- NATIONALLY-RECOGNIZED BY MAJOR MEDIA
"Jon Katz is the greatest lawyer on the face of the planet. I say so because he dealt with not only my criminal case, but my rattled emotional state of mind as well. Without his guidance and brilliance I don't know what would've happened. I highly recommend Mr. Katz, and if I ever make the mistake of getting arrested again he will be the first person I call." (From a criminal defense client.)
"In my case Jon Katz produced results that only he could achieve. His amount of preparation and research clearly made a huge difference. He took the fight to the prosecutor from the first moment he was retained, keeping his foot on the prosecutor's neck the entire case, from bail to discovery to sentencing. I was facing 5 years in prison, and the loss of my job and home.... Thanks Jon, Jay and Staff. You are quite simply the best. [See the rest of this testimonial here.] ( From a criminal defense client.)"
"This testimonial serves as not only a heartfelt thank you for your outstanding legal representation, but as a call to others facing the harshness and unfairness of our legal system. To anyone in the unfortunate position of possession of marijuana, there is no one else you should consider for representation than Jon Katz. The state of Virginia and law enforcement is bordering a third world nation in attitude and enforcement of the most minor of offenses, including simple possession. That state’s law enforcement’s giddiness over any arrest for anything strikes unimaginable fear in even the most grounded and strong individuals.
"Not only did I witness your brilliance in working the courts, prosecutors, judges, and state troopers, but it served as an inspiration, a call to activism, a call to not simply survive within the system, but to change it.
"Your courage, fearlessness, and commitment to the little guy serves as the last bastion of goodness in a legal system gone awry. You are a rare find, a legal warrior, a philosophical giant among those with no other agenda than power over others. I will act as a reference anytime and would march into a verbal, legal, or any battle with you shoulder to shoulder, with confidence.
":My eternal gratitude." (From a criminal defense client).
"Jon is a tireless fighter for justice. He represented community organizers free of charge who were arrested at actions on the City of Baltimore and on the Governor of Maryland. He is a protector of free speech, dignity for poor people, and fairness for everyone. I recommend Mr. Katz to anyone needing aggressive and smart legal representation." Mitch Klein, Maryland ACORN Head Organizer.
"Jonathan Katz is compassionate and understanding to his people and to his clients. He did not treat me like a number or a dollar sign but instead he is always present and pays attention and he is very professional. I would certainly recommend him to anyone else ." (From a criminal defense client).
"Jon, you are the best attorney in the world as far as I'm concerned. Thanks again for your work on my behalf and your optimistic energy." (From a criminal defense client).
"As a forensic accountant and investigator of white-collar crime, the last thing I needed to deal with was a DWI charge. If this charge resulted in a conviction, or public disclosure, my career would be in jeopardy. My fears and anxieties were relieved once I retained Jon Katz and his firm. Jon's competence, professionalism and deep understanding of the criminal justice system and DC Courts, provided me with a sense of confidence that all would be well at the end of the day. Thanks to Jon, all is well!" (From a criminal defense client).
"Jon and his staff were meticulous, dedicated, and determined to ensure my rights as a citizen were fully maintained during my case. He laid out several scenarios on how things could proceed and stuck to the one that we both felt had the highest likelihood of success of maintaining my innocence - which was the end result. While I was financially constrained, Jon worked with me to ensure I had the best defense I could, which was more than I ever imagined! I keep Jon's card in my wallet and highly recommend him to anyone needing legal services." (From a criminal defense client).
"My son and I both want to thank Jon Katz for his hard work on my son's probation violation cases in two different counties. Mr.. Katz's legal skill allowed my son to enter rehab and start getting his life back together instead of sitting in a jail cell. For that we are more than grateful. Mr. Katz took the time to work personally with both us (calming a stress-out mother), craft the right strategy and pull it all together. Thank you from a grateful mother and son." (From a criminal defendant's parent).
2. "Many
thanks to a savvy attorney. Jon
Katz represented me in connection with speeding and suspended license charges on
Federal land in southern
"The thing that impressed me the most about Jon was his integrity, his enthusiasm for his work and his ability to understand the total situation as it was and present it to the prosecutor and arresting officer in the most favorable light.
"Jon's ability to deal with the prosecutor and his negotiation strategy allowed us to plead to a much lesser charge and saved me from months of pain and suffering.
"In
summary, I felt I was extremely well represented by Jon and truly appreciate Jon
taking the case even though it was a considerable distance from
Mr. Katz has provided excellent service at competitive price for my case. Everything went on just as what he described in our initial meeting. I'm so satisfied with the outcome, and I'd strongly recommend this attorney! I really appreciate your effort you put in my case, Jon." (From a criminal defense client).
"My grandson was picked up by PG Police on three warrants filed by the Chesterfield, Virginia Police. The charge was utterance of larceny. Someone cashed a stolen check using his name and identification. He spent 13 days in the PG jail until the Chesterfield police picked him up and took him to Virginia. He had no way of proving his innocence. The charges carried a 30 year sentence. Mr. Katz had many conversation with the District Attorney in Chesterfield and finally convinced him to check my grandson's fingerprints against those on the forged check. The prints proved to belong to someone else. He got the charges dropped. Without Mr. Katz's hard work and devotion to his clients my grandson would have faced jail because of a case of identification theft." (From grandmother of a criminal defense client).
"I want to take this opportunity to highly commend Jon Katz for his hard work and sincere dedication for defending me in my DWI charge several years ago. Prior to, during and after the trial, Jon made me feel comfortable, at ease and provided me with the sense and comfort of having an experienced and professional leading attorney by my side. With Jon defending me, I did not once feel, doubt or have any hesitation about the outcome of my trial. I would like to give Jon a million thanks once again and highly recommend him to anyone in need of a real criminal trial attorney." (From a criminal defense client).
Mr. Jonathan Katz defended our son quite successfully, demonstrating professionalism and considerable expertise. He dealt directly with our young adult son, treating him with respect and openness while also helping him to understand the entire process and the need to avoid being in the wrong place at the wrong time in the future. While waiting in the court room for our son’s case to be called, we became concerned because the judge and the prosecutor seemed to be tough on a number of cases. However, when our son’s case was called, Mr. Katz spoke with the appropriate people and the court openly acknowledged that they did not have evidence or a case and dropped all the charges. While the verdict was absolutely correct, in some other cases, innocence did not seem to be as relevant. Mr. Katz is responsible for the prompt and accurate disposition and the rapid expungement. We are most grateful. (From the parent of a criminal defense client).
"I highly recommend Marks and Katz for both their professional and
personal integrity. My husband and I have had the great opportunity to
work with both attorneys and have been pleased in every way. When my husband was facing criminal charges we sought the services of Marks and
Katz after reading their outstanding resumes posted online.
"From the beginning we were warmly welcomed from both and each addressed our concerns and issues immediately. Mr Marks worked closely with Mr.
Katz during the criminal proceedings to ensure there would no negative immigration consequences. While my husband's English is fine, their
ability to speak a number of different languages helped my husband to better to understand issues. Mr Katz immediately made several
recommendations that would ultimately lower his sentence (in my opinion). He spent time to research similar cases, clearly went over
testimony and took time to answer every question in full. He was always sure to protect my husband's interests by speaking directly to him and
not through other people. While he is a very busy man with many clients we always felt like we were the only one.
"In court Mr Katz fought furiously for my husband. We had a prosecutor who was adamant on solid jail time and just would not budge on
anything. Mr Katz negotiated morning and early afternoon to obtain a more favorable settlement, which ultimately was obtained. My husband
pled guilty to a lesser charge and while we didn't go to trial, Mr Katz's' outstanding presentation to the judge allowed my husband to only
get one year probation and to avoid jail. I am very confident this would not have been the outcome if we were not in the confident hands of
Mr Katz.
"Marks and Katz truly love their jobs and have a passion for what they do and it shows in their work. They stand behind what is on their website
and offer fantastic legal representation at a very fair cost. We will always be grateful to Mr Katz for saving our family. We now look
forward to working with Mr Marks to finalize immigration matters." (From
the spouse of a criminal defense client).
"I
had an issue with with the local
government impounding my car and keeping it
unlawfully for a very extended period of
time. Mr. Katz was responsive, diligent and hard nosed
with the appropriate authorities. These qualities plus
his tenacity resulted in my property being
returned to me far faster than I would
have obtained alone. I was floundering as
to what to do. Once I contacted Mr. Katz, I felt
much more in control and was extremely
pleased with the results." (From a client whose car
was seized by the government.)
"Mr. Katz handled my case in a rapid and effective manner. It shows in his work that the idealism he describes on his website - to fight for justice - is real. The combination of his top notch professionalism and drive lead me to warmly recommend his services. May any defendant be defended by an attorney like him!" (From a criminal defense client).
