Texas DWI & Criminal Defense,
Backed by Forensic Science

Both. DWI defense has been the core of the practice since 1994, and the same attorneys handle the full range of Texas criminal charges, from assault, drug, and weapons cases to federal matters. What carries across every case is the science. The partners are trained to challenge blood, breath, and lab evidence at the chemistry level, and that forensic approach shapes how we defend a DWI and a felony alike. See our Texas DWI defense and criminal defense practices.

It is a credential awarded through the American Chemical Society’s Chemistry and the Law division (ACS-CHAL) to attorneys who complete graduate-level training in the science behind forensic evidence, including blood alcohol analysis, gas chromatography, and breath testing. Both partners, Deandra Grant and Douglas Huff, hold it. In practice it means we read the lab’s own data instead of taking the State’s number at face value, and we know where the testing goes wrong. Meet our attorneys.

We have six offices, and the county where your case is filed decides which one handles it. Dallas County and Ellis County cases go to our Dallas headquarters; Tarrant and Johnson County to Fort Worth; Collin and Grayson County to Allen; Denton and Cooke County to Denton; Rockwall and Kaufman County to Rockwall; and McLennan, Bell, and Coryell County to Waco. Cities on a county line, Frisco, Carrollton, and Richardson among them, are handled by whichever of those offices covers the county of the arrest. You do not need to choose: call any number on this page and intake routes your case to the attorney and office closest to the court where your charge is pending. Addresses and directions are in our locations, and each county’s courts are covered in the county guides.

The firm holds a 4.9 rating on Google across its six office listings, and every review shown on this site is verified on Google. Clients most often mention the same things: an attorney who explained the case honestly, a fee that matched the quote, and being treated like a person rather than a file. Read them in our reviews or on any office’s Google profile.

Intake answers 24/7. During the day you reach our staff, and after hours an answering service takes your details so nothing waits until morning. Intake asks about the charge, the county, and your court date, at no charge and in confidence. If your case is one we can take on, we schedule a free consultation with an attorney, who will explain your options and quote a flat fee up front. No pressure and no obligation.
