Never misses a beat every step of the case

“thorough ” would be my word in describing attorney Jon Katz….never misses a beat every step of the case. Starting with the arrest and miranda rights, Jon examines every aspect of the case. Especially important in d.u.i. cases is the breath results which Jon examines in detail finding any procedural flaws that might happen. Jon engages the prosecution like a samurai warrior in that he can absorb their attacks, and yet offer brilliant strategies in a calm manner. His years in court offer a perspective about the judge, jury and prosecution that are of priceless importance when mounting a defense. His daily blog on facebook is a great way to experience real life court . I would highly recommend this attorney for all legal matters.

Jon was very responsive and portraying expert knowledge provided a relief in a very distressed time. Being a high standard professional he cares for the client with ease and great humor. Punctuality and compassion all throughout our communication. Outstanding result. I consider myself lucky to have met him.

His eye does not miss a detail, and is quick to point out discrepancies in the prosecution's evidence

fantastic attorney….defended me on a possession charge in Maryland. Was thorough and never skipped any details, I follow jon on his underdog blog, and have learned much. His eye does not miss a detail, and is quick to point out discrepancies in the prosecution’s evidence. I also enjoy his posting on trips to historical sites, as Jon is an avid fan of civil rights events, past and present…I would highly suggest hiring Jon whether it is a traffic violation, or a higher case.
