Posted by J | August 09, 2020 | Hired Attorney | Speeding & Traffic Ticket

Speeding/DUI

Jon Katz represented me in a case where I was charged with speeding,, failure to comply and DUI. I felt strongly that I was improperly stopped as I was paced at only a few miles over the speed limit. Jon was straight forward that this was a slim margin chance of victory yet fought hard to prove this ...point. He was masterful in his strategy and more importantly in his cross examination of the officer and challenging the prosecutor. They were no match for his knowledge of the law and his ability to convince the judge it was an improper stop resulting in acquittals on all charges. He is an excellent attorney and all around great guy who even gave me a ride to the airport.

Thank you for taking the time to post your reply. The airport was but a brief detour on the way back to my office, and it was an honor and pleasure during that car ride to savor this acquittal together. Many times I exceed my expectations in court. With the outcome being in the hands of the judge and jury, I endeavor to provide them the information and ideas sufficient to rule in favor of my clients. Thank you again.

Posted by Robert | July 16, 2019 | Hired Attorney | DUI & DWI

Still in shock

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!

Posted by Ryan | June 11, 2019 | Expungement

Great advice from a great attorney

I am an attorney, practicing in the state of Georgia, and called Jon about an issue that a family member was working through in Virginia. Jon not only took the time to explain the legal hurdles associated with post—conviction expungements in Virginia, but he suggested a creative solution to help my f...amily member without asking for anything in return. As a fellow attorney, I eagerly recommend Mr. Katz as a knowledgeable, honest, and thoughtful counselor.

Client

I contacted Jon due to an extreme number of positive reviews online after receiving a Felony possession of Marijuana w/ Intent to Distribute charge. To be very clear, I'm a family man with a career and don't sell Mary J. I knew he cared about beating this case after just 10 minutes of talking to him,... oh and don't interrupt. During the middle of our first meeting I shared that a week prior i got a reckless driving charge and had a pending petty charge from my child's Mother. I presented Jon with 2 misdemeanors and 1 felony. Go Time Listen, focus, execute is what I learned from doing Jon's Homework, do the homework! Jon truly is a master a his craft and his staff is outstanding as well, Lori was terrific. He works extremely hard and dazzles in the courtroom with his knowledge of the law and court system. I must say that Jon truly helped my life in every way possible and I would recommend and have recommended Mr. Katz to anyone who needs an attorney for legal troubles. All 3 charges NOLLE PROSSED, you the man, Jon let's keep in touch !

Relationship: Worked together on matter

"I have been a peer criminal defense lawyer to Jon Katz for a little under a decade. From a distance, I already knew that he was a reputable trial lawyer who is clearly on the more zealous side of the fence than the average practitioner. More recently I had personal collaboration with him regarding a mutual client with serious charges in multiple jurisdictions. Jon worked quickly and effectively to secure unusually-favorable relief for the client, and reconfirmed to me why he has the reputation that he does. I work next door to him and based on when his car is in the lot, I can safely say he is one of the hardest-working attorneys I have ever seen. He is very focused on the latest changes in the law, and he regularly enlists expert witnesses to bring the best and most novel defenses on behalf of his clients. I can safely endorse Jon as one of the most devoted trial lawyers in Northern Virginia."

"Jon is a lawyer’s lawyer. What I mean by that is he is so good at his craft that other lawyers seek to emulate him and come to him for help on novel issues.

He's always up for the fight and willing to do what is right for his clients. As many lawyers would tell you, the ultimate compliment that a lawyer can give you is to either refer someone to you or hire you themselves; that's exactly what I can say about Jon. I wouldn't hesitate to refer should the need arise."

"I worked for Jon Katz for several years prior to becoming a lawyer, and I had the privilege of learning and observing a true legal expert in the criminal defense world. I had the privilege of witnessing an attorney who truly went to war for his clients. Jon works tirelessly for both clients and potential clients, before they even walk through his doors for an initial consultation. From DUI/DWI or drug cases to assault or battery cases, Jon knows the law inside and out, knows how to guide his clients through the criminal defense system from start to finish, and knows how to truly counsel his clients and obtain results. I would refer any of my friends or family to Jon in a heartbeat."

"What can I say about Mr. Katz that hasn't already been said by other attorneys? Not much. So I apologize if I repeat something you have read about Mr. Katz before. Mr. Katz is a tenacious fighter and defender of your civil rights and liberties. Sure he is extremely knowledgeable about the law, but it’s the way he defends others with his level of commitment, enthusiasm and creativity that sets him apart. He is respected by the legal community. He shares ideas and defenses to help other attorneys which is a bigger deal than one might suspect. He will stick his neck out time and time again to voice an unpopular position if he firmly believes in it. Accordingly, he has my utmost respect and endorsement. Chris"
