The Big Ideas Forum is a quarterly event at Glen Street Theatre that engages the local community in the robust exchange of ideas.

The Big Ideas 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.

What's your Big Idea?

Big Ideas is your forum, not ours. So if you have any idea for what you want the next Big Ideas forum to look like, we'd love to hear from you! Contact our Community Development team via
