As a former Assistant Attorney General for the State of Illinois and First Assistant Attorney in both Kane and DuPage counties, I know how prosecutors approach criminal cases. I have built a reputation in the legal community as an honest, trustworthy and aggressive legal practitioner. I fight for my clients and work to minimize the consequences they are facing. Over the years, I have earned the respect of the people who work in the Illinois criminal justice system.

My experience and my approach help to ensure that my clients are always treated with respect. No one wants to be accused of a crime. To protect yourself through this difficult time, you need someone on your side who understands the process and can defend you every step of the way. Whether you are charged with a white collar crime, such as fraud, or drug possession, you need an advocate to give you the aggressive representation you deserve.
At The Law Office of Mark E. Kowalczyk, I provide skilled criminal defense representation in Illinois courts. Call 630-984-5830 for a free consultation.

The Law Office of Mark E. Kowalczyk – Providing services in the following areas of law:

Violent crime

— I am certified by the Capital Litigation Trial Bar to act as lead defense counsel in capital cases. Few attorneys have the experience and skill necessary for this certification. Whether your case involves domestic violence defense, or charges of aggravated assault or murder, you need an attorney with trial experience to protect your rights.


Drug crime

— Drug possession, drug trafficking, drug manufacture and conspiracy charges carry serious penalties. The consequences of a conviction can be life-long. An aggressive criminal defense lawyer can help you understand what you are facing and create a strategy to fit your situation.

Driving under the/ influence

— If you have been arrested on Illinois drunk driving charges, you face the loss of your license, significant fines, and even time spent in jail. I can help you protect your rights after drunk driving charges.

Sex crime

— Most crimes involving sexual conduct carry mandatory prison sentences and registration as a sex offender. A strong defense is vital when you are facing charges relating to Internet sex crimes, sexual assault, solicitation, possession of child pornography or other sex crimes.
