It was nice to see them treat their staff with so much respect. It was obvious that they had a good relationship with all of their staff members. I loved how gentle and careful they were while they were flossing my teeth. My gums didn't bleed at all. I was glad that they were located in a safe neighborhood. I've been to some other places where I was scared to get out of my car but not here. I don't think they have any qualifications! There definitely wasn't anything displayed.
