Meet the team


We stand on the shoulders of giants

The late founder Loy Khai Kow was the pioneer during Colonial Singapore. He passed the exams (under the Registration of Dentist Ordinance) in 1950 and started his practice in Jalan Besar.


He served actively in the Singapore Chinese Dentist's Association. To date, we still hear patients sing praises of how gentle he was.

The baton was handed over to the late Loy Shiow Wen, who was especially skilled in dental prosthetics. Patients still say they cannot bear to throw away 20-30 year old dentures made by these kind and skilled practitioners.
