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 sing...

"John is truly amazing at what he does. I wouldn't hesitate to send my clients his way."
"John is well respected by the Judges and other lawyers in his community. He is very reasonable to work with and gets the job done. He tries to promote settlement when possible, to avoid the expenditure of unnecessary fees on a matter. He is also very skilled if the case needs to be taken to litigation. I highly endorse him."
"Great attorney, very knowledgeable and responsive to his clients. I endorse this lawyer!"
"I have had the opportunity to know John for more than 10 years. Not only is John extremely knowledgeable, but he is someone who will fight tirelessly for his clients. I strongly endorse this lawyer."

"Mr. Conniff is a very knowledgeable and experienced attorney. I endorse this lawyer."

"I have worked with John on a number of family law issues over the years. Each time I am impressed by his professionalism, knowledge, and ability to advocate for his clients both in and out of the courtroom. I would strongly recommend John to anyone looking for a family law attorney."
"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."
