About me

I have been in practice for over 20 years and have tried hundreds of cases to verdict, representing clients in both criminal and civil matters, including but not limited to: DUI, felony and misdemeanor criminal defense,  personal injury, including automobile accidents, dog bites, slip and falls, wrongful death and medical malpractice as well as other civil litigation. I have represented both plaintiffs and defendants, as well as petitioners seeking reinstatement of their drivers licenses.


I am honored that many of my clients are referred by previous clients and fellow attorneys, and to have been rated as one of Chicago's Top Three DUI Attorneys, one of Illinois' Top Ten DUI Lawyers and one of Illinois' Top 100 Trial Lawyers.


I am a member of the Chicago Bar Association, Illinois Bar Association, the Illinois Association of Crminal Defense Lawyers and the Illinois Lawyers and Substance Abuse Counselor's Association.
