Grace International School (GIS) Chiang Mai

Grace International School (GIS) opened in Chiang Mai in 1999 with 176 students, founded by Gene and Sherrie Foltz. It was set up mainly for the children of Christian workers serving in Thailand and the region, and today has more than 500 students from families linked to over 85 organisations working in more than 40 countries. Since the 2019/20 school year it has been on a purpose-built 37-acre campus in Hang Dong, south of the city.
