Welcome to the International Program at Sunflower Trilingual School.

My name is Simon Gauci, and I am the Headmaster of the International Program (IP) at Sunflower Trilingual School (STS). Originally from Ontario, Canada, I bring over 25 years of experience in international education across six countries, and I’ve been proud to call Thailand home since 2018.

We are excited to offer the International Program for Grades 7–12, which will be rolled out over three years. This program offers students a globally minded education rooted in international standards and supported by global partnerships. The International Program emphasizes academic excellence, global citizenship, and critical thinking through inquiry-based learning approaches such as STEAM, project-based learning (PBL), and thematic instruction.

Our school is proud of its 20-year legacy of nurturing well-rounded, multilingual learners. STS recently celebrated two major milestones: our 20th anniversary and receiving the Royal Award for Secondary Schools for the third time in a decade.
With Thai, English, and Chinese integrated into daily life and learning, students become fluent, confident communicators. Our goal is to help each learner explore their passions, understand themselves, and visualize a successful path forward—both academically and professionally. This integrated international curriculum prepares students to have a clear understanding of their interests and be able to visualize the career path they want to take.

Welcome to a vibrant, forward-thinking learning community. We’re thrilled to have you on this journey. I encourage you to review our website and then contact us if you have any questions about our unique programs.
