  • Ryan Anton Jacobsen

    David is a very energetic and motivated attorney who is very knowledgeable in DUI defense. I consult with him on matters where criminal law might come up in my civil and probate court cases. For those reasons, I refer anyone in need of an effective criminal defense attorney to David Lousteau.

  • Alexander Frederick Frix

    I've personally seen David in the courtroom fighting for his clients. In the face of difficult opposing counsel and unyielding judges, he's obtained not guilty verdicts and other great outcomes for his clients. I endorse his work.
