Overview
Deandra Grant Law – Allen serves clients across Collin County and the surrounding communities who are facing DWI, criminal, and federal charges. Our office at 1333 W. McDermott Drive is your Collin County home base, right in the community and minutes from the Russell A. Steindam Courts Building in McKinney, where every Collin County criminal case is heard. Collin County is an active prosecution jurisdiction with seven County Courts at Law and fifteen District Courts and well-prepared prosecutors, so it helps to have a trial-ready defense team that knows these courts and the judges in the building.
The firm’s edge is a science-first approach to the evidence. Managing Partner Deandra Grant is an ACS-CHAL Forensic Lawyer-Scientist with a Master’s Degree in Pharmaceutical Science, and our attorneys challenge breath and blood testing at the level of the chemistry rather than relying on legal argument alone. That can change the direction of a Collin County DWI case. Use this page for our address, hours, and directions, or call anytime for a free, confidential consultation.

My son was facing possible prison prison time, I was afraid. But by the Grace of God I found Deandra Law Firm where Doug and Jada both worked awesome deals for my son in both counties he was facing..no prison. Thank you for being team Vick for us
Deandra Grant Law is top-notch! I was provided with great resources from day one. Elena was also super helpful and patient! They're the perfect team to guide you through a tough time.
Kevin and Oliva took care of me every step of the way for my case. Very educated staff. They answered every question I had promptly and informed me of everything I needed going forward. Hope to not need their services again but if I do I’ll be coming back!

Frequently Asked Questions
Where will my Collin County case be heard?
Most Collin County misdemeanor and felony criminal cases are heard at the Russell A. Steindam Courts Building in McKinney. Our Allen office is just minutes away off US-75, and your attorney appears in those courts regularly.
I was arrested for DWI in Collin County. What is the first thing I should do?
Two clocks start at once. You generally have only 15 days from your arrest to request an ALR hearing to protect your driver’s license, and the criminal case proceeds separately. Call us right away so we can request the hearing on time and start reviewing the evidence before your first court setting.
Do I have to come to the Allen office, or can we meet remotely?
Both work. Many clients prefer an in-person consultation at our Allen office, but we also handle initial consultations by phone or video so you can get advice immediately, even before you are able to come in.
How much does a consultation cost?
Consultations for DWI and criminal matters are free and confidential. You will speak with someone who can explain your charges, the likely process in Collin County, and your options, with no obligation.
Can you handle a case if I was arrested outside Collin County?
Yes. From our Allen office we represent clients across North and Central Texas and coordinate with our other locations. If you were arrested in a neighboring county, we can still take your case and route it to the attorney and courthouse that fit.
What kinds of cases does the Allen office handle?
DWI and DUI, drug charges, assault and family-violence allegations, theft, and a range of state and federal criminal matters. If you are unsure whether we handle your specific charge, call and ask, and we will tell you honestly.
