Thank you!!
I hired John the very day that I decided to file for my divorce. He was the very first attorney that I spoke with, and after speaking to him for just moments I knew that he was a good fit for what I was looking for. Through my two plus years of this process, John has been understanding of my needs, highly responsive, educational, empathetic, and a great listening ear for me. John was always well prepared for our court dates and also for the day of my trial. I appreciate John more than he will understand. I feel that he had myself but also my child’s needs and wellbeing at heart. He fought hard and with his assistance and representation I was able to get just about every single thing that I asked for during my divorce; most importantly sole custody of my child. John, from the bottom of my heart THANK YOU for everything!

Fair, Effective, Efficient and Compassionate
I hired John midway through my divorce because I was not pleased with my first lawyer. John was able to get up to speed quickly and jump in,right in the middle of negotiations. The dynamics in each divorce are different and John took the time to listen to my situation and focused on my needs. He helped me understand what to expect if the court were to decide our case vs. us coming to an agreement which helped me as I was asked to make decisions. He negotiated with the opposing council and was able to bring our divorce to a resolution much quicker than I anticipated. When the stress of the divorce was at its highest, John showed compassion but also re-focused my energy to the legal aspects needed to finalize the divorce. At the last minute when it looked like our deal was about to fall apart, John again worked effectively with opposing council to get over the last hurdle and move the case to resolution. I also felt that John was very respectful of my money. He worked hard and efficiently to quickly resolve the case and keep my costs to a minimum.
