Glaiser was previously appointed interim chief in October 2021 following the departure of former Chief Robert Isbell. Isbell left the city at that time to serve as fire chief in Stephenville.
According the city, Glaiser has served the city of Round Rock's Fire Department in every position with a 27-year career in the department preceding his appointment.
"He's earned everything that he's about to have bestowed upon him," City Manager Laurie Hadley said. "I can't think of anyone better to lead this department into the future."
In his time with the RRFD, Glaiser acted as the project lead for the city's Public Safety Training Center, which was completed in 2018. He has earned both a bachelor’s degree in fire science from Columbia Southern University and a master’s degree in public administration from Sam Houston State University.
