About The Sullivan Firm

Our team is skilled, experienced and aggressive – the type of attorneys you want representing you or your business. We take pride in being highly respected and admired by peers, judges and the media as persistent supporters for those charged with a vast array of crimes.

We understand that being charged with a crime is perhaps the most terrifying experience anyone ever can have and that you need a warrior in the court to get through it. Through comprehensive pretrial groundwork and preparation, we have managed to get hundreds of cases terminated.

We also have an entire team dedicated to injury.

Lead attorney Terry Sullivan has been in private practice since 1982. A respected criminal attorney, he has extensive experience as a Cook County State’s Attorney, prosecuting and successfully convicting high-profile cases like John Wayne Gacy and Patricia Columbo.

He has also appeared before a United States Senate Select Committee, testifying on juvenile justice.

Terry is firmly committed to continuing legal education and community service. This can be seen in his pro bono work as the Media Liaison on cases like R-Kelly, The Brown’s Chicken Massacre, William Balfour and Officer Jason Van Dyke. Terry has been a familiar face to may many who look to Chicago’s WGN for their news. He has a 20-year stint as their legal analyst and has covered cases from Drew Peterson to the Boston Bombings.

Terry has consistently been named one of the Top Ten Criminal Defense Lawyers in Illinois by the Leading Lawyers Network.
