His early years were spent gaining experience, learning the intricacies of law enforcement, and developing a foundation that would guide him throughout his career. In 1998, he took on a role at the Jefferson County Juvenile Detention Center, continuing his service to the community while broadening his understanding of public safety and juvenile justice.
In 2004, Harper returned to JCSO as a full-time deputy assigned to the Patrol Division, a role in which he demonstrated dedication, leadership, and an ability to handle complex challenges. Over the next decade, his career progressed steadily. In December 2007, he earned a promotion to Corporal while serving in Patrol, followed by his elevation to Sergeant in November 2012.
