Jon Katz is a battle-tested three-decade criminal defense/ DWI defense lawyer who goes to court with trial-ready strength and preparedness. Jon thrives on pursuing the best possible results in court for each of his clients. 

Criminal defense is war, requiring being armed to the teeth, and progressing the proverbial fighting as needed from checking before hurting, hurting before maiming, and maiming before destroying. Criminal defense is also about lessons from martial arts, using fearless cunning and strategy over brute force, and drawing from my daily martial arts practice. The stakes are often high, and the battle should be treated as a one-chance-only affair.

Jon defends in Northern Virginia and beyond, including Fairfax County, Arlington, Alexandria, Prince William and Loudoun Counties. He spends virtually his entire time defending criminal defense and DUI clients, fighting for the best possible results for his clients, and repeatedly going to trial when needed. He has successfully defended over 3000 clients in criminal court since 1991, and has taken hundreds of cases to trial. Many of Jon's trial highlights are at .  

My staff and I will be delighted to arrange a free consultation time for you to meet with me if you seek a criminal defense or DWI lawyer.

Review for Jon
Jon was an amazing lawyer. He really knows what he's doing when it comes to law. I recommend Jon, he will fight for you. It was my first time going to court and was nervous but Jon made me feel comfortable.

Knowledgeable. Experienced. Relentless.
If Jon Katz is your defense lawyer, you will get all three of these characteristics fighting on your behalf. He knows the law, so he will provide you expert advice and collaboratively develop your most effective defense strategy. Over 3 decades of experience, Jon will use his trial, negotiation, and relationship skills to produce the best results for you. Facing multiple charges ranging from a 2nd DWI/DUI within 5 years, as well as several other misdemeanors, Jon was able to aggressively negotiate and get the DWI/DUI case reduced to reckless driving with the other misdemeanors either dismissed or mitigated favorably. Hiring Jon was one of the best decisions I could have made both personally and professionally. Highly recommend Jon for your Defense Attorney.

Response from Jonathan Katz February 26, 2023
My clients' satisfaction is key. I am delighted that we avoided a conviction that would have gotten you mandatory minimum jail time (if convicted of a second DWI within five years) and that we were able to reduce DWI to reckless. Thank you for posting your review. Jon Katz

Impossible DWI case
Jon has represented me for my 2nd DWI charge with accident and BAC over 0.20, which seemed impossible to get out of. The case was reduced to a reckless driving. From consultation to case closure, Jon was detailed in every step of the way, and made sure I was aware of every single possible outcome. He will go all out for you, you just have to trust his work and do what he asks. I mentally prepared for the worst case scenario because my case seemed unsolvable. As I am writing this, I still can't believe how Jon was able to attain this result. I will forever be grateful for Jon and his team for literally giving me a new life. Thank you, Jon, from the bottom of my heart.

Savior sent from God.
Mr. Jon Katz replaced my previous lawyer who was not providing proper services. The moment we signed the contract, unlike my previous lawyer he started to gather every small details about my 5 Cases (4 felonies and 1 misdemeanor) and even before requesting for a discovery he started preparing a defense strategy. He finally got me a ‘nolle prose-cue’ decision by the common wealth for all those cases. Although, I was innocent in the first place, Mr. Katz was like a savior sent from god to legally help me get a result that I deserved. I am a religious person so the way I would phrase my message to people looking for a Fairfax criminal lawyer is that ‘ Trust God first and Jon Katz after, for any criminal case that God forbidden you might face’.

Great Lawyer
Jon was introduced to us by a family friend, he is one of the top Criminal Defense lawyers in Fairfax, Virginia. From our first meeting with him, we could tell he was an expert in his field and during a challenging time he provided us with guidance and a comforting environment to work on my son's case. When we had questions or needed his assistance Jon was always a phone call away. He worked diligently to support us through the complex process of defending our case and was able to secure a settlement for my son. I couldn't have asked for better representation while we navigated a challenging time for our family with the added hardship of the initial Covid-19 lockdown. He fought to move our case along when resources were limited. I am grateful for the honesty and integrity he maintained throughout our conversations. You can count on him to take on difficult criminal cases and provide a winning solution. Our family will be forever thankful for his help.

Jon came through as always
Jon represented me for an assualt charge during COVID. The case was reduced to disorderly conduct do to his excellent maneuvering during trial. I very highly recommend Jon for an attorney.
Response from Jonathan Katz January 19, 2023
An acquittal or dismissal is great, but a disorderly conduct disposition looks better than an assault conviction. I am pleased that you are satisfied with what we achieved in court. Jon Katz

Dismissal of a complex case
Mr. Jon Katz demonstrated the breadth of his legal expertise and knowledge when I hired him to represent me in a particularly complex case. He explained the legal process in a manner easily understood by a layperson but was not at all condescending. Mr. Katz also adequately prepared me for my deposition to prevent me from becoming flustered in a setting where opposing counsel posed seemingly confrontational questions at a rapid-fire pace. He was also adept in questioning the opposing witnesses to where the judge dismissed the case. Mr. Katz was also very helpful in expunging my case. With his impeccable credentials, I highly recommend Mr. Katz if you seek legal representation.

Excellent Criminal Defense Attorney
Excellent criminal defense attorney in Fairfax. Jon represented me on 3 very unfair misdemeanor charges the County was insistent on pursuing, including assault. In court Jon was able to get 2 of the charges dropped and a not guilty verdict on the assault charge without even having to put me on the stand (which helps for any potential parallel civil matters). His staff was a pleasure to work with and incredibly professional and responsive. Jon's direct style and approach is efficient and I was very thankful for it when I received a refund at the end that I wasn't expecting! Very glad that I chose him.

Always being trial-ready means not relying on settling the case, but having trial-readiness empower settlement negotiations. Thank you for the opportunity to have achieved this great trial victory with you.

"Jon is an exceptionally skilled attorney with extensive understanding of the law. I have watched him in action on numerous occasions, winning trials for criminal offenses and DWI offenses for his clients.

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."
