Chief Jon Belmar was appointed to the position of Chief of Police on January 31, 2014 by the St. Louis County Board of Police Commissioners. 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 was raised in North St. Louis County and currently resides in West St. Louis County with his wife and their two children.

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. 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 is an active member of both the Affton and South County Chambers of Commerce. In addition, he was appointed to the St. Louis County Domestic and Family Violence Council in 2000, and has been a member of that council's Executive Board since 2001.

Chief Belmar holds a 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 the 228th Session of the FBI National Academy in 2007. He has received 48 awards and letters of appreciation.
