Hello, live in geneva for a long time.
actually there is not so much wing chun club in geneva.
Concerning blackfox (it's a club not a guy), i heard that they had difficult time, and i some of the instructors left and practice now by their own, but i'm not 100% sure about that. Anyway check out the website

Another wing chun instructor who is related somehow with blackfox has it's own "club", check out the website
http://www.swca.ch/nos_cours.htm.
I don't know personnaly these clubs/instructors and i don't know where did they learn wing chun and with whom, i just heard of them.
Another instructor is andreas rampf who practices Leung Ting lineage wing chun kung fu (
http://www.ewto.ch/schools/41).
I don't know him either but i heard he is a competent instructor. His school, being affiliated with the EWTO, follows a strict program of progression in wing chun.
That's about what i know for wing chun in geneva.
Concerning me, I do practise wing chun kung fu for about one year in Sion with Ludovic Delaloye. It is about 1h50 from geneva by train.

It really worth to go so far. He is a direct student of Ip Chun.
And i'm actually looking for people to practice with in Geneva, so let me know.
What about you ? What lineage of wing chun kung fu do you practice ?
