About Hon. John W. Demling
Hon. John W. Demling (Ret.) has spent more than four decades in and around the Illinois legal community. He completed his undergraduate studies in economics at Muskingum College in 1974 and earned his J.D. from Chicago-Kent College of Law, Illinois Institute of Technology in 1977. Those academic years set the stage for a career that has moved between local government and the bench.
Early in his public life he turned to municipal service in Glen Ellyn. He served as a village trustee from 1989 to 1993 and then as village president from 1993 to 1997. Those years in local elected office gave him hands-on experience with municipal operations, budgeting and local governance.
The honorific "Hon." and the parenthetical "(Ret.)" reflect a period on the judiciary. He remains active in organizations that connect former and current jurists, including membership in the Illinois Judges Association. He is also a member of the DuPage County Bar Association, maintaining ties to the county legal community.
Since 2018 he has served in volunteer leadership roles in DuPage County. He sits as a commissioner on the DuPage County Ethics Commission and serves as a director of the DuPage Legal Assistance Foundation. Those positions have kept him engaged in issues of legal ethics, access to counsel and local oversight. His professional affiliations have kept him involved in both the practice and administration of law in Illinois.
In private practice he is associated with Mirabella, Kincaid, Frederick & Mirabella, LLC. That affiliation positions him to draw on his municipal background and judicial experience when advising clients and participating in legal processes. He is admitted to practice in Illinois and continues to be known in DuPage County legal circles.
He combines a background in municipal government, judicial service and county-level nonprofit work. Colleagues describe him as steady and measured in approach, comfortable in court and in public settings alike. His current practice focuses on municipal and administrative matters, and on roles that draw on his experience as a former judge and local official.
