And he's been thrown right in, making sure the county is ready if Hurricane Storm Dolly should make a sudden turn toward Houston.
"During a non-event, when the skies are blue and everyone is enjoying the Houston area, we want to make sure that they know that we're doing our jobs in the planning processes so that when this event like this occurs, we're not reacting to it. It's a natural transition for us."
Sloan started with Harris County in 2002. He was appointed by then County Judge Robert Eckels.
He's worked in a variety of disaster situations, from the Fire Marshall's office to HAZMAT response. He was also the volunteer coordinator at the Astrodome for Hurricane Katrina, where he was responsible for managing 60,000 volunteers.
He says he's pleased with how things are running at the county.
"Being in charge so to speak, it's pretty routine because we are fortunate and resource-rich and we have a lot of people that have been through numerous events here, from flooding events, from chemical industry events, Tropical Storm Allison and the hurricanes — they know their jobs."
