I've only been in once, but the exam she performed was far better than any dental exam that I had had in the past 5 years. She's thorough, intelligent, attentive to detail and generally inspires confidence. I am looking forward to my next visits (as odd as no doubt that sounds given that this is dentistry we're talking about!).
One thing I should mention: her facilities get 5 stars even though she does not have 'spittoons' and uses an air-vacuum instead. This is more hygienic for the patient in the long run and so I prefer it. If you absolutely must spit then consider her facilities to be 4-star.
