I have gone to Dr. Grace for four cleanings now and think he is terrific! He has a great bedside manner, is engaging and efficient and, most importantly to me, explains the importance of taking care of one's teeth WITHOUT lecturing! I have already recommended him to three friends, all of whom have raved about him back to me, including one friend who moved across town and still comes over to my neck of the woods to see him.
Dr. Grace also does all the cleanings himself, he doesn't farm them out to hygienists, like a lot of other dentists, which I really appreciate.
The facilities aren't great - as someone else noted there isn't tons of privacy - but they are more than adequate and are way less important than finding a great dentist, you can trust.
About Hygienist: I don't know the hygienist's name, but it's always been the same woman and she is super nice and friendly, and really only does x-rays.
