KEN
Kenny Finister
Adult Muay Thai Instructor
My name is Kenny Finister, and I have 24 years of experience in Muay Thai, including over 50 fights, training high-level fighters, and promoting events. I've worked with both amateur and professional boxers and have played a role in the growth of the sport.
Outside of martial arts, I'm a proud father, supportive brother, and enthusiastic mentor. I believe in the balance that the martial arts lifestyle brings. I also love cooking, exploring dishes from different cultures, and have a passion for music, having performed in genres like Roots Reggae, Jazz, Blues, and Samba Reggae. One of my lesser-known interests is reading about law. My goal is to inspire others to reach their full potential and thrive.
