A high-powered, high-profile white collar crime lawyer

A graduate of Harvard Law School, Mr. Wynne has built an impressive record of success in both state and federal courts.

His practice is passionately devoted to protecting the rights of public and private corporations and businesspersons.

Previously, he represented individuals, corporate fraud victims, profit and nonprofit businesses and other entities in federal criminal and civil litigation and health care matters as a partner at McDermott, Will & Emery.

A seasoned defender familiar with the best prosecutor's mindset

If you’re facing criminal charges, the best person for the job is someone with extensive experience on the other side of the courtroom. Mr. Wynne served as an assistant U.S. attorney for more than 12 years, representing the U.S. in several hundred large investigations and trials in the Southern District of Texas and elsewhere. Through this work, he collaborated with practically every federal and state investigating authority, including the FBI, IRS, DEA, ATF, Health and Human Services OIG, Department of Defense, NASA OIG, Secret Service, U.S. Postal Inspection Service, Homeland Security, Customs and Border Patrol, Texas Rangers, U.S. Marshal Service, the Department of State, SEC, State Securities Board, and multiple foreign governments.

Mr. Wynne was the first-chair federal prosecutor in major public corruption cases, including the prosecution of congressional candidate Armando Villalobos. As the lead prosecutor in the high-profile Denison 11 case, he played a central role in the prosecution of the individuals involved in a smuggling operation that killed 11 immigrants. He discussed this hard-fought accomplishment in a 2014 episode of “The Hunt With John Walsh.” He also led the nationwide crackdown on multiple large, international child pornography distributors, resulting in 90 arrests in the highly-public “Candyman” prosecutions.

With a unique firsthand understanding of the strategies employed by prosecutors, Mr. Wynne knows what you’re up against and stays one step ahead of your opponents. Let Mr. Wynne’s unmatched expertise work for you and your defense strategy.

  • Recently, Michael represented my son on a sensitive matter that had potential criminal repercussions. The matter required an evaluation of criminal liability , strategizing on the best approach to handling a defense, and engaging with federal authorities at both the FBI and DOJ. Michael's previous experience as a AUSA and his track record of representing clients in white collar criminal proceedings proved utterly invaluable. Through a series of discussions with the FBI agents assigned to the case as well as the AUSA, the matter was resolved quickly without any charges being brought. Throughout the process, Michael was a great communicator, was honest and frank about the issues involved, and very focused on getting the outcome that ultimately resulted for my son. I can recommend him without reservation as a trusted and highly skilled legal counsel.
