回複：請問哪一家牙醫診所在Chino Hills 比較好

I would recommend to check with your friends, neighbours, colleagues, etc. How do they like or dislike some offices? All practicing dentists have pretty much the same knowledge yet very different personalities, and that may be the most important factors in choosing your own. If you don't have those resources, then you surely can follow BZ's advise.

Good luck.
