They would never suggest that I buy something that wasn't necessary, and never pressured me. They were always very considerate and professional. I've been to one or two places that had a really bad smell. I was worried I would encounter it here too but I didn't notice anything. I was worried that they were going to wear an obnoxious cologne, because I've dealt with that at other places, but they didn't even wear cologne. It was fantastic to be able to breathe freely the entire time. They made the extra effort to make sure every question and concern I had was addressed. They have a very good professional reputation. I know that I'm under the care of an expert.
