Two longtime members of the Fairfax County Fire and Rescue Department have been selected to become deputy chiefs in the agency.

Daniel Gray is being promoted to the role of deputy chief for safety and personnel services. In the position, he will handle health and safety, recruitment and personnel for the 1,600-member department.

"It's a great opportunity," Gray said.

Gray has been working in public safety in Fairfax County for about 30 years and has served as a battalion chief in the organization's safety and personnel division since 2006. He said his goals in his new position are "to keep firefighters as healthy and as safe as possible" and to increase awareness of departmental policies in order to avoid human resources issues.

Additionally, Robert Zoldos is becoming a deputy chief for the Fire and Rescue Department's Operations Bureau. In the new job, he will be in charge of one of the three shifts of firefighters and medics who respond to emergencies, overseeing about 350 people in Fairfax County.

"It's actually a huge task, and I'm truly looking forward to it," said Zoldos, who has been with the department for almost 19 years.

Both Zoldos' and Gray's promotions are effective May 4.
