History of Mildenhall Montessori

Mildenhall Montessori Schools is a family owned endeavour. The Schools’ owners, Brent Lisowski and Brenda Hebert, have been involved in Montessori education since 1978 when their eldest child, Anne (current Head of School), began attending High Park Gardens Montessori School. Both Brent and Brenda have had successful careers as senior partners at two of Canada’s major law firms, but the schools have been their pride and joy for the last 30 years. They have dedicated their efforts to ensuring that the Schools are providing a program that is optimal for the children, are flexible and responsive to parental requests, are staffed by highly qualified and experienced educators, and are sustainable for generations.

Follow the Child - Maria Montessori

Mission and Values

Mildenhall Montessori Schools are guided by an aspiration to prepare each child for the challenges and opportunities of life. From the carefully constructed environments to the mindful interactions of the teachers to the mixed age classrooms to the three year learning cycles, our schools focus on preparing our children academically, socially, and emotionally.

Our teachers trust that the child will achieve beyond any set standards if given the opportunity to do so. This education is founded on respect for every individual’s diversity, independence, and curiosity. The environment and skilled teachers support self-initiative and self-confidence through the development of critical thought, experimentation, and exploration. The guidance towards independence and self-discipline invites children from 2 to 12 years of age to actively participate in the world.

The result of the process from early years to middle school, is a well prepared, confident, independent, and thoughtful learner, who can excel not only in school but in life.

We hope you can get a feel for the Montessori method through our program information and the FAQ. There is endless information (and misinformation) available on the internet regarding Montessori.

The following sites have reliable information and can guide you further in your discovery of the Montessori method:

The Montessori Foundation - www.montessori.org
Canadian Council of Montessori Administrators - www.ccma.ca

Please don’t hesitate to call us about anything you wonder about. We’d love the chance to explain why we choose to educate our children in this way.

Our Faculty

Mildenhall Montessori Schools

Anne Smith, Ph.D.

Head of School

Our Head of School was one of the first students at High Park Montessori school when it began in a small Church on Runnymede Rd. She spent her lower elementary years happily climbing all the stairs to the top floor at 35 High Park Gardens. Dr Smith credits her experience in Montessori for the skills to adapt to multiple varying educational and professional environments, including the ability to persevere, the development of flexible learning styles, and an intrinsic motivation to learn. Now Anne’s own daughters are in the elementary program at the Mildenhall School, and Anne is bringing her experience as a clinical child psychologist, researcher, and educator to the steering of our schools.
