About me

    • I was one of 6 people in the State of Florida and the only DUI defense lawyer in
      the State of Florida that was asked by the Florida Department of Law
      Enforcement (FDLE) to assist in writing the FDLE DUI curriculum.

    • I was named a Special Prosecutor by the State of Florida to argue DUI cases in Orange, Osceola,
      Seminole, Volusia, Brevard, Hernando, Marion, Alachua, Broward, Lee,
      Collier and Monroe counties.

    • I was named a Lead DUI Prosecutor by the Orange/Osceola County State Attorney’s Office (9th Judicial Circuit – Orlando).

    • I  co-authored the book that is used to train every law enforcement officer in the State of Florida when it comes to making DUI arrests.

    • I have trained thousands of prosecutors and law enforcement officers throughout the State of Florida on DUI prosecution and DUI investigation.

    • I have attended the same classes that law enforcement officers attend in order to properly administer field sobriety exercises and the breath test.

  • Jordan Michael Ostroff

    I endorse this lawyer, you cannot ask for a more knowledgeable and experienced DUI attorney than Matt - he still gives training to the police from time to time, so who better to know when the cop has made a mistake that he can jump on at a hearing or trial.

    Matt really knows his stuff especially when it comes to DUI. He has the respect of the State Attorneys Office from his work as the head DUI prosecutor during his time as an Assistant State Attorney.
