Message from the
State's Attorney

On behalf of the hard working men and women of the Kane County State’s Attorney’s Office, thank you for visiting and welcome to our Website. I invite you to explore the site and see for yourself the broad array of services performed by the office.

The first priority of the state’s attorney’s office is to represent the interests of our community, which includes you, your family and the people of Illinois in criminal proceedings and to get violent offenders who threaten our safety off our streets. I do not take this responsibility lightly. I believe that there is no higher purpose in government than protecting the safety and welfare of the citizens whom I have been entrusted to serve. The men and women of the state’s attorney’s office have dedicated themselves to this duty. Whether it is an attorney in our Criminal Division prosecuting a violent criminal, a counselor in our Diversion program providing rehabilitative services to a non-violent offender, or an attorney in our Civil Division collecting unpaid child support, making sure that the children of Kane County have a safe and healthy place to live or representing the County of Kane in legal proceedings and transactions, everyone in our office works diligently on a daily basis to make our community safer and preserve the quality of life we enjoy in Kane County.

I hope you find the information contained on the Website useful and informative. You will find explanations of our many diversion programs and contact information for those divisions. Additionally, I have included links to the Websites of our partners in the criminal justice system, from local law enforcement to state and federal agencies. I continue to work hard to make this State’s Attorney’s Office and our entire criminal justice system as user friendly as possible. Ultimately this is your county and your state’s attorney’s office, and I need the assistance and trust of the community to solve our crime problems. Everyone has a stake in public safety.

As state's attorney, it is my job to hold people accountable for the crimes they commit, but it is everyone's dute to work to prevent crime.  If we really want to solve our crime problem, we must stand united with one clear, strong voice and tell the criminal element that they do not have a safe haven on the streets of Kane County.

I thank you for the opportunity to serve the people of this great county.
