They've never used foul language, which has bothered me at some of the other places I've been too. They always make an extra effort to be polite and courteous. Their primary concern is my safety and comfort, and they always take the time to address every concern of mine immediately. Not only do my appointments never get canceled last minute, they take time out of their day to send me a reminder so I don't forget. They are extremely reliable. It was nice of them to offer some sample toothbrushes and toothpaste for me to take home. I was able to figure out which toothpaste I liked without having to buy anything. I like to keep records of everything I spend, so I was planning on asking them for an invoice for my procedure, but they gave me one before I even had to ask. I was impressed with their professionalism.
