My visit was the first time I had seen Kayla Day, APRN. She was quite thorough. She had actually reviewed my history, unlike other providers that want you to supply your history even if it is in Epic. She listened to my questions and addressed my them. I didn't feel rushed and she appeared to genuinely listen and care.
