Pediatric Dentist in MetLife Network Needed

We've been taking our son to see the same adult dentist that we do and it has worked really well so far. He has no fear or anxiety about going to the dentist and I really like the business-like, matter-of-fact approach. They never acted like there might be an issue with going to the dentist so he's never had an issue with going to the dentist. It probably helps that I love getting my teeth cleaned and look forward to our appointments.

Unfortunately my dentist is a general dentist and seems to know very little about dental issues specific to kids. I asked some questions about an issue that's been worrying me and she couldn't answer them. In fact, she wouldn't have even known that there was an issue until I brought it up. I think that we need to switch him to a dentist that knows about issues specific to children (permanent teeth, orthodontists, etc.). We have MetLife for our dental insurance and would like to find a pediatric dentist in Berkeley, Albany, El Cerrito, or Kensington who is in network.

I did some research and came up with the following names. Do any of you have any feedback on any of them? We want someone who is proactive and recognize issues. But we don't want to take him somewhere where he'll be overly babied because we don't him to get the impression that he should be afraid of or dread going to the dentist. The names that I've found are:

Dr. Nancy Ekram Elias and Dr. Roxanne Gould in Berkeley

Dr. Patrick Ting and Dr. Vivienne Valdez, Pediatric Oral Wellness, Albany

Any feedback that you have would be appreciated. REcommendations to any good pediatric dentists in the area that take MetLife would also be appreciated.

Thanks
