I wish this survey request came sooner, as I've forgotten the specifics of my appointment. Alyssa is very nice and highly intelligent, a rare combination these days. She does instill a sense of confidence because of her apparent knowledge of her field. She does seem to be quite a bit hurried, and tries to give enough time to address her patient's issues. I find I've recalled issues I've wanted to address just after she's left the room. This is the only reason I gave her a 4-star vs 5-star rating.
