An absolutely amazing human being and team. They are knowledgeable and caring, especially during some of the most emotionally difficult times in one’s life. I could not recommend Eric and Kim more.

Eric recently represented me through a long and very challenging matter, including the involvement of several third party professionals/experts. He is a superb strategist and provides excellent guidance both legally and personally. He always takes the high road and seeks to avoid conflict and manage costs. He is highly respected by his peers, the courts, and other professionals who support the family law community. In summary, if you're looking for someone to expertly guide you through an often challenging and unpleasant process, Eric should be your first call.

At an incredibly challenging time in life, it felt amazing to have a great lawyer and his team in my corner. Every time I mentioned to someone else in the divorce industry that Eric was my lawyer, they commented on how lucky I was. I always agreed. He has a great reputation as a very talented and trustworthy lawyer, which he upheld every step of the way. He is not inexpensive and I thought his counsel, and compassionate approach, was worth every single cent.

I hired Eric after two previous lawyers with whom I was not satisfied with. He took my matter of trying to retain my former husbands tax returns seriously. He not only managed to get them, he negotiated what was due to me from past years and alerted me on the low child support I had been receiving. He is an outstanding litigator, very organized, trustworthy, and extremely knowledgeable lawyer. A rare find in Greenwich, CT. He was always available when I needed to chat, mostly I trusted him. I could rest easy knowing my daughter and my future were in his hands. I would recommend Eric to my family and friends.

Eric is an outstanding attorney. He was referred to me by a friend and I would strongly recommend him to anyone going through a divorce. You definitely want him on your side. He is an expert negotiator who has keen attention to detail but appropriately balances that with the big picture. He guided me through the entire process in a highly effective manner. He operates with compassion and provides a realistic assessment of where you stand. He was responsive and both he and his team were quick to answer questions/calls and turn things around. He did a great job of setting my expectations throughout and delivering a good outcome that I was very happy with. If you are looking for a divorce attorney, you need look no further.

Eric is an excelent attorney. I describe him as an invaluable life saver amongst a sea of sharks. He has a bias to resolve matters in a non-adversarial manner, but will represent his clients with strength, professionalism and attention to detail as necessary. I appreciated his counsel, candor and assurance in my divorce process. I was much better off for having had him in my corner. I would highly recommend him to anyone who needs wise counsel through the divorce process.

Eric was a great ally to have in my corner through the toughest time in my life. He is highly knowledgeable, highly experienced, compassionate, and tough. His office staff is top notch as well. They return calls immediately and prepare documents in the same fashion. I couldn't have made a better choice of attorney. I do not hesitate to recommend him.
