In my experience I found her not to have the level of knowledge and expertise expected. Suspect either poor listening or poor comprehension skills as she researches and answers questions not asked, while failing to respond to those actually asked then charges both meeting time and research time.
Initially found her to be basically competent in elementary tax matters (ie turbo tax or other software might do just as well) but would suggest seeking expertise elsewhere if your situation has any degree of complexity or variance to vanilla 1040.
