He has more than three decades of diverse legal experience including roles on the bench, in private practice, and as an assistant circuit attorney for the city of St. Louis. Most recently, serving as a circuit judge in the Missouri 22nd Judicial Circuit Court, Michael presided over a number of high-profile, multi-week and multimillion-dollar trials.

Michael brings his in-depth insight into the workings of the court to his client representations, having tried hundreds of cases and presided over countless others, both bench and jury trials, involving felonies as well as high-value civil disputes. He has rendered dozens of opinions described as well-reasoned and adhering closely to precedent as well as to constitutional and statutory law.

During his time on the court, Michael established St. Louis’ Criminal Justice Coordinating Council, comprised of intergovernmental agency leaders working to enhance public safety through coordinated decision-making; and the city’s felony redirect program, allowing people with low-level felonies to enter alternative rehabilitation programs.

A sought-after speaker and panelist, Michael has appeared at national mass tort conventions as well as the Missouri Organization of Defense Lawyers, Missouri Association of Trial Attorneys, the Bar Association of Metropolitan St. Louis Bench and Bar conference, and numerous CLE programs.
