Priam has practiced diabolo for 23 years, and has been a professional juggler since 2004. Practicing alone at the beginning, he created dozens of new tricks with 1 and 2 diabolos. He was one of the first diabolists to put diabolo videos online in 2002.
Since 2000, Priam has taught diabolo workshops and masterclasses all over Europe in French and English, mainly in juggling conventions and circus schools.
He created the Art Of Diabolo Society, which aims to develop the art of diabolo in all aspects. In 2003, Priam invited the best French diabolists to create The Mad French Posse and to create the Diabology DVD, knows as the Diabolo Bible nowadays. With JiBe, they introduced the siteswaps theory for 2, 3 and 4 diabolos.
