I had a lot of anxiety coming in, after having health issue lately. He put me at ease right away, making jokes. He was so informative and took plenty of time to make sure that I understood everything he was telling me and let me ask questions. He's great!
The office was very clean. The doctor was extremely friendly and answered all of my questions.
