Yeah, my best dentist experiences have all been with a practice where it's just the owner (or a family operation). Practices where it's a bunch of dentists in some corporate thing never have been as good.
I will say that I did have a bad experience with one where the support staff was all family of the owner, because the receptionist mom was a miserable person and the hygenist wife was rough with the cleanings.
The one I'm at now is great, it's a solo female dentist and all of the support staff are relatively young women, they don't advertise as being specifically all women, I think it's just how it works out since most hygienists are women traditionally. But the younger hygienists definitely have a softer touch doing the cleanings and are better at giving information and tips while doing so. Has made me realize the hygienist at my old office was just unnecessarily rough and terse for no reason during cleanings.
