From a young age, Jessica knew that she had a passion for family law. Jessica finds family law extremely rewarding because she has the ability to counsel and advise clients during the hardest time in their lives. She particularly enjoys being a certified Guardian ad Litem for minor children in DuPage County while helping parents resolve issues of parenting time and allocation of decision-making responsibilities.

Jessica is a graduate of The John Marshall Law School in Chicago, Illinois and is authorized to practice law in the State of Illinois. Throughout law school, Jessica worked as a law clerk at a DuPage County family law firm, concentrating on family law and plaintiff employment law matters. In her last year of law school, Jessica worked as a judicial extern with presiding Judge Pamela Loza in the Cook County Domestic Relations Parentage Division, where she gained extensive knowledge in parentage cases and assisted Judge Loza with preparing her written decisions and assisting pro se parties. During her time in law school, Jessica maintained herself on the Dean’s List. She graduated from the University of Iowa with honors, earning a Bachelor of Arts with a Major in Communication Studies (with a focus on debate) and a double minor in Spanish and Human Rights. During her time at the University of Iowa, Jessica was a co-founder of the Students for Human Rights Group. Jessica was also inducted into the Lambda Pi Eta Honors Society, which was given to students that obtained a 3.6 or higher GPA in their Communication Studies classes. Jessica also worked closely with one of her professors on a gender studies research and writing project that was ultimately published.

Before joining Kollias & Giese, P.C., Jessica worked at a mid-size family law firm in DuPage County where she gained extensive knowledge and experience in the domestic relations area of law. Since graduation from law school, Jessica has concentrated her practice solely in family law matters. Jessica has handled numerous pre-decree, post-decree, parentage, child support, adoption, appeals, relocation, orders of protection, and Guardian ad litem cases, including contested cases involving the modification of parenting time and allocation of decision-making responsibilities.

Jessica is the Treasurer for the DuPage Justinian Society of Lawyers and Vice Chair of the DuPage County Bar Association New Lawyers Division. Jessica is an active member of the DuPage Justinian Society of Lawyers, DuPage County Bar Association, DuPage Association of Women Lawyers, Kane County Bar Association, and the Illinois State Bar Association.

Client Reviews
"Dan's expert handling of my divorce case was beyond my expectations. He takes control, documents your facts and summarizes options for you throughout the process. You will always get a timely response by email or phone. He will not forget the facts in your case or be uprepared for milestones along the way. He will advise on important matters but act per your direction. Finally, he will maintain a positive and professional communication with all parties involved." Jacquelyn
"Lisa has been my lawyer for the past 4 years for various court precedings and has been awesome. She always knew what was going on with my case and always took the time to ask what I wanted the end result to be. She’s tough and not scared to speak her mind in a courtroom in order to fight for her client. Lisa also always worked with me financially in order to work around what I could afford. I would 10/10 recommend her to anyone and would hire her again if needed." Cali
"Ms. Defino did an absolutely amazing job working with me on my case. She was very, very prepared, was excellent in responding to calls, emails and messages, understood the law and worked with with partners of her firm if there were areas that we needed advice and other opinions on. Jessica was a very comfortable to work with, super personal and got all of my needs and wants out of my divorce case. I would highly recommend working with Ms. Defino." Matt
"I was represented better than I could have ever imagined. My needs were put first and was treated as a friend rather than a number. My opinions were valued and my doubts were always reassured. My nerves were calmed and the process was always explained. Jane Nagle fought hard for me. she went above and beyond and did everything she could to ensure a great outcome. I couldn't have asked for a better attorney and her firm. Thank you from the bottom of my heart." Marcia
