Attorney Jack Duggan started his professional life as a detective with the Oak Park Police Department outside of Chicago, Illinois. As a cop, his most common call was for a domestic dispute. As he worked with more and more couples going through these disputes, Jack realized that family law was the perfect avenue to help families going through these tough times before the police had to be called.

Upon graduating law school, Jack started his own practice and practiced law as a solo practitioner. Since he was on his own, he took every opportunity he could to learn the practice of law through volunteering. Specifically, he volunteered with Chicagoland Volunteer Legal Services (CVLS), an organization that advised and assisted new attorneys on how to handle family law matters from beginning to end. He also volunteered with the Illinois State Bar Association by assisting pro se litigants with child supports cases! Since then, Jack has had over 10 years of legal experience in estate planning, landlord-tenant law, mediation, real estate law, family law, and criminal law. Jack even has experience as an intern at the public defender’s office!

Because of his experience, both as a police officer and as an attorney, Jack knows how difficult family law matters can be. He wants his clients to leave his office feeling like they have a true understanding of the legal process. In family law, there are no real winners or losers. There are no days a client is awarded their freedom, like in criminal law, or a substantial amount of money, like in civil law. Knowing this, Jack just wants his clients to know that they are getting the best possible outcome, given the circumstances, and to feel confident in their choice of him as an attorney and Divorce Matters as a law firm.

Outside of work, Jack loves to spend time with his wife and kids! He enjoys coaching as many of his kids’ teams as possible and likes to stay in shape himself by attending CrossFit!
