Tyrone Angolia

We here at Benevolent Fist are absolutely dedicated to being better. We are mindful that martial arts are a meta map for the rest of our lives and the more we set/reach our martial goals the more we know we can set & reach all our life goals.

Sifu Tyrone Angolia began training in Praying Mantis Kung Fu in 1994 and was fortunate enough to train with his Sifu for the next ten years. In 2003 he became a successor of the Chen Zhen Yi lineage of 7 Star Praying Mantis Kung Fu. Following this achievement, Benevolent Fist was born and he began teaching at the Core Star Center. In 2007 Tyrone began training MMA and then started to compete the following year. Thoroughly enjoying competing in MMA matches naturally led him to training in Jiu Jitsu.

Having a passion for teaching martial arts, he became a BJJ instructor at Performance Martial Arts where he holds the rank of brown belt under Ben Baxter. Tyrone’s path to excellence is paved by helping his students increase their kinesthetic awareness, neuromuscular connection and overall muscular endurance through martial arts and conditioning.
