Jan Silberstorff is one of the few Westerners who deserves the title of Chen Taiji Master. He is from Germany and was Chen Xiaowang's first Western indoor disciple.
He is in Seattle this week at Kim Ivy's school. Here's a pdf schedule. You still have time to attend tomorrow if you're in the area.
Next week he'll do a workshop in San Diego at the Taoist Sanctuary.
I've heard that he is someone you want to experience if possible.
