The school is fine . It teaches William Cheung's version of wing chun. Don't buy into the propaganda and just take the good stuff keeping in mind there is some bad as well like anything else. Phil Redman ,one of the teachers, is a good guy and has over 30 years in wing chun. I don't know Keith Mazza. TWC is nothing more than wing chun based on the weapon techniques of regular Yip Man wing chun. This is a simplification but covers the basics.
