Hire this guy!

I contacted John on a Monday morning and asked if he would quickly help with a Premarital Agreement- all to be completed in 2 days. He jumped right on, happy to help but cautious that it was under the right pretenses. I felt like he had my best interests from beginning to end, was professional, timel...y, responsible, and personable. He is easy to talk to and makes you a priority. I would absolutely recommend him and wouldn’t hesitate to call him if I ever needed counsel again.

A Grateful Client

Simply put, John is a wonderful person and an excellent attorney. Hiring him was literally one of the most important decisions I've made in my life that also turned out to be one of the best decisions I've made in my life. Divorce is obviously a difficult process to go through, and adding children to... the mix makes it even more difficult. John was with me every step of the way offering his guidance and support, and always having not only my best interests at heart, but my children's as well. He also did a tremendous job of explaining what was happening throughout the process, why it was happening, and offering his advice when I needed it. During my divorce, I even recommended his services to a friend of mine and wouldn't hesitate to do so again. I can't recommend John enough. Now that my divorce is finalized, I am happy to call him a friend.

Divorce and Family Law

John's work and expertise were instrumental in reaching an acceptable agreement with my now ex-husband. At first, I consulted with several law firms, but what drew me to John Conniff was that he offered objective and reasonable recommendations. He also provided me with clear working expectations whi...ch were consistently met. The transparency in John's work also enabled trust and gave me the reassurance that I needed to stay confident during this difficult process. John's professionalism is very well received in the courtroom and he is a pleasure to work with too. Mr. Conniff genuinely demonstrated concern for my daughter's safety and well-being. Whenever he suggested potential solutions to any rising conflicts that transpired, he'd offer comments like this is not in your daughter's best interest and or this is not acceptable parenting behavior. John's prompt actions were quite effective too. For example, when I found myself in an unsafe situation, John's quick response enabled my ability to be granted a no-contact order. He also assisted in securing a safe location to drop-off and pick-up my daughter so that she could continue her visits with her dad. These prompt actions also helped establish firm ground rules and expectations with my ex-husband. I highly recommend John Conniff because he is truly an expert in his field.

Great Lawyer During Difficult Times

John was my divorce lawyer and represented me extremely well. John was very good at being level headed and helped me stay as level headed as I could when negotiating sensitive issues. We were able work together long distance and I had complete trust that he had my best interest at hand. He made su...re I was able to get as much time as possible with my kids. I know that he worked hard on my behalf and was great at communicating and keeping me up to date on a regular basis as to where things stand. He listened well to my line of thinking and served me well and would also challenge me when he didn't believe a position was in my best interest long term. John was also able to negotiate down considerable debt that I was carrying as well and I am grateful he was able to do that. John was a true professional throughout the process and was also a human being who understood this was a difficult process and would remind me that things would get better in time. He was also good at breaking things down and explaining concepts in laymen's terms. Whether you are in Chicago or another state and need an Illinois divorce lawyer, I highly recommend John. You can trust he will work hard and represent you well.

Divorce and separation lawyer | Jul 02

Relationship: Opposing Counsel on matter

"John and I were opposing counsel in a divorce that dealt with some highly sensitive issues. Our clients approached the divorce in a civil manner. However the divorce dealt with some highly delicate issues that, with a lesser lawyer, could have turned into a fought out divorce. Together, we managed to negotiate the issues and provide our clients with the civilized divorce they deserved. I credit John for keeping matters calm and steering the case away from litigation and moving it toward settlement."
