Who are we?

Guiding caregivers to grow in understanding their children so as to create supportive environments through Montessori philosophy and education.

Open Doors Montessori aspires to make Montessori education and philosophy accessible to families at home. We hope to journey with parents, caregivers and educators in the fulfilling and challenging process of raising children. Whether you are a new mum overwhelmed in the adventure of parenthood or an experienced educator confused by inconsistencies in a child’s development, we are here to help through Montessori observation techniques and to assist you in learning skills to follow the child’s needs.

Working with children from birth to 6 years of age, we will assist in setting up routines and spaces with an understanding of the child’s needs and psychology at this young and crucial age. Our pedagogy may focus on the child, but we will impart practical skills to parents and educators to help them as they grow with their children.
