Saskia Pothof, Farm Classroom
Saskia was born and raised in the Netherlands in a Waldorf family. After she completed her Masters Degree in Child Psychology, she worked for eight years in long-term foster care. An encounter with a dolphin in Spain sparked her interest in research on communication with wild dolphins, and in the following years she swam in many oceans with different species of dolphins. In 1993 Saskia moved to the United States to live with her husband and, when her daughter was pre-school age, was glad to discover the flourishing Waldorf community in this area. Saskia completed the Waldorf teacher training at the Center for Educational Renewal in the spring of 2002, and became our first grade teacher at Summerfield in the fall of that year. Saskia served as a class teacher at Summerfield for sixteen years, and after graduating her second class in June 2018, she shared her love for art, singing, and teaching as a specialty teacher in the grades in Lower School, and in Teacher Training.
Since 2019 Saskia can be found on the farm, working and learning along with the farm classroom, a group of students of mixed ages who thrive in an environment where they can be outside year round, working with their will and their hands on our beautiful biodynamic farm. Meaningful physical work, inspired by the daily and seasonal rhythms on the farm forms the foundation for building skill and confidence in their academic and artistic work. The farm class has become a community where we meet each other’s differences in learning and life style with interest. When the farm class sits down around the big table under the oak tree for a meal of vegetables that were planted, tended, harvest and prepared by the children, Saskia feels like a childhood dream has come true. Her daughter, Dawn, who was a student at Summerfield from Kindergarten through 12th grade, graduated from Summerfield High School in 2012.
