They've never been late to any of my appointments. I've even showed up early sometimes and they've always been ready and prepared. When comparing them to others I have visited for the same condition, they are among the best I have seen. 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're always able to answer simple questions over the phone. They only make me schedule appointments if necessary. I am always so impressed with how quickly my calls are answered here. I am never put on hold for a long time and love knowing that if I have a quick question I won't have to wait a half hour through terrible music to get it answered.
