About me

Greg has devoted his entire professional career to helping clients involved in complex divorces move their cases efficiently toward resolution and achieve the best possible outcomes. He works on all aspects of family law, but concentrates on complicated high-net-worth financial matters for C-suite executives, business owners, and their spouses. He is equally skilled in resolving complex custody and visitation matters.

Recognized as an Illinois Super Lawyer Rising Star, Greg is sensitive to the turmoil and confusion that accompany the divorce process. He puts his clients at ease by assuring they have a clear understanding of what to expect as the process unfolds and by educating them on what the law provides. Aligning expectations with case realities also leads to greater comfort and clarity.

From the beginning to the end of the process, Greg skillfully guides—and stands by—his clients. He helps clarify goals and develops the most appropriate plan and strategy to achieve them. Highly communicative and responsive, Greg keeps clients well-informed, and keeps his promises. He clearly explains the upside and downside of decisions that must be made along the way, as well as the potential outcomes available.

With in-depth knowledge of the law and superb strategic, negotiation, mediation, and trial/litigation skills, Greg tailors his approach to the needs and circumstances of each client, pursuing a cooperative, negotiated settlement when appropriate and viable. When settlement is not viable, he is always prepared and ready for trial. As a trial lawyer, Greg has a reputation for integrity and for being creative, tenacious, and willing to stand up for his clients to protect and secure their futures.

His prowess in high-stakes financial matters includes division of assets, including stock options; income determinations; interpretation of employment agreements and benefits; and the allocation and division of qualified and non-qualified benefits.

Regardless of whether resolution is obtained through negotiation or litigation, Greg’s broad objective is always the same: to provide exceptional service and value to his clients and assure their satisfaction.

Greg is currently the President for the Kane County Bar Association, which honored him with its Outstanding New Lawyer award in 2008. He spent a number of years serving on the Board of Managers for the Association. He has also served on the Assembly for the Illinois State Bar Association, which is the Supreme policy-making body of that organization.

Greg frequently lectures and publishes articles on financial aspects of divorce and family law for the Illinois State Bar, Kane County Bar, and the DuPage County Bar associations, among others.

He earned his Bachelor of Science degree from Bradley University, where he majored in business administration and management, with a concentration on legal studies in business, and minored in economics. He earned his Juris Doctor from the John Marshall Law School, where he was a member of the Corporation Law Association.

He also obtained advanced training in matrimonial law litigation at the American Bar Association’s Family Law Trial Advocacy Institute held at the University of Denver Sturm College of Law. In addition, he has received mediation training from nationally recognized mediators, authors and educators.
