By County Charter, the Chief of Police is responsible for the law enforcement duties of the Sheriff. St. Louis County is unique in the U.S., as it does not have an elected sheriff. Chief Belmar has served the agency since 1986. The St. Louis County Police Department serves a population of over one million and a geographical area of more than 500 square miles. Current agency strength is nearly 1,100 and it has a budget of more than $113 million.

Chief Belmar began his career in the Affton Southwest Precinct in 1986 as a patrolman. He also served in the South County Precinct and the Tactical Operations Unit before his promotion to Sergeant in 1995. As a Sergeant he served in the West County Precinct as a watch supervisor until selected to run the Department's Arson and Explosives Unit in 1996. In 1998 he was promoted to Lieutenant and remained within the Division of Criminal Investigation as the commander of the Bureau of Crimes Against Persons. He remained in that position until his promotion to Captain in 2004 at which time he was assigned as the Commander of the Affton Southwest Precinct and later as a Captain in Special Operations. He was promoted to the rank of Lt. Colonel in July 2013 and assigned the position of Commanding Officer of the Division of Special Operations.

Chief Belmar was appointed to the boards of Medal of Valor, S.T.A.R.R.S., and Backstoppers.  He is also a member of the International Association of Chiefs of Police, FBI National Academy Associates, N.O.B.L.E., National Tactical Officers Association, and the NAACP.

Chief Belmar earned a bachelor's degree in Criminology from Arkansas State University, and attended the FBI's Hazardous Device School at Redstone Arsenal, Alabama, where he was certified as a bomb technician in 1997. He attended the 228th Session of the FBI National Academy in 2007, the 56th session of the Senior Management Institute for Police in 2014, and the 38th session of the FBI National Executive Institute in 2015.
