Corporate Philanthropy

The spirit of philanthropy is deeply embedded in the culture of Ong& Ong. Education is a key component of Ong&Ong"s philanthropic effort, centering at the architectural society. The Ong&Ong Travelling Fellowship was first established in 1997 with the objective to allow gifted graduates the opportunity to pursue the knowledge and experience of the built environment through independent travel. In 2000, the Ong Siew May Professorship was set up to pave the way for architects worldwide to lecture at the National University of Singapore"s Department of Architecture.
