Dr Ong started her medical career in 1985 in various public hospitals. She then joined a private group practice before leaving for postgraduate studies in dermatology in London. In 1994, she opened Maple Clinic in Tampines, which started as a general practice clinic but soon became a family practice dermatology clinic seeing mostly patients with skin conditions. In line with emerging trends among dermatologists in the United States in the 1990s, Dr Ong was among the first in Singapore to seek to enhance treatment outcomes by complementing prescription medicines and medical procedures with medical skincare products. The suite of skincare products, which Dr Ong jointly developed with overseas laboratories and manufacturers, grew over the years to more than 100 items today. While treatment for skin issues remained the mainstay at Maple Clinic, services like aesthetic injectables and lasers were added over time. Dr Ong has been instrumental in embracing new and effective treatment technologies for our clinics, pioneering the adoption of such machines as PicoSure, MiraDry, Isolaz and Cutera Xeo in Singapore.
