Overview
Texas DWI Defense from Deandra Grant Law
You can be charged with DWI in Texas for operating a motor vehicle in a public place while intoxicated, whether that means a blood or breath alcohol concentration of 0.08 or higher or losing the normal use of your mental or physical faculties because of alcohol or drugs. If convicted, you can face jail, heavy fines, a license suspension, and a permanent record. A high BAC, a child passenger, a prior conviction, or a crash that injures someone can raise the charge all the way to a felony DWI.
But an arrest is not a conviction. Every DWI case is built on science, and that science is often flawed. Deandra Grant Law is led by a forensic lawyer-scientist who wrote The Texas DWI Manual and trains DWI attorneys across the state. We've tried more than 500 cases to verdict, and we take the State's evidence apart at the chemistry level.
The consultation is at no cost to you, and the sooner we start, the more we can protect. Call or book online and tell us what happened.
15-Day Deadline
Your License Is on a Separate 15-Day Clock
Your license case runs separately from the criminal case, and the 15 days start when you receive the notice of suspension, not automatically at arrest. In a blood case that notice is often mailed weeks later. If nobody requests a hearing in time, the suspension takes effect on its own.

All Case ResultsWhy Deandra Grant Law
What Sets This Defense Apart
Every firm says it will fight for you. What actually decides a DWI case is how well your lawyer understands the evidence.
Forensic Lawyer-Scientists
Two ACS-CHAL Forensic Lawyer-Scientists on staff, plus a Master's in Pharmaceutical Science and a graduate certificate in forensic toxicology. The State's chemistry gets attacked at the chemistry level.
Trained SFST Instructor
Deandra Grant trains other attorneys on standardized field sobriety testing and grades their board certification exams, then takes that testing apart on cross, down to the four-second hold.
17 Published Law Books
Including The Texas DWI Manual, the James Publishing treatise other Texas defense attorneys keep on their desks.
500+ Cases Tried to Verdict
More than 500 cases tried to verdict since 1994, all of it DWI and criminal defense.
Former Prosecutor
Deandra Grant prosecuted DWI cases as a Dallas County Assistant District Attorney. She knows how the State builds them because she used to build them.
Mitigation at No Cost
Full mitigation reports with clinical assessments, included in your representation. Work that typically runs several thousand dollars when hired out separately.
After You Hire Us
What We Actually Do on Every Case
From the first call, in order:
- Request your ALR hearing before the 15-day deadline and use it to question the officer under oath
- Demand the dash and body camera video before it’s destroyed
- Pull the full discovery file: offense report, calibration and maintenance logs, lab records, certifications
- Read the underlying chemistry ourselves: the chromatograms, the QC data, not the summary report
- Re-score the field sobriety tests against NHTSA protocol, on video
- File the motions the evidence supports, because suppression is how DWI cases end
- Build your mitigation file, with clinical assessments, at no cost to you
- Try the case if the offer isn’t right, which is why the offers get better
We quote a flat fee after a consultation at no cost to you, so the investment is known before you commit.
