MOUNT PLEASANT, S.C.

Chief Arnold brings 25 years of experience in law enforcement, all spent with the Mount Pleasant Police Department. 

“Mark possesses the education, experience, and skills to serve successfully as Mount Pleasant’s police chief.  He understands our community and shares Town Council’s belief in the importance of maintaining a safe community,” said Mount Pleasant Town Administrator Eric DeMoura.

From 2003 through 2013, over the course of his tenure as sergeant, Chief Arnold acquired a large breadth of knowledge as supervisor of the Criminal Investigations Bureau and Patrol Division. He held the position of Career Development Supervisor where he developed and conducted training programs consistent with national, state, and departmental standards. More recently, Chief Arnold served as the accreditation manager for the Police Department, which is nationally accredited through the Commission on Accreditation for Law Enforcement Agencies. 

Chief Arnold was promoted to Lieutenant in 2013 and supervised the Office of Professional Standards. A year later, he was promoted to the rank of Captain and managed the Field Operations Bureau and the Support Services Bureau. He was promoted to Deputy Chief in July 2020.
