Described by the Los Angeles Daily Journal as a "legal titan", and by Chambers as a "known litigation genius", John B. Quinn is one of the most prominent business trial lawyers in the United States. As Chambers put it in their 2007 guide to U.S. lawyers and law firms: "'Tough guy' John Quinn is 'confident and quick' say clients. Opponents acknowledge his 'convincing courtroom demeanor' and one even named him 'literally the best I have ever faced in the past half dozen years.'" This sentiment echoed The American Lawyer's 2006 feature article, which described the Am Law 100 firm that Mr. Quinn built from scratch as "Better. Faster. Tougher. Scarier". ("The Mighty Quinn, John Quinn Is in Better Shape Than You Are. Now He Wants to Eat Your Lunch", The American Lawyer, 2006.) Or, as further summed up by his clients in Chambers—"there is no other".
