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: Dallas, our headquarters, plus Allen, Denton, Fort Worth, Rockwall, and Waco, and we appear in the county courts around each of them. You do not need to choose one. Call any number on this page and intake will route your case to the attorney and office closest to the court where your charge is pending. Addresses and directions are in our locations.

The firm holds a 4.9 rating across more than 600 Google reviews, collected across all six offices, 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.
