Aggressive DUI and DWI Defense Strategies

Texas prosecutors enforce severe penalties for driving while intoxicated, including statutory driver license suspensions, substantial fines, mandatory ignition interlock devices, and incarceration. As trusted DUI and DWI defense lawyers and traffic ticket lawyers, the firm examines every detail of the initial traffic stop. Mark Lassiter challenges the validity of reasonable suspicion, field sobriety test protocols, and chemical breath or blood testing calibration standards. When motorists need an attorney urgently following an arrest, the practice moves swiftly to request Administrative License Revocation (ALR) hearings to safeguard driving privileges and pursue charge reductions or complete dismissals.

Drug Crimes, Weapons Offenses, and Violent Crime Defense

The practice defends against a broad spectrum of felony and misdemeanor offenses across state and federal courts. As skilled drug crime defense lawyers and violent crime defense lawyers, the legal team handles complex matters including:

• Drug possession, prescription medication fraud, distribution, and trafficking charges
• Assault, aggravated battery, and domestic violence defense accusations
• Theft, burglary, armed robbery, and white-collar property crimes
• Unlawful firearm carrying, weapons violations, and firearm enhancements
• Juvenile offenses, student misconduct hearings, and university Title IX claims

By identifying constitutional violations, illegal traffic stops, unlawful searches, and improper police questioning, the firm builds formidable defenses that protect clients from overzealous prosecution.

Criminal Record Expunctions and Non-Disclosures

A past criminal record or arrest history can create lasting barriers to housing, commercial employment, professional licensing, and educational opportunities. The firm assists eligible clients in clearing their legal slate through formal criminal expunctions and orders of non-disclosure. Erasing arrest records or sealing files allows individuals to move forward with confidence, free from the permanent shadow of a prior accusation.
