Organization & Leadership
Who We are
At the Waldorf School of San Diego, we believe that the process of how we work together is as important as what we learn in the life of a school community. Because our organization is not hierarchical, governance primarily depends on healthy interpersonal and intergroup relationships. We strive to promote healthy relationships, so it is essential to understand collectively, our mission, vision, values, and goals as a school community.
We intentionally embrace shared, collaborative governance not only because it is effective, but also because it helps people and communities to grow. We invite every member of our school community to join the conversation by reflecting on this document and offering any ideas, comments, or other responses that you wish to provide. Please be open to engaging in one of the avenues of volunteering (parent association, committees, subcommittees, and the like) that we have mapped out together.
The Leadership Council is comprised of the Administrator, Rachel Davis, a Board representative, Rozzi Hafner, and a Pedagogical representative, Bonnie Holden, and concerns itself with the day-to-day decision making needs of the school that require timely input from all spheres. The three governing entities assume distinct governance responsibilities and strive for consensus on major policy decisions. This system of shared governance supports the development of a strong and healthy community from which students learn and grow. The Leadership Council is also responsible for monitoring progress of the Strategic Plan work delegated to the various spheres of the school. Overall, the Leadership Council will work to continually improve school-wide governance.
The Pedagogical Group (PG) is a group of faculty and staff, which serves as the governing body of the school’s pedagogy. It concerns itself with pedagogical research and study as well as assuming responsibility for the pedagogical well-being of the school. They meet on a regular basis to ensure they are providing guidance to the faculty as a whole.
Meet the Board
Within the collaborative leadership model, the Board of Trustees is responsible for the legal and financial health of the school. This means that the Board is striving to be a visionary, forward-thinking leadership body, tasked with the ongoing work of creating a Strategic Plan, cultivating a culture of openness in our community, and deepening their collective understanding of Waldorf schools and pedagogy and of Board best practices.

Over the years, she has spent time taking them ice skating, roller skating, on hikes, camping trips, to the mountains to experience snow, dozens of beach days and many other adventures.

As a member of the school community in Brazil, Ricardo had the opportunity to be a class representative, and member of both the Parent Association and the Finance Committee. At WSSD, Ricardo joined the Finance Committee and Tuition Adjustment Committee during the 2022-2023 school year.
The opportunity to live in multiple countries, experience different cultures and work in very diverse roles has enabled Ricardo to fully acknowledge the beauty and challenges of a diverse school community such as the one we have at WSSD. Ricardo truly believes that the collective capability of the WSSD community is spectacular, but the realization of its potential can only be achieved through the empathetic collaboration amongst its members with a dash of technical guidance.
