      I like Dr Lazarev and I think he really knows GI, but he doesn't make eye contact during visits and although he is listening to everything I say, he is typing the whole time. It'd be great if it was more of a conversation.

      The appointment I originally made was far beyond when I wanted to be seen so I went on a waitlist and got in to see the Dr much sooner than my original appointment which made me very happy.
