They're always able to answer simple questions over the phone. They only make me schedule appointments if necessary. When comparing them to others I have visited for the same condition, they are among the best I have seen. They do such a great job of never overbooking appointments, even though they are extremely popular. I know for a fact that they have lots of business, but I've never had to wait a long time in a crowded waiting room like other places I've been too.
