Maria G. Antoniolli, or “Gabby,” grew up in DuPage County, attending Hinsdale South High School in Darien. She went on to attend the University of Illinois Urbana-Champaign, where she received a Bachelor of Arts degree in Political Science and English (minor). After graduation in 2004, Gabby was hired by the DuPage County State’s Attorney’s Office where she worked as a legal secretary for one year prior to attending law school at The John Marshall Law School in Chicago. She earned a Juris Doctorate in 2012 and, after passing the bar exam, she was welcomed back to the DuPage County State’s Attorney’s Office as an Assistant State’s Attorney. She spent five years in various units throughout the office, gaining a wide variety of experience and trying hundreds of cases, including domestic matters and juvenile offenses, along with felony offenses, such as burglaries, aggravated batteries and gun cases.

She began her career at the State’s Attorney’s Office handling traffic and misdemeanor cases, including DUIs, domestic batteries and orders of protections. From there, she was promoted to the Felony Juvenile Division where she managed hundreds of juvenile files from intake to disposition. During her time in this division, she also worked closely with DCFS and became well-versed in the various aspects of cases involving abused, neglected, and dependent minors. She continued her advancement into the Felony Trial Division where she handled a range of serious felonies, from felony DUIs and drug crimes, to felony violence charges, with and without weapons involved.

Gabby joined the offices of Mullen & Winthers, P.C. in 2018 as an Associate Attorney focusing primarily in the areas of family and criminal law. Gabby’s extensive courtroom and trial experience as a former felony prosecutor have shaped her into an innovative and zealous advocate who is highly effective at developing case strategies in order to achieve the best possible outcome for her clients. From engaging in plea negotiations to litigating a case at trial, Gabby tackles each and every case with tenacity and an analytical mindset, while keeping the client fully informed every step of the way. Clients can count on Gabby to represent their best interests from start to finish.
