Established in 1968, Our Lady of the Snows High School has completed over 55 years of service in the valley. The school was founded under the patronage of Bp. Alfred, Fr. Emmanuel, and Br. Thomas, and was initially named 'The Bishop Alfred Grammar School'.

As student strength grew, the administration shifted the school to a larger premise in Dhalpur, where it continues to operate today. OLS was a pioneer in bringing the CISCE board to Kullu, supported by a team of dedicated staff and teachers from the Shimla and Chandigarh Diocese.
