William Moy is a grandmaster of Ving Tsun (Wing Chun) Kung Fu. He is a 10th Generation disciple of Ng Mui - the creator of the Ving Tsun Kung Fu system ^[1] - and the son of Grandmaster Moy Yat, who studied under Grandmaster Ip Man. ^[2]

Though Grandmaster Moy teaches traditional Ving Tsun principles - including centerline theory, facing, body leverage, and hand unity - he believes it is the Sifu’s role to ”give the students the foundation, and allow them to explore their own style” ^[3]. Ultimately, he considers “a brilliant teacher [as] one that inspires you to reach higher goals.” ^[4]

He emphasizes attention to detail, in body mechanics and hand position, as well as in artistry. Thus, the documentary series “American Kung Fu” contended that “his mastery is not only noticeable in his physical Kung Fu, but also in the way he lives his life.” ^[5]

In addition to teaching his own students, Grandmaster Moy participates in televised videos ^[6], recorded lectures ^[7], and demonstrations ^[8] to promote and advance the art of Ving Tsun. He was featured in video lessons created by Grandmaster Moy Yat ^[9]; served as one of the models demonstrating the long pole form and applications for the instructional text “Luk Dim Poon Kwan ^[10]"; and designed the cover for the book “Dummy: A Tool for Kung Fu”, which illustrates the 108 Muk Yan Jong techniques ^[11]”.

Grandmaster Moy is a Level 8 Grand Master Certified Instructor and leader of the International Moy Yat Ving Tsun Federation ^[12]. His school, located in New York City, is the headquarters for Moy Yat Ving Tsun Kung Fu schools, which include locations across the United States, as well as internationally, in Brazil, Canada, and Mexico ^[13]. He is the Global Director of the Moy Yat Institute network, based in Sao Paulo ^[14].

Grandmaster Moy moved with his family from Hong Kong to Brooklyn, New York in 1973. He attended the Pratt Institute. He resides with his family in Long Island, New York.
