Maderal Byrne & Furst partners have spent substantial portions of their careers as federal prosecutors and criminal defense attorneys and know what works (and what doesn’t) for both. We have tried dozens of criminal jury trials and have argued numerous criminal appeals. This experience makes the difference for our clients.

We represent individuals and organizations under investigation, subject to grand jury subpoenas, or under indictment for white-collar crimes, and in ancillary criminal proceedings regarding extradition and collateral challenges of convictions.

Frank Maderal spent six years as an Assistant United States Attorney in the Southern District of Florida taking on high-profile cases, including as lead prosecutor in some of the largest money-laundering prosecutions in the history of Miami. He led complex local and international investigations and prosecutions against individuals and corporations for corruption, Ponzi schemes, fraud, money laundering, foreign bribery, computer fraud, and Bank Secrecy Act violations. Frank has also lectured federal law enforcement agencies on cyber-crime and complex money laundering investigations.

During his time at the U.S. Attorney’s Office, John Byrne charged over 60 cases, including numerous fraud cases.
