    Glynn is a nationally renowned DUI trial lawyer because of his natural ability to persuade prosecutors, judges, and juries, his tireless dedication to staying on the cutting edge of DUI defense, and the unmatched results he achieves in the courtroom. If I had a friend or family member charged with DUI anywhere in Louisiana, I would make sure they called Glynn to defend them.

    I know quality and class when I see it. I can share with you that Attorney Delatte not only has both of those qualities, but much more. He is a true litigator. He has the requisite reputation, knowledge, experience and guts to make a real difference in the lives of the motorist accused of a DUI or related offense. Attorney Delatte has earned a true national reputation for minimizing or eliminating the accusations of the government against the motorist accused. I trust him. I know you will too.
