The Brothers of St. Gabriel came to Chiang Mai and established Montfort Primary School in 1932 along Charoen Prathet Road on a 5-acre (20,000 m2) plot of land provided by Bishop Peross from Luang Anusarn Suntorn who gave his financial support at no interest.

The land was located along the Ping River, approximately 200 meters from the Sacred Heart Church.

The school has two teaching syllabuses: normal and English.
