About me

Michael J. Harrison is a former DuPage County DUI and Felony Prosecutor.

I was a former first chair prosecutor with the DuPage County States Attorney's office and I have extensive knowledge and trial experience.

I am also a former Deputy Chief of Police and police supervisor with 20 years experience as a police officer. I am a graduate of the Federal Bureau of Investigation National Academy in Washington D.C..

During my career as a defense attorney, I have handled over 5,000 DUI and criminal law cases including felony DUI and Reckless Homicide cases. Because of my unique experience, I know both sides of the a DUI case and both sides of the legal system. Because of my experience I am able to recognize and take full advantage of any weakness in the prosecution's case for the benefit of my client.

Most importantly, I offer free initial consultation and I invite my clients to call me at any time throughout my representation. This is one of the most difficult and trying times of your life. I understand this. I am always available to speak with my clients throughout their ordeal with the court system.

I offer reasonable rates and payment plans. Because I have a private practice with a select client base you are ensured complete commitment to your cause.
