The Big Ideas Forum is a regular community event held at Glen Street Theatre, engaging our local community in the robust exchange of ideas.

The Forum is an opportunity to engage with people you might not otherwise meet, hear opinions you might not otherwise hear, and come away from the experience an active participant in democracy, rather than a passive observer.
