As a prosecutor, I watched some of the brightest and best-intentioned individuals and companies make poor decisions when they became the subject of criminal, civil or administrative investigation. Now as a private-practice lawyer, I am determined to help clients avoid such missteps. I know the real-world implications of investigations and criminal prosecutions, and I fully appreciate the fact that your liberty, reputation and livelihood are at stake.

Brian Lennon specializes in criminal defense – particularly of health care fraud and other white collar and drug offenses, as well as corporate internal investigations and compliance matters. For False Claims Act matters, a distinct focus, he also provides civil defense, and expects to see a number of cases soon arising tied to the receipt (and alleged misuse) of Paycheck Protection Program (PPP) funds. Brian works with clients in all corners of Michigan and represents a significant number of professional service providers in the Detroit area.

“My experiences as a federal prosecutor and trying cases for the DOJ bring valuable perspective and insights to clients needing to hire our criminal practice at Warner,” he explains. “I am not afraid to try cases and prosecutors know that — which helps our clients’ positions.”
