Montessori School will be a new preschool day and child care experience for your kid. Visit our website to learn more. Our elite program is for children ages 3 to 5 and who are potty trained (except for the Bambino /Toddler Program). Red Deer Montessori Preschool is a prepared class environment. Children are given group lessons as well as individual lessons thereby giving them the skills needed to complete their work as an individual as well as with a partner.
