History of STS
Strathcona-Tweedsmuir School officially opened on a beautiful country campus in Okotoks, Alberta in September 1971. An amalgamation of Strathcona School for Boys and Tweedsmuir: An Academic School for Girls, the new school came about as a result of the generosity of W.H. Atkinson and the Cross Family.
Today, STS is a co-educational independent school community for Kindergarten - Grade 12 that develops well-balanced students for a life of purpose by inspiring excellence in scholarship, leadership, and character. STS' tradition in educational excellence spans more than 100 years through each of our founding schools: St. Hilda's School for Girls, Strathcona School for Boys, and Tweedsmuir: An Academic School for Girls and can be best summed up by the School's motto: Nil Nisi Optimum - nothing but your best.
