John R. Kopp is a 2008 graduate of the John Marshall Law School in Chicago, Illinois. He attended Marquette University in Milwaukee, Wisconsin, where he earned a degree in communications. He grew up in Aurora, Illinois, and attended Marmion Academy.

Mr. Kopp evaluated the strengths and weaknesses of each case he prosecuted for the Cook County State's Attorney Office. When he encountered a weakness, he placed himself in the position of the defense lawyer so that he could best prepare himself for arguing the prosecution's case.

Many of his cases involved preparing police officers for their testimony at trial. Through that process in hundreds of trials, Mr. Kopp gained a thorough grasp of police investigations, warrant executions and arrest procedures. With that knowledge, he can attack the shortfalls and errors the police made in their case against you.

Mr. Kopp is an experienced litigator who is ready to defend your rights.
