legal issues. He routinely advises clients in planning how to respond, and in responding, to crises and other especially significant legal problems that attract the media spotlight.
