Trichter & LeGrand combines professional, aggressive criminal defense with caring, understanding legal counsel. This winning combination gives clients peace of mind that their cases are in the hands of a capable Texas DWI Lawyer. The firm was founded by Houston DWI lawyer J.

Since 1980, Gary has defended Texans concerned with preserving their valuable reputation. In fact, Gary co-authored the textbook Texas Drunk Driving Law, and has authored or co-authored 46 legal and aviation articles.

Our Founder Gary Trichter was the 1st DWI Specialist in the State of Texas. He is one of only four DWI Specialists in Texas.

The Texas Bar Association has no DWI board certification, but it does recognize the ABA DWI board certification. There are only four Texas attorneys with this certification, and two of them call Trichter & LeGrand home.

If you need a Texas DWI Lawyer, Trichter & LeGrand  can help you if you’ve been charged with driving while intoxicated (DWI), driving under the influence (DUI), boating while intoxicated (BWI) or flying while intoxicated (FWI), or if you face an administrative license revocation (ALR) hearing.
