Is there anyone that is familiar with the American Jiann Shyong Kung Fu Center and their instructors?

The following is a link to the school’s web page.

They have offered classes in many different styles of Northern Praying Mantis Kung Fu over the years.

Some of the styles they offered instruction in were Seven Star, Tai Chi, Tai Chi Plum Flower, Plum Flower, and Se-Ru Bun-Da.

I would appreciate any feedback.
