Dr. Tada and her staff are extremely professional, helpful and personable. The work they do is excellent and all my family and many of our friends go to her.
I'm not sure how her costs relate to other dentists, but I know that I wouldn't pick a dentist because they were cheap.
The office atmosphere is pleasant, adequately equipped and comfortable, but not "spa-like" (I wouldn't want to pay extra for that, anyway).
But you can't beat their view of San Diego Mission Bay and you couldn't ask for a nicer group of people.
