For Everyone
23 years in law enforcement. 8 years on the DuPage County Board. A lifetime of service to our community.
Proven Experience
Leadership You Can Trust
I know firsthand the hard work, courage, and heart it takes to wear the badge with honor. I have served as a patrol officer, supervisor, and leader working alongside municipal departments across DuPage County.
I also spent eight years as an elected County Board member — approving budgets, reviewing staffing, and holding departments accountable. That combination of operational experience and fiscal oversight is what this office demands.
“Leadership is not about being the best. Leadership is about making everyone else better.”— Sean Noonan
