Marc Sullivan

Senior Program Director

Marc M. Sullivan is a 25 year veteran of the US Army, with continued service in the public sector leading emergency management response operations. He has a proven track record of excellence in volatile and complex environments, particularly in operational planning and execution.

Marc spent several years as the Chief of Operations for the Illinois Emergency Management Agency & Office of Homeland Security expediting large-scale responses including mass casualty/active shooter, chemical plant explosions and multi-alarm fires, flood related evacuations, and lethal tornadoes. Marc also led the state’s operational response in Chicago during the 2022 surge of asylum seekers from the southwest border. Mr. Sullivan’s development of a FEMA National Qualification System (NQS) compliant All Hazards Incident Management Team (AHIMT) resulted in enhanced response capability able to respond nationwide for emergency management and disaster relief operations.

Marc was the senior military officer in the Defense Advanced Research Project Agency (DARPA) initiative for development of the Rapid Attack Detection, Isolation, and Characterization Systems (RADICS) tool. This collaboration with the Department of Energy (DOE) and electric utility providers led to the construction of a response framework during cyber-attack(s) on electrical grid critical infrastructure. He went on to revise the Illinois Threat Hazard Identification Risk Assessment (THIRA) to reflect the impacts of cyber-attacks on critical infrastructure and cascading effects across the state.

Focusing on adaptive and resilient approaches, Marc guides organizations to pro-actively mitigate risks, enhance readiness, and respond effectively to emergent situations, ensuring they can navigate crises with strength and confidence.
