David S Katz

About me

I am the only BOARD CERTIFIED DUI DEFENSE EXPERT with offices in Orlando, Tampa, Gainesville, Tavares and Longwood.  Further, I am one of only three Board Certified DUI Defense Experts in the state of Florida.  I am nationally recognized as a DUI Defense Expert by the National College for DUI Defense which is accredited by the American Bar Association.  I have authored or co-authored 6 books on DUI defense including two training manuals used by other lawyers to learn to defend DUI cases.  I enjoy what I do for a living.  I am constantly reading books on DUI defense techniques and remain on the cutting edge of DUI defense.  I also enjoy attending numerous seminars throughout the year on DUI defense and scientific evidence.  My association with the National College for DUI Defense allows me access to lawyers and expert witnesses throughout the country who can provide help to tailor a custom defense to your needs. Although an application is pending with the Florida Bar,  DUI is not yet recognized as a specialized area of law in Florida, therefore please note that I am not certified as a specialist by the Florida Bar.

  • Frederick William Trabold III

    I had the pleasure of working with Mr. Katz in fighting the intoxilyzer 8000 in Lake County. There are attorneys that handle DUIs and there are DUI attorneys. While it may costs a bit more, there is a huge difference between the two. If you have been arrested for DUI, there are only a small handful of attorneys who truly have an understanding of all the complex legal issued involved in a vigorous DUI defense. Mr. Katz is not only one of the smartest DUI attorneys, he also has the ability to articulate these complex issues in a manner that juries can understand.
