Our family has been treated by Dr. Ong for about 10 years. He is a VERY gentle dentist, and has wonderful staff. We have Delta Dental and so far, nearly every procedure has been completely covered by the insurance. The office takes care of the billing, etc.
We have had fillings, crowns, and then regular maintenance for kids and adults in our famliy. When we moved about 20 miles away, we still kept him as our dentist because I think we would be hard-pressed to find a new dentist like him!!
