Sergei is a professional fighter and trainer from Ukraine with over 24 years of experience in combat sports. His journey began in 2002 at the age of 14 with Muay Thai — a discipline that remains the foundation of his style and philosophy to this day.
His impressive amateur career includes over 200 fights on both national and international levels. Sergei became multiple-time World Champion in Thailand and won the Ukrainian National Championship seven times.

For his outstanding achievements, he was awarded the title “Master of Sports of International Class.”
Today, Sergei continues to live and breathe the sport, training with the same discipline and passion that defined the beginning of his career. In addition to Muay Thai, he teaches kickboxing and classical boxing at a professional level. He also integrates functional training methods and CrossFit into his coaching approach to develop strength, endurance, and elite-level athleticism.

Captivated by the world of martial arts from a very young age, Nathan Melliger took his first steps in Taekwondo before unleashing his fighting passion in kickboxing. He later perfected his striking in Muay Thai, becoming the embodiment of concentrated power and tactical finesse.
Driven from childhood by discipline, passion, and an insatiable desire for self-improvement, Nathan Melliger transformed the initial spark of his youthful fascination into an impressive martial arts career. Where others saw chaos, he forged strategy and focus, shaping his mindset into an unshakable force. His expertise emerged from countless hours of hard work and fights — from precise strikes in kickboxing to explosive combinations in Muay Thai. His recent pursuit of Brazilian Jiu-Jitsu completes his style, making him a versatile all-rounder.
In the last two years he has expanded his repertoire to include Brazilian Jiu-Jitsu and now proudly holds a purple belt — a testament to his ongoing development.
Disciplines: Muay Thai, Kickboxing, Taekwondo, Brazilian Jiu-Jitsu.
