Billy Kissa

Belgium / Greece

Billy Kissa is an actress , improviser, coach and director from Greece won over by Improv Theatre, based in Brussels, Belgium. At a very early age she realised two things about herself. She wants to have a lot of pets and the only job that can make her happy is acting. She can proudly say that she managed to do both! Her main interest and passion is creating intense complicated characters and telling stories. And cats. And dogs. And donkeys. And capybaras. Let’s say, if there’s an animal around, there’s a big chance Billy is somewhere close. She is proud to call herself a cat whisperer, so if you want to talk to her, there is no better choice for a conversation starter than asking for advice for a cat related issue!
