“This was my first visit. He had ...”

This was my first visit. He had completely reviewed my history. I had been to WPH ED/inpatient a lot. He was easy to understand and wanted to make sure I understood my condition.Very friendly and positive. Was able to understand my concern and responded in detail. There was only one thing that was not in the file, so I brought it with me.
