Criminal Investigation Division
CID Commander Glenn Grannan

Commander Glenn Grannan began his career in law enforcement when he joined the Jefferson Parish Sheriff’s Office (JPSO) in 1975. He was selected to receive specialized training and became an undercover agent as member of the JPSO Narcotics Division.  Grannan spent the next two and half years in the Narcotics Division working undercover.   As a result of his work, he received two (2) Distinguished Service Awards and the Veterans of Foreign Wars Outstanding Contribution Award for 1977. Grannan remains recognized today as one of the most successful agents to work undercover narcotics operations in the Metropolitan New Orleans area.  Grannan spent the next two years serving as a patrol deputy with the JPSO Uniform Patrol Division.
Grannan left the JPSO when he was recruited by the Union Pacific Railroad Police Department (UPRRPD).    He enjoyed an extremely rewarding career with the UPRRPD and was given opportunities he could have never experienced anywhere else in law enforcement. With the UPRRPD, Grannan held the positions of Special Agent, K9 Handler, Special in Charge, Commander of an Executive Protection Unit, Commander of The Narcotics Unit and Deputy Chief.  His career with the UPRRPD lasted over 18 years during which time he received The Chairman’s Outstanding Achievement Award four (4) times and was recognized by the FBI, DEA and Fort Bragg Special Operations for outstanding contributions.
In 1997, Grannan left the UPRRPD to pursue his private interest in business and became a successful businessman on the MS coast as an owner and operator of Pelican Cove Marina PC, MS.  In 2005 Hurricane Katrina destroyed the business and his home.  Grannan began Storm Surge Marine in Bay St. Louis where he and his partner developed and build state of the art constructed recreational boats. 
Throughout this time period between 2006 and 2011 Grannan maintained his ties with LE working as a consultant and a professional investigator.
Grannan received his formal education from Louisiana State University, Dominican College, Loyola University and Tulane University.  He has amassed nearly a thousand hours of professional education including executive level management as a graduate of The Center for Creative Leadership in Greensboro, NC, The Drug Enforcement Administration’s Instruction in Narcotics and Dangerous Drug Investigation accredited by Wichita State University, a of number corporate leadership conferences and hours of LE training both basic and specialized such as critical incident intervention, hostage negotiations and advanced interview skills.         
Grannan was a part of Sheriff Adam’s transition team after the Sheriff’s election wherein Sheriff Adam requested Grannan to assume command of the Criminal Investigation Division.
