Experienced DWI and Criminal Trial Attorney

     At the Law Office of Derk A. Wadas, I have been practicing DWI and criminal law exclusively since 1999, first as a prosecutor and now as an attorney representing citizens accused of crimes.  In 2005 I founded The Law Office of Derk A. Wadas with the goal of providing superior DWI and criminal defense representation.  I am able to accomplish that goal, in part, by deciding to focus on criminal law and procedure exclusively, with a strong emphasis on DWI and Intoxication Offense.  I have a proven track record of obtaining favorable results for clients.  For a few examples,  please view the Recent Results portion of this website.

As a prosecutor from 1999 to 2005, I tried over seventy five cases to a jury and handled hundreds more successfully.  As a defense attorney, I have tried many, many more cases and have achieved numerous not guilty verdicts, charge reductions and outright dismissals for my clients.   
 
It is very important to me to remain at the forefront of the developing law and defenses in my field.  For this reason I am a member of organizations such as the National College for DUI Defense and the Texas Criminal Defense Lawyers Assocation.  Further, I have completed the Standardized Field Sobriety Testing practioner course.  I have the same training in field sobriety testing as the police who are investigating DWI cases.

  Below I have listed just some of the continuing education courses I have taken recently.  Many, though not all, deal specifically with the defense of DWI and Intoxication related offenses.
