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.

Fires on all cylinders
Jon was able to secure an amazing, seemingly improbable result for my DUI case with an accident, especially considering my imperfect record. He is able to bring considerable knowledge and experience to bear inside and outside of the courtroom. Like racecar drivers who use every inch of the track to maximize their velocity, Jon left no advantage unrealized when preparing for trial and frankly gave the prosecution little room to maneuver. He surpassed all my expectations and I would recommend Jon to anyone stuck in a jam with the law.

Response from Jonathan Katz July 23, 2023
As my great teacher SunWolf told me early in my criminal defense career: "Reality is no obstacle." That of course does not mean to be able to expect to walk through a brick wall, but to find a way to work around the wall or to dismantle it. That level of positivity helps me achieve amazing results in court. Thank you for the opportunity to have defended you . Jon Katz

Thank You, Jon!
I couldn't have asked for a more comfortable and reassuring experience with Jon. He walked me through every possible scenario regarding my case and helped work me through all of my options. Rachel and Christiana were also fantastic, keeping me up to date via email as well as providing quick responses with my questions. Jon kept me at ease through the whole process with his sense of humor (definitely a high mark there!) and his continued assistance.

Great Lawyer!
Jon Katz is the best in business! He was able to reduce 2 serious cases into one but not only that. Instead of being a misdemeanor, he used his experience and knowledge to make it a traffic infraction only. Thank you Jon!
Response from Jonathan Katz June 3, 2023
As one of my early trial teachers showed- Reality is no obstacle. What a great result we obtained. The rush I felt when we achieved this outcome was incredible. Thank you for the opportunity to defend you. Jon

Most of my criminal defense and DWI clients have little to no experience in court, which at once is a land of opportunity and landmines. Thank you for the opportunity to have obtained a great outcome for you in court.

Mr. Katz Truly Saved My Life
As you read this message, you're likely experiencing the same worry and dread about the future that consumed me a few months ago. The realization that my own foolish actions could result in losing everything I had was devastating. Looking back on that period, the best decision I made was to engage Mr. Katz as my attorney. I searched frantically for legal representation, contacting no less than ten lawyers, only to sink deeper into despair. Their words echoed in my mind, "OMG, These are the most charges I've ever seen," "You're almost certain to face jail time," "You'll undoubtedly have a criminal record." Despair became my constant companion, enveloping my life in complete darkness. But when I met Mr. Katz, my instincts told me he was the right person. He has a lot of experience and knows the law ins and outs. He knows what to do to get the best outcome. Having delved into the depths of Mr. Katz's blog posts, I was astounded by his extraordinary expertise and unwavering passion for his profession. He is a genius, even when you are in absolute darkness, he can always find you and bring you light. Mr. Katz and his dedicated staff Rachel, kept me well-informed about the progress of my case. His door was always open to me. Every time I meet with Mr. Katz, I feel more relaxed than ever. On the day of the trial, when I saw Mr. Katz's confident smile, all my tension dissolved. Court was his home turf, and he was a fearless warrior. I could hardly believe my ears when Mr. Katz told me the final outcome: ALL CHARGES WERE DISMISSED! Leaving me with a clean record and no loss! This result I never dared to expect, but Mr. Katz did it! I have no doubt that you will experience the same immense gratitude that I feel for making the correct decision—having Mr. Katz to stand by your side, fighting tooth and nail for you. No amount of thanks can adequately express my gratitude to Mr. Katz, who truly saved my life.

Exceptional Legal Expertise and Compassionate Guidance
I'm absolutely grateful for Mr. Katz's exceptional legal expertise. We were extremely lucky that Mr. Katz is not only a Fairfax criminal lawyer, but also extremely experienced in Loudoun County where the system is nuanced and rigid, even for first-time offenders. He worked diligently since day one to build the strongest case, understand every facet of the situation, and guide us through every step of the process. Whether it was organizing an expert witness, like Mr. McGarry, or court reporters, etc. he made sure that our defense strategy was comprehensive and detailed. It's only because of his expertise and preparation that the sentence was reduced by the prosecution to reckless driving and agreed to by the judge. Even post case, he's been in touch consistently to make sure that any next steps are taken care of and any questions I have are answered. What I truly appreciated throughout the process was the clear and straightforward way Mr. Katz explained things to me as a client. He ensured I was aware of every possible outcome, the implications in different scenarios, and what we needed to do next. His in-depth knowledge about DWI laws and compassionate approach towards his clients makes him truly an amazing lawyer. His team, especially Rachel Kern, was extremely helpful in coordinating all the details of my case and keeping us up to speed. Their proficiency, integrity, and commitment are unparalleled. If you're in need of legal assistance, I highly recommend Mr. Katz and can't thank him enough for helping us through this difficult situation.

Criminal defense Attorney | Oct 19
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."
Criminal defense Attorney | Nov 29
Relationship: Fellow lawyer in community
"Mr. Katz is one of the most knowledgeable practitioners I know. I was fortunate enough to meet him when I was a young attorney in Northern Virginia. Now that I am a practitioner in the Richmond area, I refer him all my NOVA criminal matters since I know every client will be treated with dignity and will get the best representation. I highly recommend Mr. Katz."

When I need to refer someone to a criminal defense attorney in Virginia, Jon is always my first choice."
Criminal defense Attorney | Feb 28
Relationship: Fellow lawyer in community
"John has taken care of many of our clients. We always know they are in great hands. He is personable, well-respected in the community, and always gets the results that many think are sometimes impossible. I would recommend Ms. Katz for anyone looking for a great criminal defense or DUI attorney in the Virginia area."
DUI and DWI Attorney | Nov 12
Relationship: Fellow lawyer in community
"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. Whereas most lawyers would not openly share information, Jon is always eager to help because he is a master of his craft. He is my go-to in Northern Virginia whenever I have a friend or client in need."
DUI and DWI Attorney | Nov 11
Relationship: Fellow lawyer in community
"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. He is always polite and cordial with colleagues, and gracious and understanding with his clients, but a bull dog in the court room. I full endorse Jon and his knowledge and experience in criminal and traffic defense."
DUI and DWI Attorney | Oct 18
Relationship: Fellow lawyer in community
"Jon remains a perennial leader as a lawyer, teacher and thought leader in protecting citizens from government overreach. At the same time he is a true gentleman scholar as a counselor for clients during their more difficult hardships. A career advocate for when everything matters, he has my highest confidence and endorsement as an attorney."
DUI and DWI Attorney | May 16
Relationship: Fellow lawyer in community

From his business cards that show his dedication to this area of law to his experience as a co-graduate from the Trial Lawyer's College, I without a doubt recommend Jon to any person in the Fairfax area and surrounding communities. I'm confident you'd be in great hands!"
Criminal defense Attorney | Mar 17
Relationship: Fellow lawyer in community
"I endorse this lawyer. Jon never gives in. He keeps at it until he gets the best results for his clients. Sometimes, that means going to trial. Other times, it means persuading the prosecutor to drop or reduce charges. Always has client's best interests dictate his approach."
Criminal defense Attorney | Nov 11
Relationship: Fellow lawyer in community
"I recently had the pleasure of meeting Jon Katz and was extremely impressed with his passion and dedication to his craft. He's a true criminal defense lawyer through and through. 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."
Criminal defense Attorney | Oct 05
Relationship: Worked for lawyer
"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."

Criminal defense Attorney | Nov 24
Relationship: Fellow lawyer in community
"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"
