A DWI arrest in Flower Mound can be particularly devastating because of the community’s professional demographics. Many Flower Mound residents hold positions that require security clearances, professional licenses, or corporate background checks, all of which can be affected by a DWI conviction. Our ACS-CHAL Forensic Lawyer-Scientist credentials and SFST training give us the scientific tools to challenge the prosecution’s evidence and fight for outcomes that protect your career and your future.
Why the Science Behind Your DWI Matters
Most DWI defense attorneys challenge procedure. Our forensic training allows us to challenge the science itself:
- Blood testing: GC-FID methodology, coelution, contamination, in vitro fermentation, improper blood draw procedures
- Breath testing: Partition ratio variability, mouth alcohol contamination, GERD/diabetes false positives, Intoxilyzer 9000 limitations
- Field sobriety tests: NHTSA protocol challenges, administration and scoring errors
- Retrograde extrapolation: Challenging the prosecution’s BAC calculations

The 2019 DWI Law Changes
If your BAC was below 0.15 (or no test was obtained), you may be eligible for deferred adjudication which results in the possibility of a dismissal and the ability to seal your record. If your BAC was 0.15 or higher, conviction for this Class A misdemeanor will lead to a permanent conviction. Our training is the tool that can challenge BAC accuracy near the 0.15 threshold.
