Your Impact Matters

ISO Membership Program

The International Symphony Orchestra’s 65 seasons would not have been possible without the incredible generosity of our volunteers, associations, musicians, singers, members, and so many others. Your time, talent, and dedication have shaped our legacy and our future.

As we reimagine how we bring music, culture, and education to our bridged communities, we remain especially grateful. We were among the last orchestras on the continent to resume full concert operations—and your continued support means more than ever.

To our extraordinary communities, sponsors, and local businesses on both sides of the border:
Thank you for supporting your symphony.
