    I find him to be pleasant and professional. He knows what is going on with me and is able to discuss whether I need any addtional vaccinations or tests. He pays attention to me when I am with him.

    He's great and is amazing at making diagnoses and prescribing the correct medication based on my circumstances and needs. My only suggestion is that he doesn't spend enough time with the patients. In the 4 times I've gone to him, I think I've spent a cumulative of 7 mins total chatting with him about my symptoms. I don't know if that's a good thing or not. But, just saying it's a very short amount of time, just in general.
