An EMT is assigned to the Boston Police Harbor Unit from mid spring though late fall.

Boston EMS maintains a fully staffed Special Operations Unit which includes a heavy duty rescue truck, two medium duty rescue trucks, a state-of-the-art MCI bus, support trailers, ATV's and a bike team for special events and major incidents.

In addition, several other specialized units provide logistical/technical support for Boston EMS operations, including a modern Dispatch Operations Center (staffed by EMTs) located in Boston Police Headquarters, the Training Division, a Community Initiatives Office and Administration & Finance office.

After 36 years of service with Boston EMS, Chief of Department Richard Serino retired in October 2009 to accept the position of Deputy Administrator of the Federal Emergency Management Agency (FEMA) after nomination and confirmation by the US Senate.

On January 25, 2010, Mayor Thomas Menino appointed Superintendent-in-Chief James Hooley, a 32 year veteran of Boston EMS as the new Chief of Department.
