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.

Dr. Lazarev is an excellent and personable physician. He always ensure that I'm receiving the best care, asked me questions, help me to know and understand next steps (e.g., scheduling tests/procedures). But, for me, the most Important thing is that he shows genuine concern for my health and well-being; and he always greets me with a smile!

The appointment I originally made was far beyond when I wanted to be seen so I went on a waitlist and got in to see the Dr much sooner than my original appointment which made me very happy.
