International Symphony Orchestra of Sarnia and Port Huron

About

The ISO is Ontario & Michigan’s combined Symphony Orchestra. The ISO was established in 1957 through the merger of two local music groups: the Little Orchestra Society of Sarnia and the Port Huron String Ensemble. We are a nonprofit organization comprising over 100 musicians from both sides of the U.S.-Canada border. The ISO brings full concert seasons and educational programs to the bridged communities, creating a unique cross-border cultural connection.
