Andrew Wirmani is an experienced, go to trial lawyer and former federal prosecutor. Between private and government practice, he has successfully tried numerous high-profile civil and criminal cases to verdict. In 2021, Wirmani played a prominent role as trial counsel in securing a $36 million trial win with mandatory trebling ($108 million) in a False Claims Act case involving procurement fraud, U.S. ex rel. Marsteller v. MD Helicopters, Inc. The case was recognized by the National Law Journal as one of the top 100 verdicts in the country and by Top Verdict as both a top 100 verdict and the top verdict in the False Claims Act category. In 2024, Wirmani and his colleagues from Reese Marketos prevailed in a two-month jury trial against Janssen Pharmaceuticals alleging anti-kickback and off-label marketing violations. The jury verdict resulted in a record breaking $1.6 billion judgment. Wirmani is also currently defense counsel in two of the largest healthcare fraud criminal prosecutions pending in Texas. While with the Department of Justice, Wirmani led the investigation and two-month trial of the Forest Park Medical Center case, one of the largest most successful healthcare prosecutions in Texas history.
Wirmani leads Reese Marketos’ white collar defense practice and has deep expertise in healthcare matters, including fraud enforcement and investigations. He also represents whistleblowers in False Claims Act cases and companies and individuals in high-stakes business disputes, both on the defense and plaintiff’s sides.
