Quick, efficient, AMAZING service!!

Attorney John Conniff provided excellent, top notch service as my divorce lawyer! I had been putting off hiring a lawyer for almost 5 years thinking I could do not without an attorney, but I hired him instead and he was so efficient, caring, and on top of things! He keeps his clients best interest 10...0% top priority. I can’t say enough good things! I highly recommend him!

Highly Recommended

I am extremely grateful to have had the pleasure of working with John Conniff. He has shown great attention to detail in helping me with working through my legal situation professionally and personally. I wish John practiced law in other areas so that I could have him represent me in business as we...ll through the various needs of business law most business owners face. John possesses compassion and understanding in how complex these situations are for families and parents. Sometimes things do not work out within relationships but on the other side of it, sometimes they do! John has shown great attention to the needs of the family as well as the client/attorney relationship. I would highly recommend John Conniff as counsel to those in need for this delicate practice of law. John is a very intelligent and classful person. His understanding of his specific study of law is top notch. Thank you John for all that you have done to aid in helping to take care of myself and my family. I wouldn't recommend anyone else to those in need of your services but you! Best of luck in your career John! Hope I can provide such professionalism to another as you have done for me!

Responsive and caring lawyer

Mr. John Coniff is an amazing lawyer who was there for me when I was going through my divorce. He was always available by email, text, or phone and I knew I could rely on him throughout the divorce process. His expertise on all the divorce process information was thorough and concise. I would definit...ely recommend John as an excellent lawyer.

The BEST divorce attorney period

I thought I was going through an amicable divorce until my ex-wife and her lawyers went crazy on me from every direction, I had hired John after looking at his reviews and record. To say that he took care of everything from a legal standpoint, gave me direction and made me feel at ease through the en...tire process is an understatement. I'm so glad I hired him to get me through this terrible divorce, if I was able to give him 10 stars I would...

Professional and Staright forward

John Conniff was one of three lawyers that I wanted to consult with to discuss my case. While I had to go through assistants to schedule an appointment with the other lawyers I was able to talk to John directly on the first call. He was a thorough professional in our initial meeting and was very stra...ight forward. It was due to his professionalism and straight forwardness I decided to hire him as my attorney. Whatever the situation of your case John will let you know what the best way forward is. During uncertain times you have questions and concerns and I was glad that John was always available via email, text or phone. He is very prompt in his responses via email and whenever I called his office or his cell phone I always got a hold of him or he returned my call within hours. His fees and rates are very reasonable for an attorney of his quality. He understands that going through a child support case can drain finances and he’s willing to work with you on his bill. His high reviews are well deserved and well earned.

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."
