Winnie Jamieson, First Grade Teacher

MA, Philosophy and Education, Columbia University Teacher's College; BA, Education & BA, Philosophy, Brooklyn College; NYS teaching license, Childhood Education, Grades 1-6; Waldorf Teacher Training, Sunbridge Institute (completion in 2014).

The year her Class of 2025 students were born, Winnie went back to school to follow a calling into education. She soon became interested in exploring the foundations and goals of education through a philosophical lens. While seeking to answer the question “What kind of education helps to create a happy and healthy human being?”, Winnie discovered Waldorf® Education.

She is excited to transition with her son into the Green Meadow Waldorf School community. This for them means more time in nature, painting, singing, and playing.

Ruth Olson, Third Grade Teacher

BA Psychology, McGill University Canada. ECE Montessori Teacher Certification, Canadian Montessori Academy. MEd., Waldorf Teacher Training, Antioch New England Graduate School.

Ruth began teaching very young, when she summoned up the smallest neighbors on her street, handed out the books and pencils, and her teaching career was off. Since then, Ruth has pursued her own love of learning through her undergraduate studies in Psychology at McGill and Simon Fraser Universities. She has received training as both a Montessori teacher and Waldorf educator. For Ruth, the main goal of teaching is to reflect the gifts each child innately carries, and to be joyful in her work. Waldorf education connects Ruth to what she loves best, including time in nature, making music, and being with children. Ruth lives with her husband, three children, two cats, and a big yellow dog in Chestnut Ridge.
