Jeffrey D. Muntz


Aurora parenting time lawyers
Best 10 Criminal Best 10 Family Emerging Lawyers Lead Councel Elite Lawyer Badge

An equity partner at Goostree Law Group, Jeff sensed a career as an attorney was his destiny during his high school days. One time, he received the results from a Spanish test, and when he confronted his teacher over his grade, the instructor advised him to become a lawyer because of his willingness to argue about anything. Jeff's parents could not disagree and offered the same advice due to his fervent and detailed arguments over his bedtime and curfew.

Growing up, Jeff saw the effects that crime had on his small community that was unaccustomed to criminal activity. What he witnessed led to his pursuit of a career in the law. He took pre-law classes at Saint Ambrose University, which led to an internship with the State's Attorney's Office in Bureau County, where he spent a semester with the county prosecutor. After graduating cum laude, he attended the Valparaiso University School of Law and studied abroad at the University of Cambridge in England.

Jeff joined the DuPage County State's Attorney's Office as a prosecutor in 2004 and handled complex felonies, including sexual assault and first-degree murder cases. He was an admired leader in the office, and in 2006 was honored as its outstanding misdemeanor prosecutor, with a tough-but-fair reputation that earned the respect of defense attorneys and judges.

In 2012, Jeff decided to pursue a career in domestic relations and family law, which was similar to his previous career stop and suited his passion for helping others. Since then, his practice has focused on litigation of complex divorces, spousal maintenance, and disputes regarding the allocation of parental responsibilities (custody). He brings a professional, committed, and compassionate approach to every case, along with impeccable integrity. With his small town and overseas experience and previous work with crime victims and law enforcement, he relates to all types of people and scenarios. His love for the courtroom remains as strong as ever, as does his devotion to finding resolutions to legal issues of all kinds.

With his extensive time as a prosecutor, Jeff also maintains a significant criminal defense practice and has prevailed in cases in DeKalb, DuPage, Kane, and Kendall Counties. If you face a charge for anything from a traffic citation to a felony, having a longtime former prosecutor as your attorney is a good legal strategy.

Jeff enjoys his leisure time with his wife and children and loyally viewing his beloved sports teams in person or on TV.
