The Best!
John is an amazing attorney with an outstanding team. After using several attorneys in the past for a complicated, messy situation that seemed to never end John got the job done and got it done quickly. I was hesitant to hire another lawyer after John was referred to me in fear of being over charged and getting nothing accomplished. This was not the case with John. He was compassionate, understanding and didn't miss a single detail, which in the long run will make your life easier. I'm so grateful to have worked with John and cant recommend him enough - you want this man on your team asap if you're going thru a divorce, custody or support issue.

My attorney
John is a great advocate for his clients. He is straightforward and totally honest and, most importantly, he does was he says he will do when he says he will do it. I was very impressed with his professionalism and knowledge.

Best in Class
John Conniff is exceptional.  He secured a far better judgement and outcome than I originally hoped for; because he KNEW that the onslaught of attacks & petitions against me were anything but fair.  He is thorough, responsive, and insightful. Above all, he truly listens, providing understanding and clarification to all of the nuances and intricacies of my case.  He's not just "going through the motions" like I've seen with many lawyers.  Truly, he is on your side and in YOUR corner, every step of the way.

Great Experience - Premarital Agreement

John is an excellent lawyer. He represented me in a difficult custody case. I live on the east coast and John was able to work with me to gain custody of my son.

Thoughtful, Understanding Attorney
John came to me highly recommended and he did not disappoint in my dealings with him. As someone who was going through a really tenuous situation, he really took his time explain to me all of my options and in such a way that I felt both supported and empowered all at the same time. John explained all processes thoroughly and gave me his expert legal advice for every scenario that came about while also giving me other options, which I very much appreciated. John’s timeliness, thoughtfulness and attentiveness really made this highly charged emotional situation bearable. I would recommend John a thousand times over!

Divorce is overwhelming process that takes emotional toll on anyone. Finding the best attorney representing you is essential and John is just that. John took time to answer all my questions and concerns and walked me through the process in detail. He was very thorough and kept me well informed throughout the divorce. John always returned phone calls and emails promptly. His guidance and advice truly are the reasons behind getting through this difficult situation and I would highly recommend his services to anyone.

Child Support
Filing for child support for my son is nothing I would ever imagine I would one day have had to do. It is very hard to explain in depth your situation to a stranger, holding emotions back on such a sensitive subject, let alone sharing personal documents supporting your case. John was extremely helpful in my case and was always available when I had questions or concerns. He treated my case like it was top priority. I would highly recommend his services.

Divorce and separation Attorney | 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."
