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.

Expedient Divorce Lawyer: Punctual, Personable, and Proficient
I recently engaged John Conniff for my divorce, and it was as great an experience as I could have hoped for, from start to finish. He was punctual and efficient, arriving promptly for meetings and court appearances, respecting my time and instilling confidence in his reliability. Communication with Mr. Conniff was great. He explained legal matters clearly and responded to my emails and calls in a timely manner, alleviating much of the stress associated with legal proceedings. His personable nature fostered an atmosphere of trust, making discussions about sensitive matters easier. Mr. Conniff demonstrated proficiency in navigating an amicable divorce. He worked with our mediator to ensure the terms negotiated during the mediation process were captured in the appropriate court documents, ensuring a smooth resolution without unnecessary conflict or fees. Overall, I highly recommend John Conniff for anyone seeking legal representation in a divorce. His punctuality, communication, personable demeanor, and adept handling of divorces make him an excellent choice. I am immensely grateful for his assistance during a challenging time and wouldn't hesitate to seek his services again if needed.

Supportive, knowledgable and fair
From the first conversation John didn't push me into any decision I wasn't ready to make. And when the process took much longer than anticipated he made sure it moved forward while keeping my best interests in mind.

Very happy with quality of service!
John worked with me creating a premarital agreement in February, 2024. We spoke via phone and email a handful of times and I found him to be extremely professional and knowledgeable on the subject. He catered the agreement toward my needs and made sure I (as well as my fiance) understood every single line of the document before signing. Discussing any sort of agreement, especially a premarital one, can be extremely overwhelming, but John made the process painless. I would certainly recommend him for anyone in need of an attorney.

Responsive, Informed, and Strategic: My Positive Experience
After encountering communication and clarity issues with a prior counsel, I turned to online resources and discovered John through client reviews on Avvo. His quick response to my late-night inquiry and immediate scheduling for a consult were surprising, reassuring, and pointed to his dedication early on. John demonstrated a commitment to my case from the very beginning, presenting multiple strategies and walking me through various outcomes. Despite facing a stubborn opposing party, my interactions with John never mirrored this difficulty. He provided clear, strategic advice, ensuring I was well-informed and represented at every turn. His consistent follow-ups and understanding of my financial situation were especially appreciated. And most importantly, his professionalism and empathetic approach led to a resolution that aligned with my personal goals. For anyone navigating the complexities of divorce, John’s expertise make him an outstanding choice.

Best divorce lawyer
I had a great experience with John representing me in my uncontested divorce case. It was dragging for more then a year while we were trying to come to agreement with my husband. I am so happy that John stepped in and insisted on a different version of agreement that protected my interests much better. John is honest, very effective and really looks out for his clients. I am happy with my divorce agreement and would highly recommend John as a divorce attorney. Great job !

Marian Spotts vs Bruce Spotts divorce case
Attorney Conniff, you did an excellent job on my divorce case. I liked how you was able to get order right away with a disorganized plaintiff to get a lawyer for herself. This also helped me get information about the Plaintiff, that I was not able to get on my own. I appreciate your time and hard work that you put into my case.

Breath of Fresh Air
I highly recommend John. I changed my representation to John and I am very happy I did. With John, my stress level and monthly fees decreased and my wins in court increased. His calming demeanor guided the discussions which allowed us to make winning arguments.

Great lawyer
I hired John to represent me throughout the prenup agreement process. In the beginning when I reached out to him he nearly immediately called me back compared to some other attorneys I called that waited days or didn't call me back at all! During our initial conversation, I was immediately impressed by his vast knowledge in the matter and could tell that he truly had my interests at heart. He was organized and on the ball throughout the whole process. His suggested revisions added more flexibility in the agreement and served to further protect my assets in ways that I never would've imagined. While completely necessary, the prenup process wasn't the most pleasant thing to go through but John really helped to put me at ease throughout the process and feel good about the final agreement. I would highly recommend his services to anyone seeking a family law attorney!

Experienced, efficient and extremely helpful
John was a referral to us and I couldn't have asked for a better partner in this process. It's a difficult situation to be in and John was extremely helpful in explaining everything, getting all the documentation together in a way that asked very little of me. I had no idea what to expect going through this, but John made the time to explain everything in detail and see it through to the end. I highly recommend John and his team.

Quick and Efficient
Ending your marriage is never easy, especially with children involved. However, John was able to make a difficult process much smoother through his knowledge of the family court system and compassionate personality. My divorce took less than a year and I am very happy with the terms.

Efficient!! My whole process took two weeks from the date of filing. John was responsive, thorough, clear and handled everything from font to back. He made this process so much easier for me and was amazing to work with in a not so amazing circumstance. Use him now.

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.

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."
