Katherine Pasternak

B.F.A., B.ed.

Welcome to Autumn Hill Academy. My name is Katherine Pasternak. In 1996 I founded Autumn Hill Academy. My passion and interest in early childhood education began at the Faculty of Education at York University. Throughout the course of those years, while researching many different theories and teaching practices, I realized the importance of education for young children. My search led to two significant methods of education – the Montessori Method and the Reggio Emilia Project Approach. Both pedagogies are considered leaders in the field. My vision was to adopt successful, meaningful methods of early childhood education and surround myself with a team of educators and support staff who share my vision. I am proud to say that Autumn Hill continues to be a school that offers an advanced, enriched, well-balanced program for children ages 18 months to Grade 3. I invite you to visit Autumn Hill as we continue to “Promote Thinking and Excite the Imagination”.
