She was concerned that the culture was changing and their native language was disappearing. She first began to teach the Slimmmon language by opening an alternate school on the reserve. Later the Sliammon language classes where moved to the old Brooks Junior High School. In September 1991, she approached the school district and started working with students at James Thomson School. She ran the language program there for 8 years. Marion Harry has replaced Sue as the Sliammon language instructor while Sue continues to work on the Sliammon reserve with the kindergarten students.
