      University Park Criminal Defense Lawyers

      University Park is an independent municipality of approximately 25,000 residents entirely surrounded by the City of Dallas in Dallas County, sharing enforcement jurisdiction with Highland Park under the Highland Park Department of Public Safety. The University Park Police Department enforces DWI and criminal laws along Preston Road, Northwest Highway, University Boulevard, and Lovers Lane. Every criminal and DWI case arising from University Park is prosecuted by the Dallas County District Attorney’s office and heard at the Frank Crowley Courts Building.

      Deandra Grant Law’s Dallas office at 3300 Oak Lawn, Ste 700 which is minutes from the Frank Crowley Courts Building where University Park 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: Texas DPS Crime Lab in Garland for Highland Park DPS arrests. GC-FID methodology, in vitro fermentation, sodium fluoride adequacy, chain of custody, analyst qualifications 
      • Drug cases: DPS Austin, Armstrong Forensic Laboratory, or NMS for drug analysis. Presence is not impairment. 
      • 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 

      Dallas County Courts and Enforcement

      Courthouse: Frank Crowley Courts Building, 133 N. Riverfront Blvd., Dallas, TX 75207.

      District Attorney: Despite its independent municipal status, all University Park cases are prosecuted by the Dallas County DA’s office. The city’s professional and academic community (adjacent to Southern Methodist University) means criminal charges carry significant collateral consequences for careers, licensing, and community standing.

      Federal cases: Dallas County is in the Northern District of Texas. Attorney James Lee Bright handles federal defense in the Northern District.

      Enforcement in University Park

      • Highland Park Department of Public Safety (HPDPS) serves both University Park and Highland Park
      • Dallas County Sheriff’s Office
