Hi, this is about John Fogalas. I wanted to impress that I was very surprised that the time went by so quickly. We had a lot of complicated issues, seven different buckets of symptoms that we asked John to help my wife and I sort out. And he was able to do that. And he took the extra time. It was over an hour for him to be able to do what he did and explain and answer all of our questions. So I really value that. And I didn't feel rushed. And the second thing is that he knows me.

Normally my doctor is excellent, but on this occasion I was disappointed. I could hear through the wall (without making out any of the words) that the previous patient kept the doctor talking a very long time. Consequently, he arrived a half hour late for my appointment and seemed stressed and worn out. Moreover, he was in a rush to catch up in his schedule and did not give my case as much attention as he normally would have. For example, the nurse had talked to me about getting a flu vaccine while I was there, but that was forgotten. Also, I had two medical questions but only the primary question was answered before I was ushered out. Avoiding the stress of the previous appointment with a difficult patient carry into the appointment with the next patient is an area for potential improvement.

This is not specifically about Dr. Tsongalis, but I find the apparent lack of communication between providers a little off-putting.
