Celeste Dong, RDH



After graduating from Davis, I found my interest in Dentistry and became a hygienist. One of the best decisions ever! I love my job. Seeing a patient with cleaning teeth and beautiful smile after each appointment is satisfying; seeing a patient's improvement on brushing and flossing is very rewarding. I love working at Dr. Thai's office. With his supervision, I can practice dental hygiene with highest standard. I love my patients.  When I'm not at work, I'm busying taking care of my infant boy. He was born in June 2015. He has exceeded all the expected milestones, making me a proud mother. In my very limited spare time, I like to play boardgames with my husband and friends, go hiking in the redwoods, try new recipies and restaurants. If you are a foodie like me, please come to the office, I'll show you how to take care of your teeth to eat anything at any age!
