Sifu Steve Cottrell

"Sifu Steve Cottrell began studying Kung-Fu in 1966. He has trained in several styles of Chuantong (traditional) Gongfu but reserves teaching to three fighting arts: Wing Chun Kuen (Everlasting Spring Boxing) in the Yip Man tradition, Bei Tanglang (Northern Mantis Boxing) in the Wong Hon Fun tradition and Taiji Quan in the Yang Banhou tradition."

Weirdest thing ever. I met this guy at a Wing Chun competition in Ohio or Maryland years back. I had no idea he did Seven Star. He's a pretty good Wing Chun guy and has made some videos for WC. I wonder if he has Seven Star videos as well...?

Here is a video of various Mantis masters. Steve is the second guy.
