Jeff Marcus

Jeff Marcus is a highly regarded trial lawyer and former federal prosecutor whose practice focuses on high stakes white collar and civil litigation.  Jeff is known as a creative and tenacious litigator whose skills shine in difficult cases.  This year, he was one of a small group of Florida lawyers ranked in the top band for litigation and white collar defense by the prestigious Chambers USA.   In those rankings, Jeff has been described by peers and clients as an “extremely effective” trial lawyer with a “keen eye for understanding the dynamics and strategy of a case,” who “brings high intellect,” “superb” writing skills and “a thorough and conscientious approach to all his cases.”  Jeff also has been recognized by a wide range of other peer groups and publications, such as Best Lawyers of America, as a top lawyer.

Jeff’s out-of-the-box approach has built a reputation for excellence in and out of the courtroom.  In his white collar practice, Jeff successfully has represented individuals and companies in many high-stakes matters that never see the light of day to the delight of his clients.  In one multi-year investigation,  Jeff secured a full declination of all charges and penalties for a Fortune-100 company, which was the target of a criminal RICO and fraud probe, after making a series of presentations  casting  doubt on the statistical methodology the government used to develop its allegations of fraudulent billing.  In another recent probe, Jeff recently obtained a full declination from the Department of Justice for a nationally-prominent physician accused of performing unnecessary surgical procedures.  To clear his client, Jeff put together a team of top medical experts and rebutted the allegations with state-of-the-art medical presentations.

In court, Jeff does not back away from a fight.  Just within the past year, Jeff tried three lengthy and difficult high-profile federal white collar cases, and, in each one, obtained dismissals on a majority or more of the charges.  In one notable victory, after more than 3 months of trial, Jeff won an acquittal on all eleven federal kickback and fraud charges for his client, a district manager for a Fortune-500 pharmaceutical company.  More recently, Jeff obtained a dismissal with prejudice on all claims against his client in a federal qui tam case.

Jeff’s practice experience spans a wide variety of industries where he has defended professional sports franchises and athletes, military and private security contractors and executives, financial institutions and officers, healthcare and pharmaceutical companies and executives, politicians and city officials, media and entertainment companies and executives, real estate corporations and officers, law firms and lawyers and hospitals and physicians in both criminal, regulatory and internal investigations.  Jeff also is well versed in conducting internal investigations on behalf of publically-traded and privately-held businesses.  Jeff also has been retained as a subject matter expert in fraud and securities matters, including being designated as an expert witness in securities fraud litigation in Texas federal court on behalf of the court-appointed receiver overseeing the former Stanford Financial Group which ran one of the largest Ponzi schemes in U.S. history.

In his civil practice, Jeff represents both plaintiffs and defendants in a variety of settings from federal and state courts to AAA and FINRA arbitrations.  Jeff regularly handles “bet the company” commercial and partnership disputes as well as complex matters in the areas of business torts, civil Rico, healthcare, financial fraud, securities, and qui tam.

Prior to being a Founding Member of Marcus Neiman & Rashbaum LLP, Jeff was a shareholder at Kenny Nachwalter P.A. where he headed the firm’s White Collar Practice and before that was a federal prosecutor in the Southern District of Florida’s Criminal Division.  As an AUSA, Jeff successfully tried more than 25 cases to verdict and briefed and argued numerous appeals before the U.S. Court of Appeals for the Eleventh Circuit.  Jeff specialized in economic crimes, and was a healthcare fraud coordinator, where he led numerous investigations involving hospitals, health care providers, pharmacies, laboratories, and companies involved in the manufacture, sales and distribution of pharmaceuticals, medical devices and durable medical equipment.  Prior to joining the government, Jeff practiced with Eckert Seamans in Boston, Massachusetts where he specialized in white collar and complex commercial cases.

Raised in Miami, Florida, Jeff graduated magna cum laude from Yale University where he received the honor of “early selection” into its Phi Beta Kappa chapter.  He then earned his J.D. from Yale Law School where he won best oralist and was a finalist for best written brief in the Harlan Fiske Stone moot court competition presided over by a panel of federal judges.  After law school, Jeff clerked for the Honorable Stanley Marcus of the United States Court of Appeals for the Eleventh Circuit (no relation) and the Honorable Donald M. Middlebrooks of the United States District Court for the Southern District of Florida.  Jeff has taught constitutional criminal procedure and legal writing at the University of Miami and lectures nationally on litigation and white collar topics.

Outside of work, Jeff serves on the Executive Committee and Board of Directors of Temple Beth Am and the Executive Board of Dunks for Diabetes, a national non-profit that raises money for diabetes research and outreach, in partnership with the American Diabetes Association, through charity basketball events.  Jeff also volunteers and helps run Beth Am’s large community youth basketball league where he also coaches his two sons.
