City to hold swearing-in ceremony for new Police Chief David Terlemezian

posted on 10/3/2025

The City of Dover will formally swear in David Terlemezian as the city’s new Chief of Police during a public ceremony on Monday, Oct. 6, at 6 p.m. in the City Hall auditorium. The event will also recognize several promotions from within the Police Department.

Terlemezian succeeds Chief William N. Breault, who retired in September after nearly three decades of service to Dover, including the last seven years as chief.

Terlemezian has served with the Dover Police Department for nearly 30 years, beginning as a patrol officer in 1996. He quickly advanced through the ranks, serving as detective, sergeant, lieutenant, and captain before his appointment as chief. In his tenure, he has overseen investigations, training and accreditation, community outreach, grant administration, and financial management.

Terlemezian, a Dover resident, is a graduate of the University of New Hampshire and holds a master’s degree in criminal justice from Boston University. 

The swearing-in ceremony is open to the public.
