Our Board
“An important key to the success of an international school is the quality and commitment of the Board of Trustees. I could not have been more impressed with the talent, enthusiasm, and dedication of the outstanding individuals on the Board of AIS. I have no doubts but that AIS will be a remarkable international school. And the fact that the school seeks to be accessible to all families makes it almost unique amongst international schools around the world.”
