His Story

A Career Built on Both Sides of the Courtroom

Sam R. Cammack III has practiced law in Texas since 2002, building a career on both sides of the criminal courtroom. Before dedicating his practice to criminal defense, Sam served as a felony prosecutor in Harrison County, Texas, where he prosecuted hundreds of criminal cases ranging from DWI to murder. That experience gave him firsthand knowledge of how prosecutors evaluate evidence, prepare witnesses, present cases to grand juries, and build felony prosecutions for trial.

Today, Sam represents people in Houston and courts throughout the surrounding Greater Houston counties . His defense work ranges from misdemeanors and DWI and DUI to serious felony prosecutions involving murder, capital murder, and assault , drug and narcotics offenses , robbery and theft , family violence and domestic assault , juvenile matters, and other criminal charges.

Across his career, Sam reports handling more than 20 murder and capital-murder matters, with at least 16 homicide cases taken to jury trial. His courtroom experience includes acquittals, mistrials, lesser-included verdicts, dismissals, grand-jury proceedings, negotiated resolutions, and other outcomes in cases where the consequences for the accused can be life-changing.

Sam's career has been spent on both sides of a criminal case: first preparing felony prosecutions for the State, and then standing before juries defending the accused.

The State Bar of Texas attorney record lists Sam as eligible to practice in Texas and licensed since December 5, 2002, with Criminal listed as his reported practice area.
