Declan Sullivan, M.P.A., came to the world of active bystandership through his experience as a Senior Program Associate at Georgetown University’s Center for Innovations in Community Safety. In 2021, Declan served as part of the leadership team for Project ABLE (Active Bystandership for Law Enforcement). Declan supervised all ABLE training operations, oversaw the agency application process, and led ABLE’s statewide initiatives in Washington, Colorado, and Utah.

During his time at ABLE, Declan was critical in allowing the expansion of the program to hundreds of police departments all over the United States and Canada. Thanks largely to Declan’s efficient and inspiring leadership, ABLE’s list of agencies grew from a small number of agencies to more than 300 police departments in three short years. In its early years, ABLE was understaffed, requiring Declan to play multiple positions at the same time. He brought outstanding administrative skills, deep respect for law enforcement, and empathy for police officers and the communities they serve and protect.
