Nothing but disrespectful people in the entire office, that operate in a completely unecessary and blatantly rude manner.

I came to Jon for help with my domestic violence/restraining order case. My last experience with a family law attorney was a negative one, so I was apprehensive about choosing an attorney to represent me this time around. I decided to go with Jon after reading so many positive reviews, and I’m glad i did. He knew my case was time-sensitive and got me in for a consultation right away. The entire process was smooth and stress-free, and he made me feel comfortable and less scared during one of the most difficult times of my life. You can tell he truly cares about his clients and their situations, and knows exactly what he’s doing when it comes to helping them. I would highly recommend him to anyone needing a family law attorney.read more

It was a pleasure working with Jon and his paralegal, April. I came to Jon after working and speaking with other attorneys in the area. My family law case was complicated and had gotten dragged out. Jon sat down with me and created a clear plan of action along with a timeline. Within nine months Jon brought my complicated divorce and child custody case to a close. I'm very grateful for his work and patience. I would highly recommend Jon to anyone who finds themselves going through a divorce and/or child custody dispute.read more

I fumbled my way through divorce. It cost too much and I felt as if I had no advocate. Found myself facing more issues with a support adjustment and found John here on Yelp. I called and explained my situation and my struggle to find good advice. He provided considerate, timely advice and brought resolution to my issues. I wish I had found him sooner.read more
