On August 22, 2012, Mr. Ryan Kosko joined the Columbia County Sheriff’s Office. In a swearing in ceremony, Sheriff Mark Hunter provided Mr. Kosko with the Oath of Office, officially making him a member of the Sheriff’s Office. The ceremony was attended by Mr. Kosko’s family as wel as his future co-workers. Deputy Ryan Kosko will be assigned to the Patrol Division and will enter an extensive training period. We would like to welcome Deputy Kosko to the Columbia County Sheriff’s Office family.
