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. When comparing them to others I have visited for the same condition, they are among the best I have seen. I love that they are always more than happy to answer my questions, and actually welcome questions. I've felt awkward at some other places I've visited when I've tried to ask a lot of questions, but not here.
