About Our Instructors


Sihing Eliot Prisby

Sihing Eliot is the owner and head instructor of Metrowest Kung Fu. He has been practicing martial arts since 1993, when his parents enrolled him in karate lessons when he was bullied as a child. Sihing fell in love with the martial arts, and studied several different styles for many years, eventually receiving black belts in Karate and Tae Kwon Do. While attending Fitchburg State College, he founded the Fitchburg State College Martial Arts Club, which is still active today. In 2009, he began learning Kung Fu and Tai Chi from Sifu Gary LaChapelle. He received his black sash in Huaquan Kung Fu in 2013. He opened Metrowest Kung Fu in January 2016.

Sihing is a strong believer in traditional martial arts, and teaches Kung Fu and Tai Chi as he learned the arts from his own instructors. He believes that to practice Kung Fu is to temper the spirit by strengthening the body, and that anyone can do it if they are willing to learn. Sihing aspires to enrich his students and his community through the virtues that the traditional Chinese martial arts training provides.

Sihing enjoys the outdoors, snowboarding, surfing, photography, and reading. He lives in Maynard with his wife and daughter.

Sihing Eliot teaches all Kung Fu and Tai Chi classes.
