I could not be happier having my son at Kell and look forward to my daughter attending in a year. We are so fortunate to have this gem of a school in Cobb County. The administration, teachers, extra curricular opportunities and overall community are fantastic. The communication is excellent. They follow through on what they say they are going to do. Kell provides our students the tools and experiences they need to be successful and achieve college readiness in a very safe and nurturing environment. I have been particularly impressed with the (marching) band program. Close Quote

Great change to the school this year! Dr. Giles has brought back school spirit, community, and pride to the school. Teachers and students feel valued again! The new LASSO structure is awesome and has helped so many students academically already and is an incentive for all students. Proud to live here and have my students go there. Don't believe any previous bad comments about the school. It has all changed now! Close Quote
