The Grayson County Sheriff’s Office announced last week the retirement of Chief Deputy Marty Hall. Chief Deputy Hall has dedicated 26 years of service to the citizens of Grayson County, and the office staff is thankful for his contributions to the agency and the community.
The Grayson County Sheriff’s Office is excited to announce that retired Texas Ranger Brad Oliver has agreed to serve as the next Chief Deputy. Ranger Oliver, a distinguished law enforcement professional with 27 years of service, will officially be sworn into the position on Feb. 3. Details regarding the swearing-in ceremony will be shared in the coming days.
Ranger Oliver began his career in 1994 as a Texas State Trooper, quickly advancing through the ranks.

He was a founding member of both the Texas Ranger Recon Team, tasked with combating trans-national gangs and drug traffickers along the Texas-Mexico border, and the Texas Ranger Company B Special Operations Team (SRT), leading high-risk felony warrant and search operations across Northeast Texas.
In addition to his operational roles, Ranger Oliver has provided critical training to thousands of law enforcement officers, district attorneys, and investigators across Texas. His contributions include developing a course on Officer-Involved Shooting Protocols, which has been taught to over 10,000 students statewide.
An accomplished firearms instructor, Ranger Oliver is certified by TCOLE, the NRA and Texas DPS, with extensive experience in training for pistols, patrol rifles and shotguns. He is also a Texas DPS School Safety Certification Instructor, contributing to enhanced safety measures in schools across the state.
“Ranger Brad Oliver has a distinguished history of service and leadership that has earned him the respect of the law enforcement community and the citizens of Grayson County,”
Grayson County Sheriff Tony Bennie said. “We are proud to welcome him as our next Chief Deputy, and we look forward to his continued commitment to serving this community.”
Ranger Oliver is widely recognized and respected not only for his law enforcement achievements but also for his dedication to the people of Grayson County. His leadership and experience will be invaluable as he assumes this new role.
