After 20 years of teaching science at South Central High School, Mr. Dereck Koester is closing an important chapter in his career. For the past two decades, he has inspired countless students from the same classroom, sharing his knowledge, dedication, and passion for science along the way. His impact on the school and community will not be forgotten, and he will be greatly missed by students and staff alike. We thank Mr. Koester for his years of service and wish him the very best wherever life takes him next!
