Chief Fallon was promoted in September 2014.
Born and raised in Somerville, Fallon joined the Somerville Police Department in 1998 as a patrolman. He rose through the ranks to sergeant, lieutenant, captain, and eventually deputy chief. His long list of accomplishments in the department is firmly rooted in the culture of evidence-based decision-making and community policing that grew from departmental reforms over the past decade. He aims to build upon these approaches, which have contributed to the significant drop in crime in Somerville by more than one-third since 2008.
