Best Lawyers named David “Lawyer of the Year” for White Collar Criminal Law in 2020 and for General Criminal Defense in 2017. And the Dade County Bar Association awarded him the “Legal Luminary” award for criminal defense, an honor voted on by members of the legal community. In 2015, the National Law Journal selected him as one of the Trailblazers for White Collar Criminal Defense in the entire country. Back when he was 29 years old (in 2002), the National Law Journal selected him as one of the top 40 litigators in the country under 40 years old, and it has recognized one of his federal trial victories as one of the top ten defense verdicts in the country that year.
In one trial victory, David not only beat all 141 counts in federal court for a doctor, but then won attorneys’ fees and costs of over $600,000 for his client in a first-of-its-kind victory. Based on that case, he was awarded the highest honor — the Rodney Thaxton “against all odds” award — by the Florida Association of Criminal Defense Lawyers. Although the 11th Circuit reversed the fee award in a number of controversial opinions, the court referred to Markus as an “elite” and “superb” attorney. (See page 9 of the opinion here). In another case, David challenged the way the federal court system in Miami selected jurors (alphabetically by last name) and won, which changed the jury selection process in the District (click here). After obtaining a fair jury, Markus’ client was found not guilty. He never stops fighting for his clients.

Based on this type of creative and unique lawyering, in 2010, David was one of eight finalists in the country for best white-collar criminal lawyer in the country by Chambers & Partners, which quoted market sources saying that David is “the whole package,” and “a creative, courageous and tenacious courtroom advocate.” And he was named to that very prestigious short list of 8 best white-collar criminal defense lawyers again in 2011 (he was the only lawyer listed who was not from a large firm). The 2012 Chambers said this: “David Markus received strong praise from peers and clients alike, who describe him as ‘a legal genius and brilliant strategist with a great demeanor.'” A recent Chambers & Partners described David as a “wickedly smart and a terrific trial lawyer. … Clients say that he is ‘thrilling’ to watch in court and that ‘his passion appreciation and enjoyment for his work are contagious.” And in 2014, that publication identified David as “one of the best trial lawyers around: very smart, highly respected and thoroughly prepared.” In 2016, Chambers said: “David Markus is one of the most talented criminal defense lawyers in Florida. He has a wealth of litigation experience and is regularly sought after for his counsel in high-stakes tax and criminal antitrust cases. Sources also describe him as an ‘extremely creative thinker and a great oral advocate’ who gets ‘tremendous results.'” Chambers has also explained: “David Markus is amazing, not only because of the strength and genius of his arguments and motions, but also because of his brilliant and astonishing performances during the hearings. Additionally, he radiates so much confidence, and that in itself soothes the usual anguish and anxiety that you endure during these types of situations. Last but not least, he is such a great human being.” In 2020, that publication said that David “is an exceptional trial lawyer,” “an incredible oral advocate” and that “he’s pretty fearless in terms of dealing with the government.”
Since 2010, David has been listed as one of the top 100 lawyers in Miami and in all of Florida by SuperLawyers. He is one of the few criminal defense lawyers to received such an honor. He is frequently named as one of the top lawyers in the Best Lawyers in America, South Florida Legal Guide, Florida Trend Magazine, Chambers & Partners, and the South Florida Business Journal. He was one of 20 lawyers named a key partner by the South Florida Business Journal in 2011 and again in 2012. The Daily Business Review named him a finalist for Most Effective Lawyer in Criminal Justice (one of three lawyers in Miami) in 2006, 2009, 2011, 2012, and 2015. He won the award in 2018. The district judges in the Southern District of Florida presented him with the Eugene Spellman Criminal Justice Act Award in 2013.
While at Harvard, David argued in front of Supreme Court Justice Anthony Kennedy who named him best oralist. (The argument, which was carried on C-Span, can be viewed here. David’s argument begins at 57:42). David was mentored by Alan Dershowitz while in law school (click here for a picture of them together at Harvard). After graduating from Harvard, David served as law clerk to the Honorable Edward B. Davis, then-Chief United States District Judge, Southern District of Florida. Following his clerkship, David worked as an associate at the leading criminal defense firm in the country, Williams & Connolly in Washington, D.C., and then practiced as an Assistant Federal Public Defender in Miami.
