I’m so pleased by the prompt action at Children’s Emergency. From the moment I arrived, the staffs were so attentive, compassionate in helping my son. Special thanks for Dr Shona & Dr Ong SY and their teams for their exceptional care. Their professionalism made me feel comfortable. The nursing staff also deserves recognition for their kindness and attentiveness as well, they checked in regularly every two hours. Overall, I highly recommend Sunway Medical Center, especially the children department to anyone seeking quality medical care.

Always see Dr. Ong Sik Yong for my child's follow-up appointments, and also Dr. Nazrul Nezham for treatment or IBD-related cases for my child. They are very professional specialists. So, for parents looking for specialists for their children, please see these two doctors. Their explanations are very clear and the treatment provided is very satisfactory.
