How things work at Green Meadow

Our Organization

Green Meadow Waldorf School is administered by various individuals and groups, all contributing to the legal, financial, pedagogical, social, and physical well-being of the school. These people include the members of the Collegium Committee and Collegium, the Administrator and the Director of Operations, members of the GMWS Advisory Board, the faculty, the staff, parent leadership, and the parent body. This unique way of working has two important impacts on everyone involved in the life of the school, including the students. Primarily, those making the decisions about the school are the ones in the school. This provides for immediate, inclusive, and meaningful decision-making from within. Secondly, it lays the foundation for a thriving community life, which requires those involved to work together for a common purpose.
