    Well, was introductory visit. He is very calm, was on time. I didn’t have to wait for him to show up. He took time to listen to me and gave me the opportunity bring up any issues I could remember. He answered my questions. Glad I changed doctors. He was very kind. I didn’t feel rushed.

    He recommended more exercise! I always expect doctors to push medications but instead he suggested working my body harder. And he was right. I’m more inclined to take his advice because of this.
