Welcome to

Sunflower Trilingual School

Sunflower Trilingual School (STS) is a private English Program institution based in Samut Sakorn, Thailand that offers education in three languages (Thai, English, and Chinese) from grades one to twelve. Our goal is to foster a learning environment where the student will not only be good citizens who contribute to the peacefulness and prosperity of the society, but they will also be successful and happy leaders in an all professional in the future. 

Every child is unique. By giving them the chance to learn, experience new activities, and express themselves freely, we stimulate their individual learning ability in order to bring out the best in them. We aim to create a solid foundation for independent learning which will stay with them throughout their entire lives. 

The Sunflower Group consists of Sunflower Kindergarten School and Sunflower Trilingual School. We choose the sunflower as our symbol because, under any circumstances, sunflowers always find their way to turn towards the sun. We hope that children under our care and guidance will emulate sunflowers, and always follow the right path. We hope they will learn and seek out knowledge eagerly, and independently, to ensure bright futures for each and every student of The Sunflower Group.

It is, therefore, our responsibility to initiate, encourage, and challenge their independent learning ability. We will help them to learn and grow into being their best along the way - no matter when or where they are.
