Clinical Associate Professor Ong Chiou Li helped transform diagnostic imaging at KK Women's and Children's Hospital, expanding it into a comprehensive modern service. Her work in women's and foetal imaging, education and philanthropy continues to improve patient care while nurturing future generations of radiologists.

A legacy that reaches far beyond medicine

Though their careers span different specialties, the impact of these three Emeritus Consultants shares a common thread: building something that lasts beyond their own practice. Professor Cheng advanced modern urology while shaping new institutions and mentoring future clinicians. Associate Professor Ling strengthened infection prevention systems that continue protecting communities in Singapore and across the region. Clinical Associate Professor Ong transformed diagnostic imaging while investing in education and the next generation of healthcare professionals.

Together, their contributions demonstrate that the practice of medicine extends far beyond treating illness. It is about building stronger healthcare systems, advancing knowledge, preventing disease and creating opportunities for those who follow. In honouring these three exceptional leaders, SingHealth celebrates not only a lifetime of medical excellence, but an enduring commitment to improving lives for generations to come.
