S.K.
Our kids go to Dr. Shitabata. She is great! Very friendly staff. We don't ever have to wait. In fact, when we walk in, it's like the whole office has been waiting for us with charts and files in hand. Nobody leaves us to go anywhere until we say good bye. The kids get toys galore, so they're always excited to go to the dentist. It's off of Skypark and Madison (Near Hawthorne Blvd) We have Delta Dental. I don't know what other insurance they take.

You could also check with Dr. Timothy Quon. My husband and I go to him. He works with kids also. Really nice guy. I haven't met a hygenist I didn't like at his office. All very professional people, excellent cleaners, very friendly personalities. He's in the Torrance Memorial block of buildings. ###-###-####. 3440 Lomita Blvd, Ste 340.
Good luck finding a good dentist!
