Kostas Dervenis was born in the United States in 1959. After receiving degrees in Chemical and Materials Engineering, Kostas pursued a career in the defense industry. In 1990 he was the Engineering Manager for the Greek F-16 program, and in 1992 decided to settle in Greece. He was worked in the academic, telecommunications and software sectors since that time.
Kostas joined the Martial Arts world at the age of ten, beginning with judo and boxing. Throughout his life, he has trained in karate, judo, jujutsu, ninpo taijutsu, kung fu, and tai chi chuan. Having surrendered all other ranks in the oriental arts, Kostas retains a 5th Dan in Jujutsu/Jojutsu under Professor Andrew Yiannakis of New Mexico.
In 1984, while studying materials engineering in Atlanta GA, Kostas became a student of the well-known weapons-master and Western-style fencing researcher Hank Reinhardt, driving an early and fundamental interest in the Historical European Martial Arts. His work was referenced by Bettany Hughes in her book, "Helen of Troy," and he was cited as an expert on Bronze Age combat in the accompanying Channel 4 documentary. Kostas’ book "The Martial Arts of Ancient Greece" has been included as a reference for the degree program at the US Army War College.
