Sun-style Bagua instructors?

[codaeus]

Has Sifu Wing Lam produced any qualified instructors of [u]Sun-style Bagua[u] that are teaching actual class anywhere within California? Tim Cartmell seems to be the only one I can track down, but he only teaches Sun Bagua by private instruction. I'm after an regular class (no private instruction, workshops, seminars, etc.). I live in Bay Area, but quite willing to move anywhere within the state. Again, I'm only after Sun-style Pa-kua Chang class! Thanks.
