  • Dr KT Ong is indeed a doctor/surgeon who is true to his calling. It is not easy to get a doctor who is not only very professional in his job yet at the same time has a very caring and kind heart. My mom who is in her early 80s, had had her first major operation under the skilful hands of this dear surgeon and his team of support staff, was very much encouraged and comforted by him. Dr Ong took care to explain to my mom her condition and what was to be done etc....in Hokkien. My family and I would like to say a " big Thank You" to Dr Ong and we really appreciate your kindness towards our mom.

  • I delayed my haemorrhoidectomy for more than 10 years because I was convinced (by people around me) that the post-surgery pain would kill me and there are many risks/complications involved. Dr Ong has proved them all wrong with his magic hands. There was no pain at all. So I highly recommend this doctor to anyone who wants to remove anything.

  • Dr Ong Kee Thiam is a highly skilled & experienced surgeon in thyroid surgery. His diagnosis of thyroid cancer & proposed surgical procedure is world class. I came out of the operating theater with minimal discomfort & no complication. At the same time, SDMC SJ lives up to its gold accreditation in terms of state of the art facilities & quality service.

  • Really impressed with Dr Ong's way of handling my nuisance abscess. Rather being thrust upon decisions, we managed to really discuss it, seeking the best way/option to overcome my trouble. I was fully briefed and made to understand my problem and went through the whole process confidently. Thank you.
