Board of Trustees
As an independent, non-profit foundation, ISA is strategically guided by a Board of Trustees (the Board), a group of dedicated professional volunteers, providing legal oversight to the organisation.
The Board plays a central role in looking out for the long-term interests of the school. Approval of the school’s annual budget, salaries and capital expenditures are amongst a few of the board’s responsibilities. They are the stewards of the schools assets and, through defining the school’s mission, vision and philosophy, they serve as the architects of the school’s future.
The Board of Trustees for the 2023-2024 school year are:
