|Home >> Our History

Trinity International School (TRIS) was founded in 2003 in the Sukhumvit area of Bangkok, Thailand. TRIS was created with the belief that all families in the area, whether expatriate or Thai, deserve an opportunity for a quality International School education at an affordable price. TRIS is centered on Seventh-day Adventist (Adventist) values and tenets of education, and we follow an American System as represented by the State of California Department of Education and Common Core standards..
