The Deputies and Security Officers of the Security Department play a crucial role in delivering day-to-day services across all facilities owned or leased by the Health & Hospital Corporation of Marion County (HHC) and the Marion County Public Health Department(MCPHD). Security personnel also extend their services to cover events supported or hosted by HHC/MCPHD. These events include mass vaccination clinics, health fairs, classes for the public, special functions for employees and many others.

The Security Department also serves as an integral and proactive participant in the comprehensive public health emergency preparedness program of Marion County. Within this framework, the Director of Security serves as the coordinator for the security efforts. Several members of the Security Department also have designated roles at specific sites in the event of a public health crisis or disaster.
