A longtime employee of the Tarrant County Sheriff’s Department who started his career as a jailer was promoted Monday to chief of the jails.

Alan Dennis, 54, who joined the department in 1992, was promoted to executive chief deputy of confinement.

Dennis succeeds Bob Knowles, a well-liked chief jailer who died in January. At the time of his death, Knowles was praised as “one of the great jail commanders” by Sheriff Dee Anderson.

“Executive Chief Dennis will certainly honor and retain all he has learned from Chief Knowles, but also has bright and progressive ideas of his own to lead the agency into the future,” Anderson said in a statement.

Since 2007 as a chief deputy, Dennis has overseen five jails, 940 employees and thousands of inmates.

He rose through the ranks from jailer to sergeant and lieutenant in the sheriff’s special operations command. He has worked in criminal investigations, internal affairs and in a task force associated with the federal Drug Enforcement Administration.
