The name of Mill Creek Middle School was chosen due to the school’s close proximity to Mill Creek and because the school is located at the intersection of Mill Creek Road and Arnold Mill Road. The wildcat, with its strong instinct for survival, expertise in the hunt, and fierce competiveness when challenged, has a history of a long and continued presence in Georgia. Therefore, the school mascot became the Wildcats because the school embodies the characteristics of such a clever and resilient animal. The school’s colors – garnet, gold, silver, and white – were chosen because of their distinct regal appearance.
Mill Creek Middle School, located on Arnold Mill Road, was constructed by the Cherokee County Board of Education in August of 2009. While the school was in construction, Little River Elementary graciously hosted the first MCMS 7th grade class of 350 students referred to as Little Mill Creek. In August of 2009, the newly constructed Mill Creek Middle School opened its doors to 650 7th and 8th graders. That same year, the school also hosted around 300 9th grade students awaiting the completion of the new River Ridge High School. In August of 2010, Mill Creek was fully launched with approximately 1150 6th, 7th, and 8th graders.
