DuPage County Criminal Defense Attorney

Aggressive Defense Against Serious Criminal Charges

At The Law Office of Mark E. Kowalczyk, I represent clients in serious criminal matters.

To schedule a consultation with me to discuss your case, contact me by e-mail or call 630-984-5830.

Navigating the Criminal Justice System

I practice exclusively in Illinois criminal courts. I served as an Assistant Attorney General for the State of Illinois and as First Assistant Attorney in both Kane County and DuPage County. In part due to my extensive experience, I am certified to act as lead defense counsel in capital cases by the Capital Litigation Trial Bar. My knowledge of the criminal justice system allows me to present a vigorous defense for my clients. I can help take the confusion and anxiety out of the process.

My Services

From cases involving violent crimes and drug charges, to allegations of DUI and Internet crimes, I provide my clients with personal attention and dedicated service. I have seen first-hand how a single mistake can destroy a person's future. Everyone makes mistakes. I view it as my job to protect my clients by minimizing the impact of those mistakes. If you need an Illinois DUI attorney or aggressive representation against a drug possession charge or any other criminal charge, I have the experience and skill to help you.
