I am not a certified Qigong massager (but I would wish so
), but I took the Qigong Massage Seminar with Master Yang last summer in Boston. It was really good and worth it. Unfortunately, it might take a few years before he gives the same seminar again. (Although he might give it before at special events like Taste of China…) Master Yang also gives a special Tui Na massage seminar, but I don't know the schedule.
But to take this Qigong massage seminar, you must first attend the (Basic) Qigong seminar (which is great by the way
). He gives this seminar every year.
Also, Master Yang wrote a book on massage and I think it is a really good base. It is comprehensible and you can practice a lot before going to the seminar.
Hope this answer some of your questions!
