Class Teachers
Arelly Sanchez-Shackett, Class One
Arelly Sanchez-Shackett was born and raised in Mexico City. Her family originates from Oaxaca, the region of the Zapotec indigenous communities–a heritage she cherishes deeply. She attended college at Iberoamericana University in Mexico City, completing a Bachelor’s Degree in Biomedical Engineering. After graduating, she moved to the Netherlands where she learned Dutch in order to attend Leiden University and obtained a Master’s Degree in Cultural Anthropology and Sociology. In her longing to support people more directly, especially people with special needs, she embarked on a work/study path in social work and graduated from The Hague University of Applied Science with a Bachelor’s Degree in Social Work. She worked in Rotterdam for many years in this field and loved it! After leaving the Netherlands, she moved to California to start a family with her husband. When their son was born, Arelly, as many other inspired Waldorf parents, decided to enroll in the Waldorf Teacher Training offered by the Bay Area Center for Waldorf Teacher Training, graduating in 2022.
Besides her regular work and study paths, Arelly has been involved in several projects supporting initiatives that promote spiritual or inner growth. She has been a meditation teacher and guide, director of a meditation center, and program organizer for weekend retreats and events. She is currently helping organize the Bay Area Choir of Uncovering the Voice and finds that supporting initiatives that bring inner growth and joy has always felt intrinsically rewarding to her. Arelly is very excited and honored to be joining Summerfield Waldorf School as the rising 1st grade teacher. Her son, Tomás, will join Summerfield too, in the 2nd grade class.

Meaningful physical work, inspired by the daily and seasonal rhythms on the farm formed the foundation for building skill and confidence in their academic and artistic work.
