Katz is A+

Mr. Katz is a great attorney. I hired him after searching for someone that I thought was going to help me out the best way possible. Mr. Katz got my case dropped from a reckless driving to an illegal use of equipment. Which was a blessing. Mr. Katz is gold. Every step of the way he explains everythin...g very well and makes sure you understand every inch of the process. Mr. Katz has a passion for what he does and you can tell that; most attorneys are not as passionable as he is.

Thanks for commenting. My passion and thrill for defending people accused of crimes burns as strongly as when I started practicing criminal defense over 25 years ago. All the best to you.

Methodical and Tenacious ( DUI - NOT GUILTY)

First off - Jon is a very affable person who makes you feel at ease when explaining your situation. He is non-judgmental, does not look down you or the situation and warms up to you pretty quick thereby putting you at ease and allowing you to give him very critical and important information crucial t...o handling the case. I have been arrested twice for DUI within a span of 1 year and things for not looking good at all - I was depressed, stressed and extremely worried. Jon came highly recommended and I reached out and he worked his schedule around to meet with me the same day after office hours. I explained my situation to him - and after patiently listening to me for a half hour it to me right on my face (2nd arrest in short span) would trigger jail time in addition to ASAP, restricted license and probation). He gave me homework and said he will only be able to his best if I am diligent with the homework. Jon is well read, knows the law and most importantly knows how the Fairfax County court works as he is there every single day. He knows the Judges and Prosecutors - and clearly explains his strategy clearly before each court date. (Yes, he would ask for continuances so that you do enough homework to strengthen your case). I had very little hope, given how I screwed up and even registered for ASAP voluntarily based on Jon's suggestion. I did all he asked in with diligence and just trusted Jon to be my savior. On the trail date - he can very prepared and relentlessly pursued the prosecution to offer plea, and in those discussions found out multiple flaws in the case and also quickly assessed the weaknesses in case. He said he that we should stop asking for a plea - and go to trial. His demeanor, confidence and erudite assessment of the situation and hand was so convincing and impressive that I said I will just follow his orders. The trial lasted for over an hour and Jon was relentlessly pounding the officer, prosecutor and changing the thinking of the judge with every new argument exposing several weaknesses in the case. What was hopeless slowly started t0 look better due the methodical and tenacious behavior of Jon. Result: NOT GUILTY. Hands down – the best choice I have made based on my overall experience, I would STRONGLY RECOMMEND HIM. DO whatever he says and give him the ammunition to fight for you. He can make things happen. Have belief and respect his homework, decisions and most importantly his gut feeling on how to proceed.

Best Criminal Defense Lawyer in Town -A true master He is

As many of you are doing right now, constantly looking through reviews on Avvo, Yelp, Google to find the best lawyer for whatever "mistake" you have made, I was in the same situation with DWI as well as serious felony charges that could have jeopardized my permanent residency even if the charges were... lowered to a lesser "misdemeanor". I had about 4 different free consultations with 4 different lawyers. Mr. Katz was the only lawyer that actually listened to my story and cared for me as a person, not just another client with a dollar sign. He is not that type of lawyer that gives false hope to comfort but rather he gives his genuine opinion and advice, coming from years of experiences. Long story short, felony charges were dropped completely! My outcome was much better than I dreamed of and I am so grateful that I found Mr. Katz to represent me for the case. Thanks to Mr. Katz, my permanent residency would not be affected AT ALL. As many of the reviewers have said, PLEASE LISTEN to what Mr.Katz suggests to you and DO all the "HOMEWORKS" he gives you. If you have any questions regarding your "homework" or anything related to your case, JUST ASK Mr. Katz and he will always be prompt and honest when providing the best advice for you. In the end, it will help your outcome of the case! For anyone looking for the best criminal defense lawyer in town, look no further and just hire him and do the homework!

Thanks for taking the time to write and addressing the benefit of defendants taking proactive steps in pursuing a favorable outcome in their cases. I am happy that you are pleased with our case outcome, and that your permanent residence status is in good shape. All the best to you. Jon

Posted by anonymous | March 13, 2018 | Hired Attorney | Expungement

Marijuana Case

I was looking for a lawyer who won't just show up to court and have me interviewed for the 251 program. That is not something I wanted to do since the 251 program won't allow you to expunge the possession of marijuana case. Found Jon Katz through a friend who told me he's the best in the business. Pr...ice is a little hefty, but worth every penny. You want the best chance of winning your case? 1. Do the homework he gives you. 2. Let him do his job. The man is unparalleled in his field. He's also has a great sense of humor and can teach you a lesson or two about life. Hire him!

Jonathan Katz

Replied last March 13, 2018

Thanks for your kind words. You honored me by giving me the opportunity to beat the 251 option. Marijuana needs to be legalized throughout the land. Until then, each pot prosecution must be fully defended.

A lawyer who believes in what he is doing

If you are charged with a crime in Virginia, you want a lawyer who understands the plight of the criminal defendant, and who believes that he is fighting on the side of justice. This devotion to criminal defense drives Jon to work as hard as I have ever seen anyone work. He truly loves his job, and t...his is especially evident in the courtroom, where his high energy and confidence have him stand out from other attorneys. I was charged with felony marijuana distribution in Virginia, which caused a great deal of anxiety. After talking to several lawyers I knew Jon would best serve my interests. We began discussing my arresting incident, and since he has been defending marijuana cases for over 25 years, I learned that there were several defenses we had (none of which involved snitching). Up until my trial date, we had several conversations about my case and went over all of the evidence as thoroughly as possible, as well as documented homework assignments to help with negotiations. Jon had my case fully prepared for trial, which eventually led to a plea deal with the conditions that I was hoping for. Throughout the whole process we shared funny stories which helped put me at ease, and totally shattered my preconceived notions about lawyers. Not only did Jon get me the result I wanted, he also made sure that the probation office treated me fairly and gave me as much freedom as possible. If you are charged with a crime, you do not want a lawyer who used to be a prosecutor, you want a lawyer who has spent his entire career battling prosecutors with a sense of purpose.

Thanks for your feedback. The teamwork between me and my clients is so very important. Along the way, I very much enjoy the human interaction with the people I defend. All the best to you as you proceed forward. Jon

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."

He's always up for the fight and willing to do what is right for his clients.

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."

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"
