Welcome !

TISS has a long-standing valued tradition of excellence in arts, mathematics, science, technology, athletics and community involvement. Staff, students and parents work collaboratively to encourage students to perform to their fullest potential.

It is my honour to serve Thousand Islands Secondary and Intermediate school as principal this year. TISS is a very special school that serves all students’ academic pathways - school to work- school to university- school to apprenticeship- school to college. TISS is very well known for excellence in athletics as well as academics.
