He worked hard to get me a settlement so I could begin my new life

Jon Katz was introduced to me by my cousin’s boyfriend. When I met him for the first time, I was worried about what would happen to my life and future. Jon said keep doing “your homework” to change myself. He worked hard to get me a settlement so I could begin my new life. I was really relieved about it. I remember that when I first went to his office, he showed me that he loves Yoda from Star Wars. After the settlement, I was relieved so I called him “Yoda God”. Me and my family really thank him so much for everything. I am adjusting to my new life and am happy in Florida.

Last year i was charged with a felony drug case. I met with Mr. Katz shortly after while searching for an attorney i felt would put in the work and go to bat for me. I had a couple bad previous experiences with lawyers in the past, but I quickly realized Jon was the lawyer for me. Mr. Katz was direct, knowledgeable, and took charge of the meeting in a way that gave me the feeling he was not easily pushed around in court. My case was put off multiple times, but Jon always kept me in the loop and ALWAYS responded quickly to my emails. In the end Jon was able to get my case dismissed entirely. Our family can’t thank Mr. Katz enough. If you are looking for a lawyer that will truly fight for you, hire this man. while other lawyers are goofing off. Jon is in the books searching for new ways to defend his next client.

He single-handedly helped me out of a situation I didn't think was winnable

If you are here, I was in your shoes not too long ago and looking for a lawyer. I got a DUI and a felony drug charge with a marijuana vape pen in Prince William County, and I was sure my life was ruined, so I started looking at lawyers to try to salvage my situation as best as I could. Mr. Katz came recommended from a friend after looking and talking to 2 other lawyers, thank goodness I made the decision to go with him. He was very prompt in getting back to me (which was the most important thing to me), and we set up a meeting to go over what had happened. I noticed when I visited him that he knew what he was doing and would not bullshit me in any way and would try to get the best possible outcome. We shook hands and he gave me homework. I will emphasize that the homework is THE MOST important thing you can do to help yourself. The court date came and as nervous as I was, Mr. Katz came in very confident and that put me at ease. He consulted with me, then talked to the PA for a good 5-10 minutes but it felt like a lifetime to me, and came back all smiles. I got the best possible outcome for anyone in my position. I figured I would get the DUI so that was expected, but I was really concerned about the felony drug charge because I was originally looking at 1 to 10 years. This madman somehow got it dropped to a disorderly conduct and no probation for anything. To say I was relieved is an understatement, he single-handedly helped me out of a situation I didn’t think was winnable. I would definitely recommend Mr. Katz to anyone because I know for a fact he will work hard to get the best possible outcome for you. Mr. Katz if you are reading this, I cannot thank you enough for what you did for me and I’m definitely grateful for all of your service and I’ll recommend everyone I know to you!
