Major Michigan Cases That Shaped My Career
Over the course of my career — both as a prosecutor and now as a defense attorney — I’ve been involved in several high-profile cases that helped define my approach to criminal law. Each case reinforced one simple truth: every client deserves an advocate who knows how to navigate Michigan’s most complex legal battles.

People v. Sam Riddle
This widely covered homicide case remains one of metro Detroit’s most recognized trials. As part of the prosecution, I worked to ensure that justice was served in a case that drew intense media attention and public scrutiny. It was an experience that taught me the importance of precision, preparation, and fairness in the courtroom.
The McCotter Petition-Fraud Case
Years later, I found myself on the other side of the aisle — defending one of the staffers accused in the 2013 petition-fraud case connected to former Congressman Thaddeus McCotter. Our team successfully argued for reduced charges, emphasizing due process and proportionality in sentencing. It was a powerful reminder that defense work is about protecting not just clients, but the integrity of the justice system.
Local and Federal Defense Work
Beyond headline cases, I’ve handled hundreds of criminal defense matters — from DUI and assault to federal healthcare investigations. Every case, no matter its size, deserves the same commitment to strategy and results. My experience in both state and federal court has given me a balanced understanding of how to defend clients effectively in Michigan’s legal system.
Justice is not automatic — it’s earned through preparation and advocacy.
