CMS is affiliated with both the American Montessori Society and the International Montessori Council. Our degreed and certified teachers “follow the child” by utilizing Montessori methods, materials and philosophy to create a unique learning experience for each of our students. Our small, closely knit community is a nurturing place to learn and grow. Our Pre-Primary Program is licensed by the Kentucky Cabinet for Health and Family Services. The expansion of our program was mentored by Xavier University. We are conveniently located near NKU and downtown Cincinnati.
