Boone County Office of Emergency Management head to resign

Terry Cassil, the head of Boone County’s Office of Emergency Management, plans to resign in December.

Cassil told ABC 17 News that his last day with the county will be Dec. 1. He said he looks forward to spending more time with his family and enjoying himself after several decades working in the public sector.

Cassil ran the county’s OEM since 2015. He oversaw the transition of the 911 Center from the city of Columbia to the county’s jurisdiction in that time.

Presiding Commissioner Dan Atwill said he was sad to see Cassil go. Atwill said the commission would begin searching for a new OEM director soon.

Cassil came to Boone County from the Missouri State Emergency Management Agency, where he was chief operating officer. He also worked for 21 years at the Columbia Fire Department, where he retired as an assistant chief in March 2014. Cassil also deployed with Missouri Task Force 1 in the wake of Hurricane Harvey.
