Criminal charges we defend

Every case we take on gets filed, studied, and fought the same way, with a strategy built for the specific charge you are facing.

Discuss Your Case

All charges we defend

Murder & Assault

Homicide, aggravated assault, and deadly weapon charges. Sam has tried first degree felony cases to a jury verdict, including the Barajas acquittal in Brazoria County.

Where We Practice

Harris County and nearby courts

A criminal case is heard where it was filed, not where you live. That is why the county matters more than the city: the prosecutors, the bond practice, and the diversion programs are different in each one.
