Aggressive Criminal & DWI Defense Attorney in Katy, TX
You have been arrested for DWI or are facing criminal charges in Katy, the Energy Corridor, or anywhere in Harris, Fort Bend, or Waller County. The traffic stop, the late-night phone call, the badge at your door — it has all put your record, your job, and your family on the line. Meanwhile, the State of Texas is already building its case against you, and every hour without an attorney is one the prosecution uses to its advantage.
Without an aggressive Texas criminal defense attorney, you risk an automatic ALR license suspension, mandatory minimum jail time on enhanced DWI or felony charges, thousands of dollars in fines and DPS surcharges, ignition interlock requirements, lost employment and professional licensing, and a permanent criminal record that will surface on every background check, lease application, and immigration filing for the rest of your life.


Your Defense Strategy
Challenging the Evidence
We obtain and dissect every piece of state evidence: offense reports, dash and body cam footage, 911 audio, field sobriety video, breath-test logs, and witness statements. We file motions to suppress illegal stops, warrantless searches, Miranda violations, and constructive interrogation — holding Texas law enforcement to the procedural standards they often cut corners on.
The DWI Edge — Attacking the Science
Breath and blood tests are not infallible. We challenge Intoxilyzer 9000 calibration logs, blood-draw chain of custody, lab analyst qualifications, NHTSA-standardized field sobriety test administration, and rising-BAC and source-of-error defenses. When the science doesn't hold up under cross-examination, charges get reduced — or thrown out entirely.
Trial-Tested Experience in Harris & Fort Bend Courts
With over two decades of Texas trial experience and admission to the U.S. District Court for the Southern District of Texas, Bob Mueller has stood before Harris, Fort Bend, and Waller County juries and judges. He knows how local prosecutors charge and plea these cases — and that insider perspective is the difference between a generic plea deal and a real defense.

Results We Fight For
Reduced or Dismissed Charges
Through motions to suppress, evidentiary challenges, and skilled plea negotiation, we work to reduce DWI, drug, and felony charges to lesser offenses — or get them dismissed entirely — whenever the evidence and procedural record support it.
Protected Driving Privileges
From the 15-day ALR deadline to occupational driver's license petitions, we move quickly to keep you behind the wheel so an arrest doesn't cost you your job, your commute, or your responsibilities to your family.
Avoidance of Jail Time
Where conviction is unavoidable, we negotiate for probation, deferred adjudication, pretrial diversion, and alternative sentencing programs instead of incarceration — protecting your liberty and your career.
A Clean Record Going Forward
When you qualify, we pursue expunction or an Order of Nondisclosure under the Texas Code of Criminal Procedure so the arrest does not follow you onto every background check, lease application, and job interview for the rest of your life.
Clear Communication at Every Stage
You hear directly from your attorney — not a case manager — about every court setting, plea offer, motion, and strategic decision, so you always know where your case stands and what comes next.
