I've been with Kent for quite a long time now. He has a great location in the Pike Place market near my work.
I've never really had any complaints about Kent; he gets the job done and responds to things that I request. He has a good attention to detail, and points out the smallest of potential trouble areas so that I can focus on them more. His staff are all nice and laid back, and do their jobs well too.
I have not had any cosmetic surgery done with Kent, primarily just cavity visits and cleanings.
