Whether a matter is simple or complex, contested or uncontested, we serve clients in DuPage County, Cook County, Kane County, Will County, and surrounding areas. We also represent clients in matters of business planning, estate planning, and bankruptcy.

Dedicated to practicing law with a common-sense, problem-solving approach, we focus first and foremost on understanding each client’s particular needs. We provide each client with a thorough explanation of his or her legal rights and obligations, so that he or she can make fully informed decisions. Recognizing that each client and each case involves a unique set of circumstances, we then design a personalized strategy that responds to the facts of each case.

Skilled Negotiators & Experienced Litigators

At Kollias & Giese, P.C., client satisfaction is our highest priority. Our DuPage County divorce attorneys understand that from a client’s perspective, the best strategy is often the one that brings about a swift and amicable resolution to a legal dispute. At Kollias & Giese, P.C., we know that for most people, the legal process can be an extraordinarily unpleasant experience. Litigation is expensive, time consuming, and aggravating. Moreover, litigation often involves a great deal of uncertainty, as it is ultimately up to a judge to decide who will prevail. At Kollias & Giese, P.C., we make it a priority to explore whether a favorable outcome can be achieved for our clients without the need for unnecessary litigation. Our attorneys are skilled negotiators, so that when the opportunity for amicable settlement presents itself, we endeavor to achieve the best possible results for our clients.

We also recognize that successful negotiation requires two willing participants, and that it is often the case that an opposing party adopts an illogical, unreasonable, or legally untenable position. In such cases, a client is faced with a choice to either to litigate or accede the other side’s demands. When litigation is the only rational choice available, we stand up and fight for our clients. At Kollias & Giese, P.C., we are experienced litigators who offer tough, aggressive representation while remaining mindful of the fact that persuasion is an art. We place great emphasis on being prepared and well-organized, so that when we go to trial, our attorneys have full command of the facts and the law, and present them to the court in a clear, concise, and persuasive manner.


At Kollias & Giese, P.C., we believe that effectively representing our clients’ best interests requires us to keep our clients well-informed about their cases. Not only do we take the time to explain what happens at each step of the legal process, we also make it a point to respond to all phone calls, emails, and other written communication within a reasonable amount of time. We copy our clients on correspondence with the opposing attorney and the court. Furthermore, we always afford our clients the opportunity to review all pleadings and discovery documents. By doing so, we ensure that when it comes time for a client to decide to settle or litigate a case, he or she has access to all of the information necessary to make the right decision.

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
