Special events—concerts, 5Ks, parades, and large public gatherings—place unique demands on emergency services. While many events are routine and uneventful, they can quickly become disorganized and stretch resources beyond normal operations. This session explores how one community transformed its approach to special event planning by building a dedicated, cross-functional team that integrates public safety, operations, and community stakeholders from the earliest planning stages.
EMS Deputy Chief Bill Ackley, alongside Police Captain Doug Deiso, will discuss how their team was developed and the key elements that brought it all together—from standardized planning protocols and risk assessment frameworks to interagency coordination practices designed specifically for special event environments. Attendees will learn how these processes strengthened not only event-specific outcomes, but also enhanced day-to-day operational readiness.
Participants will leave with practical tools and lessons learned for building their own integrated special event planning teams, along with strategies for translating event-planning discipline into lasting improvements in daily operations and community resilience.
