The American Lawyer honored Dan as the 2020 “Litigator of the Year,” noting that he “is a lawyer clients call in the toughest situations,” and the Daily Journal selected him among its “Lawyers of the Decade.” Legal 500 ranks Dan as one of the country’s top 10 trial lawyers and selected him as the winner of its inaugural “Leading Trial Lawyer of the Year,” describing him as an “excellent, excellent trial lawyer” in a “whirlwind year which saw him try a slew of different matters back-to-back across various industries.” Chambers USA ranks Dan as a leading lawyer and quotes sources who say he is “a first-rate trial lawyer” and “a fantastic force,” “the one you hire for bet-the-company cases” who is “highly in demand.” Clients compliment him for being “very strategic, very good in court and very client-focused.” Dan has also been recently recognized by Billboard Magazine as a “Top Music Lawyer,” Variety as one of the industry’s “50 Game-Changing Entertainment Attorneys,” The Hollywood Reporter as a “Power Lawyer,” Benchmark Litigation as a “Trial Lawyer of the Year,” The National Law Journal as a “Winning Litigator,” and by Law360 as a “Media & Entertainment MVP.” Dan is a frequent national commentator on trials and other legal issues, as well as a featured speaker on legal issues at business groups, bar and judges associations, and citizens groups.
