Bonnie Johnson

first GRADE ASSISTANT

Bonnie became acquainted with anthroposophy and Waldorf Education while managing a natural foods co-op just out of college. She later assisted in the Kindergarten at the Meadowbrook Waldorf School in Rhode Island. It was years later, when her eldest child graduated from Green Meadow and her youngest was ready to enter our First Grade, that Bonnie tired of living vicariously through her children's Waldorf Education and enrolled in Sunbridge College, completing the Foundation Studies and teacher training programs. She has also been an afternoon Early Childhood teacher at Green Meadow.

She also studied ceramics for two years in Italy and received a certificate of professionalism at the State Institute of Art in Faenza. 

Mellie became interested in Waldorf Education during her undergraduate studies, and then began the Teacher Training Program at Sunbridge Institute in 2014. She spent the 2014-15 school year assisting at GMWS. 


William Minehart

seventh GRADE TEACHER

BS, Environmental Studies, Bucknell University; MS Education, Elementary Waldorf Education, Antioch University of New England

William often finds himself reflecting on much of his youth in the woodlands of Pennsylvania. A lifelong love for birds and the outdoors led him to researching birds in the tropical rainforests of Australia and the Peruvian Amazon. While living in these places, he also began to explore ways to heal the relationship between humanity and the rest of the natural world. William discovered his passion for education through working in the mountains of Colorado and Washington, where he focused on creating positive experiences for youth in the wilderness. It was at one of these institutes that William met his wife and started a family.

William taught high school science for four years in a public high school in New Jersey and shared a classroom with his wife. He assisted at GMWS and took his current class in 2015-16.

Ruth Olson

sixth GRADE TEACHER

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

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: time in nature, making music, and being with children. Ruth lives with her husband, three children, two cats, and big yellow dog in Chestnut Ridge.
