Captain Lukas Grippa and Co-Captain Alexander Smith lead the Improv meetings on Wednesdays after school (which are, by the way, now being moved to every Tuesdays and Thursdays after school), and are supervised by World Literature, Drama, and Stagecraft teacher Paul Vega.

Improv, in Lukas' words, "essentially, is creating a scene off the top of your head." The people who go on stage do not use scripts. All they have is an idea of what they want to do on stage, and they go with it.
