The Pammachon Cultural Union (Πολιτιστική Ένωση Παμμάχου) is a non-profit organization legally recognized by the Hellenic Ministry of Culture, following a court order in March 2007, to promote Pammachon worldwide, after almost vanishing in this generation.

That court order in the country of Greece recognizes the following statement:

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.

Kostas’ study of the evolutionary factors of hand-to-hand combat has been lauded by military and academic authorities alike. Several commendations for his work are listed below.
