I haven't actually done the program itself but i've read her book and spoken with her through an online seminar she teaches for practicioners- it seems like an excellent, well thought-out program! I think it costs significantly more than the other ones included in the books (like Howard Schubiners or David Schecters) so i'd probably be more inclined to do the low cost ones first and see how that goes. The ideas are all similar but phrased differently in each program and with slightly different exercises.
