Experienced Trusted Advisor - John Fay
I had consulted with several divorce attorneys, and I finally was referred by a friend to John Fay. John Fay explained everything in a way that I understood and in a way that put me at ease. His extreme wealth of knowledge was very valuable and he was a trusted advisor throughout the process. There were some twists and turns throughout the journey, and John Fay navigated through the changes in a calm matter while always pushing things forward. My case seemed like it should be very simple, but it turned out to be unique and at times complicated. John always responded in a timely fashion. It was amazing to see at the end how he and his staff moved at lightning speed to finalize the divorce before the end of the year – truly amazing! The staff is wonderful - friendly, responsive, professional and helpful. I can’t say enough good things about John Fay and the staff. If you are looking for a divorce attorney, I highly recommend John Fay.

Exceptional Representation
I received a referral for Mr. Fay when I found out that I would be going through a divorce...after out first meeting, it was clear to me why he is so highly regarded. Mr. Fay is outstanding! He empathetically guided me through the divorce process. His years of experience allow him to provide me with expert advice; he was extremely knowledgeable with every aspect of the divorce. He was always honest and upfront with me, even when the news may not have been what I wanted to hear. He was available to me anytime that I had a question or concern; he addressed every concern that I ever approached him with. I always felt that he was 100% focused on my case. He has an exemplary professional attitude. He is respectful, calm, punctual, confident, personable, fair, and determined. Without his help and guidance, I would never have received such a successful outcome.

Great attorney and staff!
I was referred to John Fay after I was blindsided by my husband filing for divorce. After my initial consultation with John I knew he was the attorney I wanted representing me. I was an absolute emotional wreck and John had no problem with my brother accompanying me during our appointments - which meant the world to me! Although my trust level was very low, I trusted John and never doubted he would do all he could for me. John was diligent in exceeding my expectations. By no fault of John’s my divorce dragged on for over two years. He never gave up and was persistent in making sure no stone was left unturned. In the end I got much more than expected. John is extremely knowledgeable and professional without being arrogant or condescending. I had many questions along the way and he always took the time and patience to explain. The entire staff was professional, efficient and caring. I would be remiss not to specifically mention Marianne for her knowledge, advise and genuine concern. She was always very prompt and efficient and a great comfort and help to me many times. I would highly recommend John Fay and his staff!

HIGHLY recommend John Fay
I really can't thank John enough for all of his guidance and advocacy during my divorce. He is a first-class attorney and individual who always conducts himself professionally, which was an absolute "must" for me. For anyone who has been through a divorce, you know that it is an emotional rollercoaster, and John helped me through the most difficult event of my life. John understood where my priorities are/were at all times (my children) and helped me reach agreement with my ex that ensures we always put our children first. John also did a terrific job in helping me reach a fair financial resolution. I would highly recommend John to anyone else who needs a smart, professional, and tough but fair attorney to help them get through divorce.

Divorce Experience with John Fay
I met with John Fay as because my husband of 36 years requested a divorce. Need less to say, I was shocked. In spite of my emotions, I needed to obtain legal counsel. Divorce is complicated. John and his staff were very patient and supportive throughout the whole process. My divorce was challenging and there were many roadblocks thrown at me by opposing counsel. Although it is very expemnsive, John did his best to keep costs down. I was surprised because I had heard from many friends that attorney's do whatever they can to get money. This was absolutely not the case with John. Near the end of my divorce, a lot of negotiating occurred. John was very responsive to my concerns, questions, and anxiety. I highly recommend John Fay but hope that you never have to go through a divorce. The whole process is brutal!
