      Celina DWI and Criminal Defense Lawyers

      Celina is one of the fastest-growing communities in North Texas, situated along US-75 (Central Expressway), Highway 289 (Preston Road), and FM 455 in northern Collin County. The Celina Police Department actively patrols US-75, Preston Road, FM 455, and Punk Carter Parkway, with DWI enforcement a consistent priority. Celina sits primarily in Collin County, with a small portion extending into Denton County. That means that  most cases are heard in McKinney, but cases arising from the Denton County portion go to the Denton County Courts Building.

      Deandra Grant Law’s Allen office is at 1333 W. McDermott Drive, Suite 180 which is minutes from the Russell A. Steindam Courts Building at 2100 Bloomdale Rd., McKinney, where Collin County criminal and DWI cases are heard.

      Managing Partner Deandra Grant holds a Master’s Degree in Pharmaceutical Science, a Graduate Certificate in Forensic Toxicology, and the ACS-CHAL Forensic Lawyer-Scientist designation. Partner Douglas Huff holds the same ACS-CHAL designation and has completed advanced digital forensics training. For federal matters in the Northern District of Texas, Of Counsel James Lee Bright brings more than 25 years of federal trial experience.

      Why the Science Behind Your Case Matters

      Most defense attorneys challenge DWI and criminal evidence through legal argument. Deandra Grant Law challenges it through the science. 

      • Blood testing: Collin County alcohol DWI blood draws typically go to the DPS Garland lab. Drug cases route to DPS Austin, Armstrong Forensic Laboratory, or NMS. GC-FID methodology, in vitro fermentation, sodium fluoride adequacy, chain of custody, analyst qualifications
      • Breath testing: Intoxilyzer 9000. Partition ratio variability (1,100:1 to 3,400:1), 15-minute observation period compliance, calibration records, mouth alcohol, GERD/diabetes effects.
      • Field sobriety tests: Deandra Grant is a trained SFST instructor who administers and grades the ACS-CHAL Forensic Lawyer-Scientist and DUIDLA Board Certification exams. SFST cross-examination goes to the protocol, not just the result.
      • Digital evidence: Cell phone data, social media, CDR records, surveillance footage 
      • Retrograde extrapolation: Rising BAC defense, Widmark formula, individual elimination rate variability

      Criminal Defense in Collin County

      Every criminal defense in Collin County begins with Texas Code of Criminal Procedure Article 38.23 which is the exclusionary rule with no good faith exception. An unlawful stop, a defective warrant, a search beyond its scope: any of these can suppress the evidence driving the prosecution’s case. Along US-75, Preston Road, and the other Celina enforcement corridors, the stop analysis is often the most important question.

      We handle the full range of criminal charges arising from Celina and Collin County:

      • Assault and family violence — including the permanent consequences of the family violence affirmative finding
      • Drug possession and delivery — DPS Garland / DPS Austin / Armstrong / NMS lab analysis challenged at the chemistry level
      • Theft, robbery, fraud, and white-collar offenses
      • Gun crimes — UCW, felon in possession, federal firearms charges
      • Sex offenses — forensic evidence and digital evidence examined independently
      • Murder and homicide — through capital murder
      • Federal criminal defense — Eastern District of Texas, handled by James Lee Bright

      Frequently Asked Questions After an Arrest in Celina, TX

      Yes, and it is often one of the most valuable pieces of evidence in a DWI case. Dashcam footage from the patrol vehicle and body camera recordings capture the driving behavior that led to the stop, the officer’s interaction with the driver, and the administration of any field sobriety tests. When that footage contradicts the officer’s written report — or shows the tests were administered improperly — it can significantly affect how the case proceeds. We request this footage through discovery as early as possible, since recordings can be overwritten or lost if not preserved promptly.

      Yes. Texas DWI law applies to any substance that causes a person to lose the normal use of their mental or physical faculties, including legally prescribed medications. Sedatives, muscle relaxants, sleep aids, antihistamines, and certain pain medications can all form the basis of a DWI charge even when taken exactly as prescribed. Defense strategies in these cases often focus on challenging evidence of impairment, demonstrating lawful and proper use of the medication, and presenting medical testimony regarding the drug’s actual effects at the levels present in the defendant’s system.

      Missing a scheduled court date in Collin County typically results in the judge issuing a capias — a warrant for your arrest — and potentially forfeiting any bond you posted. The longer a warrant remains outstanding, the more complicated the situation becomes. If you have missed or are at risk of missing a court date, contacting an attorney promptly gives you the best opportunity to address the warrant, reinstate your bond, and get your case back on track without additional consequences.

      It can be a relevant factor. Celina’s rapid growth has brought significant construction activity, new road layouts, freshly paved surfaces, and signage changes that are not always fully established. Accident-related DWI cases in particular may involve road conditions, drainage issues, or poorly marked construction zones that contributed to what law enforcement attributed solely to driver impairment. Independent accident investigation sometimes surfaces these alternative causation factors, which can be meaningful to the defense.

      An ignition interlock device (IID) is a breath-testing unit installed in a vehicle that prevents it from starting if alcohol is detected on the driver’s breath. In Texas, IIDs are mandatory for DWI convictions involving a BAC of 0.15 or higher, for second and subsequent offenses, and in certain other circumstances. They are also frequently imposed as a condition of bond or probation. The device requires regular calibration checks and generates a log that is monitored by the court — violations can result in additional legal consequences.

      Hospital blood draws occur frequently when a DWI suspect is injured and receives medical treatment following an accident. These draws present distinct legal issues compared to draws performed specifically for law enforcement purposes. Questions about whether the draw was taken for medical purposes or at law enforcement’s direction, whether proper consent or a warrant existed, and whether the hospital’s handling procedures meet the standards required for evidentiary use are all potentially significant. The source and circumstances of a blood draw matter considerably in how the evidence can be challenged.

      It can. A clean record is a relevant factor in plea negotiations and, if the case goes before a judge or jury, in sentencing. First-time offenders in Collin County may also have access to pretrial diversion options or deferred adjudication for qualifying charges that would not be available to someone with a prior record. While no outcome is guaranteed, a first-time charge with no prior history generally provides more room to work with than a case involving prior convictions.

      With a regular conviction, guilt is formally established and the conviction becomes part of your permanent criminal record. With deferred adjudication, the court defers a finding of guilt while you complete a supervision period. If you successfully complete the terms, the case is dismissed without a conviction. However, deferred adjudication in Texas is not the same as an expunction — the arrest record and deferred adjudication itself may still appear in background checks and may be used against you in future cases. Not all DWI charges qualify for deferred adjudication in Texas.

      Yes, and it is one of the most consequential issues in any DWI defense. Under the Fourth Amendment, an officer must have reasonable suspicion of a traffic violation or criminal activity before stopping a vehicle. If that threshold was not met, a motion to suppress can challenge all evidence gathered as a result of the unlawful stop — including field sobriety tests, officer observations, and chemical test results. Patrol activity along US-75, Preston Road, and FM 455 in Celina produces a significant number of traffic stops, and the basis for each one is subject to scrutiny.

      Bond conditions in Collin County DWI cases frequently include requirements such as abstaining from alcohol, submitting to random testing, installing an ignition interlock device, and avoiding new criminal charges. Violating any of these conditions can result in a bond revocation hearing, revocation of your release, and return to custody. If you are having difficulty complying with a bond condition or believe a condition was improperly imposed, addressing it through counsel before a violation occurs is far preferable to dealing with the consequences after the fact.
