MPH, CHE, NEMAA

Aaron D. Marshall is a senior emergency management, crisis response, and humanitarian operations executive with more than 15 years of experience leading complex, high-consequence operations across the United States and internationally. His career spans catastrophic disasters, national special security events, public health emergencies, and humanitarian crises—operating at the intersection of life saving measures, life sustaining activities, policy execution, and executive decision-making.

Aaron currently serves as an Incident Management Assistance Team (IMAT) Lead – Select (pending appointment by the Secretary of Homeland Security) and concurrently as an Operations Section Chief / Branch Director for Emergency Services, Mass Care, and Air Operations with FEMA’s Region 4 Regional IMAT #2. In these roles, he integrates federal, state, tribal, local, nongovernmental, and private-sector capabilities to deliver lifesaving and life-sustaining outcomes, translating strategic intent into action under intense time pressure, political scrutiny, ambiguity and adversity.

Across his career, Aaron has:

  • Supported most senior government leaders—including the White House, National Security Council, and Congressional leadership—with clear, decision-focused support during rapidly evolving crises

  • Held operational responsibility across some of the most disaster-prone regions of the United States, supporting jurisdictions with more than 2,600 miles of coastline and over 30 million residents

  • Led and coordinated thousands of responders under Unified Command

  • Directed Urban Search & Rescue, firefighting, public health, law enforcement, hazardous materials response, mass evacuation, sheltering, aviation, and emergency medical operations

  • Operated autonomously in austere, high-risk, high-velocity environments where judgment, trust, and clarity are essential

Prior to FEMA, Aaron served as a federal law-enforcement emergency manager with the U.S. Capitol Police, supporting National Special Security Events, demonstrations, CBRNE preparedness, and continuity of government operations within the National Capital Region.

Earlier in his career, he developed deep field credibility as a wildland firefighter, emergency medical provider, and all-hazards incident commander, deploying globally—experience that continues to shape a leadership philosophy grounded in compassion, service, and respect for those working under the most demanding conditions.

Aaron’s lifelong commitment is to alleviate suffering, restore hope, instill competence and confidence, wherever he may be.
