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 found Kung Fu and Tai Chi to be both exciting and extremely challenging. The concepts, applications, and even teaching styles were quite different from what he had experienced with the militaristic arts of Karate and Tae Kwon Do. Eventually, after many years of growth, he received his black sash in Huaquan Kung Fu in 2013. He met Master Andrew Bloch at Warrior’s Way in August 2015. He re-opened Warrior’s Way as Metrowest Kung Fu in January 2016 under the guidance of Sifu Gary, with support from Master Bloch and the other instructors from Warrior’s Way.

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. In addition to enriching his students and his community through the virtues that martial arts training provides, Sihing aspires to increase the awareness and appreciation of Kung Fu as a fighting art within the greater martial arts community.

In his free time, Sihing enjoys doing anything outdoors (especially snowboarding and surfing,) photography, reading, and videogames.

Katina Fontes

Katina has been a yoga practioner for 12 years and an instructor since 2010. Her yoga classes incorporate elements of several styles of yoga, and focus on healing injuries, improving health, and calming the mind.


Master Andrew Bloch

Master Bloch has been training in Tae Kwon Do and other arts since he was a teenager. Having played many sports and done many activities, Tae Kwon Do kept his interest as nothing else had. Master Bloch began as an assistant instructor as a green belt back in 1995 and has been teaching martial arts ever since. In college, he founded the University of Connecticut Tae Kwon Do Club, and later in life, founded Warrior’s Way, a martial arts and yoga studio in Maynard. Currently, he is teaching at the Longfellow Club in Wayland and at Metrowest Kung Fu in Maynard, as well as offering seminars to many other schools. He recently achieved his 5th dan black belt.

Master Bloch’s Tae Kwon Do is more art than sport. While he competed in numerous high-level tournaments, his personal philosophy on the martial arts leans towards the traditional rather than the modern. A student’s technique is developed for its traditional use; defending oneself from harm. Master Bloch also has a background in several other martial arts, so it is not uncommon for useful techniques or philosophies from other arts and other teachers to find their way into his classes. Perhaps the most significant aspect of Master Bloch as a teacher is the sincere belief that everyone can benefit from martial arts, and the only person any student should be competing with is him or herself.

Michelle Masella

Michelle has been practicing yoga for over twelve years. Always interested in fitness and holistic health, she immediately fell in love with how a consistent practice made her body and mind feel. What started as a mostly physical practice, morphed into a tool for navigating through life’s challenges. As a busy mom and special education teacher, she loves the notion of using yoga principles off the mat. She has a desire to share the balancing effects of yoga with others. Michelle completed her 200-hour certification with Cindy Boulter at Revolution Community Yoga in Acton. Additionally, she holds a Master’s Degree in Education and feels her experience in the classroom aids in her understanding different perspectives and how each class can be a unique experience for the participant.
