I have a friend who deals with DWI/DUI in Dallas specifically. You don't need a conviction, and he is really great and getting people off without a conviction. Give him a call and he could tell you what he thinks about your case and how it could effect you. His name is Wesley Cordova and his cell number is 281-635-9734. I used him when my son was in a jam with his first DWI. Good luck!
