    Jeffrey Denner is the best criminal defense attorney in the country. I have observed him to be compassionate, dedicated, and sharp in the courtroom.

He is the kind of lawyer who does his best, and excels tirelessly. Because of this, Jeffrey Denner is adept at helping others, and solving problems. His firm provides excellent representation, with elite legal teams, world class experts and top investigators. Jeffrey Denner is exceptional. I endorse this attorney.
