I thought the appointment went very well. When I saw the chart update in MyHealth, there were a couple of things in my chart that he never mentioned at all.

as I mentioned before, he was excellent. Thoughtful and knowledgeable. He listened and came up with a good plan to help me meet my goals including addressing my sleep apnea, getting old by medicare, working across two geographies, and a making it happen as soon as possible.
