Who runs SPARK ?

The SPARK team is made of two improv nerds, passionate about the art and craft of improvised comedy.


Salomé Attias is a French-sounding, English-speaking urbanist, creative consultant, theatre maker, improviser, trainer, and many other fancy terms her parents don’t really understand.  She regularly teaches and performs in Paris, Amsterdam, and Rotterdam. She’s currently active in the all-female improv team That Time of The Month and performed with musical improv group Unmuted, Boom Chicago’s house team Hocus Jokus and (too) many others improv mischiefs. 

Salomé is also in charge of corporate workshops. Want to book one for your team?

Harry Sidiropoulos is an engineer by trade and by way of life. In a young age he liked making stuff involving batteries, motors, Lego, play-doh, spaghetti, usually ending in loud bangs or blown fuses. That passion for “making” never stopped! In 2015 he started Improv and realized two things: i. It’s much better to create with other people and ii. in Improv there are significantly lower chances of electrocution. Since then he’s been on stage improvising more times than he has blown fuses (countless times) all around Greece, Rotterdam, Hague and Amsterdam! Currently he is nerding out in improv workshops and co-running SPARK with Salomé Attias.
