Our Doctors
Dr Ong Fung Chin
MBBS (NUS, Singapore), Dip Derm (King’s College, London), GDMH (NUS, Singapore)
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.
Dr Ong obtained her degrees of Bachelor of Medicine and Bachelor of Surgery from the National University of Singapore in 1985. She subsequently enrolled in the United Medical and Dental Schools of Guy’s and St Thomas’ Hospitals (now part of King’s College, London), where she received a postgraduate Diploma in Dermatology in 1992. She also obtained a Graduate Diploma in Mental Health from the National University of Singapore in 2021.

Dr Handry Gumanti

Dr Melvin Tan

With over a decade of experience in Head and Neck surgery (Otorhinolaryngology) and the completion of specialist training, Dr Tan brings extensive surgical expertise and a deep understanding of facial anatomy to his practice. This background equips him with the precision and technical skills required to assess and enhance the delicate structures of the face with confidence and care.
Alongside his surgical career, he has always nurtured a keen interest in aesthetic medicine. This passion has guided his transition to aesthetic work, where he focuses on helping patients achieve their ideal appearance in a safe, thoughtful and personalised manner. He is particularly familiar with the nuances of the Asian aesthetic face and the principles that contribute to natural, harmonious results.
He believes that every patient’s journey is unique. His approach is grounded in listening attentively to patients’ needs, understanding their goals and exploring with them what works best for their individual features. Whether through subtle refinements or more transformative changes, his priority is to ensure that patients feel comfortable, supported and confident through the process.
Competence in techniques, combined with patience and empathy, defines his practice. He is committed to delivering results that not only enhance appearance but also respect the natural balance of the face, helping patients look and feel their best.
Dr Tan has been practising medicine since 2006, after graduating from the National University of Singapore with an MBBS degree. In 2012, he was admitted as a Member of the Royal College of Surgeons of Edinburgh, and in 2021 he successfully completed his specialist training. Beyond clinical practice, Dr Tan has contributed to medical education as a Clinical Tutor to undergraduate students at both the Lee Kong Chian School of Medicine, NTU and the Yong Loo Lin School of Medicine, NUS. These experiences reflect not only his commitment to advancing knowledge, but also the trust placed in him to guide the next generation of doctors. Today, Dr Tan brings this depth of training, teaching and patient care to private practice, where he dedicates himself fully to the art and science of aesthetic medicine.
