While we would love to be able to host every event that comes across our desks, we have limited staff dedicated to our events programming. Additionally, our event space is just a fraction of the work we do here at The Alliance Center. As a result, we reserve the right to refuse any event due to capacity and time restraints. Thank you for your understanding!
