For 30+ years, Texans facing DWI, criminal, and federal charges have trusted Deandra Grant Law. Six offices statewide, forensic-trained trial attorneys, and a record of dismissals and not-guilty verdicts.

Doug spent extra time talking with me about the case... With their help, I was able to retain my driver's license for the 21-month period between my arrest and the final hearing. I was also able to avoid going to jail.
I was looking at a possible 24 months supervised probation but this team worked magic and got me 16 months! Amazing, highly recommended to anyone who is having doubts about their DWI case
Felony dismissed
My case was DISMISSED most importantly! A special thank you to Deandra, who went above and beyond by sending me a handwritten letter — such a thoughtful gesture.
Both felonies were dropped within the year. I am now back in the home working diligently on bettering the relationship with my daughters. I am grateful for Doug.
I was found not guilty at my trial. Douglas and Mckenzie did a fantastic job representing me. If you ever get a DWI hire them immediately.
The grand jury no billed my felony case. My misdemeanor was dropped. I am eternally grateful to the whole team at Deandra Grant Law.
