6 International improvisers from all over the world

Billy Kissa
Belgium / Greece
Billy Kissa is a Greek actress living in Brussels, specializing in Improvised Theater. After graduating from the “Theater of Arts, Karolos Koun”, in Athens, Greece she started working as an actress in scripted theater, teaching and performing improv all over the world. She studied Meisner technique with certified teachers and taught improv and acting to adults and teens. Billy is part of the European Network for improvisers “The SIN”, one half of the duo show ECHO with Raschid Daniel Sigdi and director of the All Female Cast Show “Huntress and Healer” and the unscripted play “The Dark Age of Love”.
Challenging herself is one of her strongest qualities, with the last challenge being her very recent dive into the terrifying world of stand up comedy.
Gael Doorneweerd Perry
Netherlands / France
Gael has practiced improv for more than 15 years in Strasbourg and then Amsterdam. He is the co-founder of Flock Theatre, Anananas & Pampamplemousse (formerly La Carpe Haute), as well as the SIN, an international network of improvisers in Europe, and Safe Play, an community working towards a safer improv field. He just handed the artistic direction of IMPRO Amsterdam over, he is the co-Artistic Director of Improfestival Karlsruhe, and Artistic Director of the Flock Festival in Amsterdam. In short: he creates a bunch of stuff!
He loves to teach abroad and to create new shows to explore and share his passion, including with his partner on and off-stage, Laura Doorneweerd-Perry. After touring the world with their show Object of Affection, he settled in Amsterdam and they created Flock Theatre together: a school and a professional company, to produce unscripted theatre and invite other artists to collaborate.
Some of his latest international collaborations involve Diego Ingold, Inbal Lori and Katy Schutte, with whom he’s created new and very different duo shows.
While traveling, Gael found a thousand ways to improvise. These result in his unique style: both physical and noisy, kind and silly, full of emotions and slightly crazy.
