Coryell County sheriff's office promotes four members, reshuffles leadership roles

The Coryell County Sheriff’s Office promoted four members on July 16, moving Sgt. Tony Dingianni up to lieutenant and putting him in charge of the Operations Division. The reshuffle reaches beyond titles inside the courthouse and jail complex in Gatesville, because it changes who supervises patrol coverage, shift management and the county’s day-to-day response to calls.

The office also promoted Cpl. Anthony Martinez to sergeant, and deputy Alanna Sweeney was among the members elevated in the department’s public announcement. The sheriff’s office framed the change as a promotions announcement and publicly congratulated the members, signaling that the leadership shift was meant to strengthen the agency from within rather than mark a break in direction.

For Coryell County, those promotions matter because the sheriff’s office covers much more than routine patrol. Its work includes rural response across the county, jail operations, criminal investigations and coordination with police departments in Gatesville, Copperas Cove and Evant, along with outside partners such as the Texas Department of Public Safety. When experienced employees move into supervisory posts, the department keeps people who already know the county’s roads, repeat trouble spots, courthouse procedures and jail routines.

That continuity can shape how quickly deputies are deployed, how supervisors cover busy shifts and how the office prepares for seasonal pressures. In Coryell County, those pressures include traffic enforcement, heat-related emergencies, flood response and wildfire risk, all of which can strain a small department if leadership is unsettled. A promotion from within can also help with retention in a field where turnover remains a common challenge for smaller counties.

The sheriff’s office says its mission is to improve quality of life through professional services and community partnerships. Its vision is to be recognized as the regional leader among law-enforcement agencies by using policing technologies, keeping professional employees and showing innovation and operational flexibility. The latest promotions fit that approach by elevating staff who already know the county and the office’s routines, while giving the department a clearer supervisory bench for the months ahead.
