MAVIS KHOO-OEI

WHY HER? With sister Elizabeth Khoo, Mavis is a trustee of her late father Khoo Teck Puat’s estate. Once Singapore’s richest man, the Khoo patriarch made his fortune in banking, hospitality and real estate. In the past decade, the family’s charitable arm, the Khoo Teck Puat Foundation, and the estate of the late Khoo Teck Puat have jointly donated more than S$360 million (about US$260M) to various causes, including S$100 million to build the Khoo Teck Puat Hospital, S$80 million to fund medical research at the DUKE-NUS Medical School and S$50 million to build the Khoo Teck Puat—national University Children’s Medical Institute at the National University Hospital, which is nearing completion.
