For Trey Porter, Getting a DWI Dismissed Is Only Half the Fight

For one public-school teacher, a DWI conviction threatened far more than fines, probation, or the loss of driving privileges. It meant immediate termination. When prosecutors would not offer a resolution that protected the teacher’s livelihood, the case was prepared for trial. On the day the jury was set to hear it, the charge was dismissed. The arrest was later expunged, leaving the teacher without a criminal record.

That outcome captures the defining idea behind Trey Porter’s practice: defeating the charge is the first objective, but protecting what happens afterward can be just as important.

Porter founded Trey Porter Law in 2017 and built it around a deliberate concentration on DWI, Public Intoxication, and criminal-record clearing. He has handled more than 1,000 criminal and intoxication-related matters across Texas, representing people whose employment, professional licenses, driving privileges, reputations, and futures may depend on the result. Rather than presenting himself as a criminal-defense lawyer who handles everything, Porter has developed a practice centered on a narrow group of cases and the evidence that determines them.

That evidence can be highly technical. Porter has completed practitioner-level training in standardized field sobriety testing and advanced instruction involving breath-alcohol analysis, blood testing, gas chromatography, infrared spectroscopy, and retrograde extrapolation. That background helps him examine whether an officer’s conclusions agree with the video, whether an arrest was supported by probable cause, and whether laboratory evidence can withstand scrutiny.

His results show why that preparation matters. A military veteran facing a second DWI and as much as one year in jail saw the charge dismissed on the day of trial after the defense challenged the State’s ability to prove marijuana use and impairment. In another case, police claimed that a defective taillight justified the traffic stop; video contradicted the report, the charge was dismissed, and the arrest was later expunged. Porter’s firm also defeated a high-alcohol-concentration DWI prosecution after challenging blood evidence that the State ultimately did not use.

Public Intoxication is an especially strong part of Porter’s record. Every Public Intoxication case he has accepted has ended in dismissal, and none of his clients has been convicted of the offense. That record carries particular importance for teachers, physicians, nurses, service members, students, and other professionals who may face consequences extending well beyond a Class C misdemeanor.

Porter also understands that dismissal alone does not automatically remove an arrest from public view. If the case qualifies, he can ask the court to erase the arrest record through an expunction. If the record cannot be erased, he may still be able to have it sealed and removed from most public background checks. Porter’s firm has obtained both outcomes even when prosecutors or the Texas Department of Public Safety tried to block the request.

Professional recognition and public feedback reinforce Porter’s reputation as well. Porter was selected to the Texas Rising Stars list from 2022 through 2024. More significantly for consumers, he maintains a perfect 5.0-star Google rating based on 276 reviews. Sustaining the highest possible rating across hundreds of public evaluations provides substantial validation from the people who have experienced the firm’s work firsthand.

Trey Porter’s value lies in the precision of his focus. He knows that an intoxication arrest can threaten a career before the case ever reaches trial—and that even a dismissal may leave a damaging public record behind. His practice is structured to confront both problems: fight the accusation, then clear the record whenever Texas law allows it.

That combination of experience, reputation, verified professional standing, and public credibility is why James Kenneth “Trey” Porter III was included on FreddieFender.com.
