In 1888 Daniel McGilvary, an American missionary of Scottish origin and founder of the Laos Mission, established a church house and a school in Chiang Saen District, Chiang Rai Province, which he named "Boys School".

After less than twenty years this school was moved to Chiang Rai city, to its present location near the Overbrook Hospital.

The compound includes an office building, a swimming pool, playgrounds, two dining halls and a cafeteria.

The school has a library and a stationery store, as well as two health care facilities, one in the northern wing and the other in the southern.
