About the Middlesex Sheriff’s Office

The Middlesex Sheriff’s Office, established in 1692, is one of the oldest law enforcement agencies in the United States. Entrusted with full law enforcement capabilities, the Middlesex Sheriff’s Office provides care, custody and control of both sentenced inmates and pre-trial detainees. These functions are carried out at the Middlesex House of Correction in Billerica and the Middlesex Jail in Cambridge. Additionally, the Middlesex Sheriff’s Office operates the Sheriff’s Office of Civil Process, the Cambridge and Lowell Community Counseling Centers and numerous community service and crime prevention programs.

There are 800 men and women who perform the daily activities at the Middlesex Sheriff’s Office. These hardworking officers are responsible for the well-being of, on average, more than 1,400 individuals housed within our facilities.

Dedication to public safety does not stop at the walls of the institutions. The Middlesex Sheriff’s Office makes available to the 54 cities and towns of Middlesex County any and all resources that may enhance public safety. We have forged partnerships with local, state and federal authorities to organize and ensure these resources are available whenever and wherever they are needed.
