Michael A. McCormack, Sheriff
Michael A. McCormack was sworn in on January 6, 1999 as the 22nd Sheriff in the history of the County of Dukes County. He was re-elected in 2004 and again in 2010.

The County of Dukes County is comprised of Martha’s Vineyard, Nomans Island and the Elizabeth Islands; and includes the towns of Aquinnah, Chilmark, Edgartown, Gosnold, Oak Bluffs, Tisbury and West Tisbury. The year round population is approximately 17,000 and increases to over 100,000 during the tourist season.
Sheriff McCormack summered on Martha’s Vineyard in his youth and forty years ago brought his bride to Martha’s Vineyard to show her the island that he always loved. He became an officer for the Oak Bluffs Police Department before catching the attention of Sheriff Christopher S. Look, Jr., who hired him to work at the Jail and House of Correction. Sheriff McCormack worked his way through the ranks to become second in command of the department, Special Sheriff, a position he held for twelve years prior to his election as Sheriff.

As the county’s chief law enforcement officer, Sheriff McCormack is responsible for the administration and operation of the Jail & House of Correction, the regional police lock-up, the E 9-1-1 Communication Center (providing emergency dispatch to sixty-five public safety agencies, including all police, fire, and EMS services), the Community Corrections Center, the Drug Information Bureau (includes the DARE Program in all Island elementary schools), TRIAD (includes Project Lifesaver, File-of-Life, We’ve Got Your Number, and other prevention programs), the patrol of Joseph Sylvia State Beach, the Marine Division, and the Civil Process Division.

Sheriff McCormack is a member of the Martha’s Vineyard Chiefs of Police Association. He serves as President of the Association and, together with the island chiefs, has been awarded a COPS grant to create a central records management system (RMS) and a computer aided dispatch system (CAD) that has enhanced the delivery of law enforcement services to the citizens of Martha’s Vineyard.

Sheriff McCormack is a member of the Massachusetts Sheriffs’ Association. He served as its President in 2004 and 2005, after having served as its Vice-President in 2002 and 2003. He is currently the Chairman of the Sheriffs’ Information and Technology Committee and is working with the Commonwealth’s IT Division on the MIDNet Project (inmate information sharing with other law enforcement agencies) and the SIMS Project (inmate management).

Sheriff McCormack is active in the community. He serves on the Dukes County Personnel Board, the Board of Directors for the Martha’s Vineyard Arena and is President of the Endowment Fund for the MV Arena. He lives in the town of West Tisbury with his wife Mary Lee.
