D.P.
If you are talking about the place on Burnhaven Drive (I think you are), I take my 5-year-old there. She sees Deanna Alevizos and really likes her. The rooms are all decorated in different kids' themes, and they are really good with kids there. Not to mention the fact that they get to pick a 'prize' each time when they leave - what kid wouldn't love that? :)
I will say that I thought the dental hygenist wasn't as patient as she could have been with my daughter. To be fair,though, if I had to deal with kids freaking out all day long, I probably wouldn't have much patience either.
All in all, I think it's a great place to take your kids. I would definately recommend it.
