Global Vale Tudo Combat Sports Academy is led by its exceptional Head Coach and owner, George Constantinou, whose passion for combat sports started at a young age.

At just nine years old, George began studying Muay Thai, following years of training and competing in Tae Kwon Do under the guidance of Master Suchart. In 1997, he took the initiative to establish the first Muay Thai club in Nicosia, housed within the No Pain, No Gain Gym.

Driven by a relentless pursuit of excellence, George traveled to Thailand in 2001, where he trained under the supervision of renowned Muay Thai trainers at the Official World Muay Thai Council Camp (WMC) in Ko Samui.

During his time there, he received invaluable guidance from esteemed figures such as Master Sok, Master Hanarong (an eight-time World Champion), and Stephan Fox, the Secretary of IFMA and Vice President of WMC. His dedication and hard work led him to compete in the World Muay Thai Championship (IFMA) in Kazakhstan, where he secured an impressive third-place finish with the guidance of Mark Hunt, the 2001 K-1 World Champion, in his corner.

George's expertise and contributions to the world of Muay Thai were recognized when he became the official representative of the United States Muay Thai Association for Europe in 2004. Subsequently, he earned his Muay Thai Senior Instructor certification from the esteemed Rangsit Muay Thai Institute in 2009, which holds approval from Thailand's Ministry of Education. His thirst for knowledge and growth led him to train and compete alongside the legendary Muay Thai fighter Sangtiennoi Sor.Rungroj.

In addition to his profound Muay Thai journey, George embarked on his Brazilian Jiu-Jitsu (BJJ) training in 1998 at the Norwich MMA Academy during his studies in informatics at the University of East Anglia.

Over the years, he continued his grappling training in Cyprus, learning from instructors such as Theo Rallis and training at prestigious academies like Renzo Gracie Academy Cyprus. His BJJ journey took him to the United Kingdom, where he trained under UFC veteran Danny Mitchell at Combat Base BJJ.

Upon returning to Cyprus, he further honed his skills under Nick Unander BJJ and, after Nick's relocation, resumed training with Renzo Gracie in 2017.

In 2023, he reached the pinnacle of his BJJ journey, being officially awarded the prestigious black belt by the International Professional Jiu-Jitsu Federation.
