Let's Start



Dr. Thomas Hamilton



Dr. Thomas Hamilton has been working in international education for over two decades, in countries like America and Korea, but most of his career has focused on education leadership in Thailand. Thomas has taught students from over 30 countries, from first grade to graduate education, as well as holding leadership positions in three different schools.

After finishing a bachelor’s degree in English Language Arts (Secondary Education Teacher Qualification Program), Thomas’ passion for literature led him to pursue master’s and doctoral degrees which focused on teaching reading and writing. In the classroom, Thomas’ lessons focused on literacy skills, specifically emerging literacy with younger learners, and academic/research writing with older students.

While working with Asian students, Thomas became concerned that the region’s prevailing pedagogical approaches were not sufficiently preparing students for the challenges of research writing required in graduate education. This led Thomas to pursue opportunities for education reform in Thailand. After focusing his career on education leadership, Thomas obtained postgraduate certificates in Education Leadership and in IB School Leadership.

At Raffles American School, Thomas has worked with the school’s Executive Board of Directors to establish an opportunity for students in the region to become creative, autonomous learners that are truly excited about the learning process.

Preschool & Elementary Principal

Ms. April Cruz


April has been teaching students from Kindergarten to Grade 8 for over a decade. April started teaching in America where she completed her California teaching license and Master’s in Education. Before joining RAS as the Elementary Principal, April helped design and led the IB PYP and WASC accreditations for another international school. April’s experience with the Elementary division of IB (PYP) has been a great asset to Raffles American School as we prepare our teachers and students for the IB program.
April believes in fostering each student to their fullest potential. School and the classroom should be a safe space for children to have enriching learning experiences and opportunities to learn about the world, the world around them, and most importantly, be ready for their college and careers in the future.

Middle & High School Principal

Mr Kyle Young


  • M.Ed International Education Administration (USA)
  • B.Ed Junior & Intermediate (Canada)
  • HBA English (Canada)
  • B.Sc Natural Sciences (Canada)

15 years in education, 9 years in Senior Leadership

Personal Statement: 

Kyle’s greatest passion as an educational leader is in watching happy students and teachers collaborate and grow in meaningful ways. At RAS that means leading innovative change year round that benefits our whole community and results in ever-increasing academic excellence. Above all else, he values relationships with teachers, students, and parents, and finds leading a school community one the most rewarding experiences of his life. Over the past decade, he has experienced and contributed to educational improvement in a variety of ways in Canada, the UK, the US, and Thailand. His experiences as a Classroom Teacher (G3-10), Discipline & Department Head, Accreditation Coordinator, Divisional Principal, and Head of School/Principal have lead to his belief in constant growth and progress, and that all students and teachers are capable of both.

Kyle’s primary goal at RAS is to lead lasting school improvement, and to develop a culture where the status quo is feeling good about the changes that take place because they ultimately propel our students and staff to overall excellence. Teachers remain indisputably the greatest resource in any school, so treating them well, building up their skills and confidence, and valuing their contributions and endless effort, are the greatest ways to ensure our children get the exceptional international educational experience they deserve. At the end of the day, success is marked by the number of students and teachers who not only learn and grow, but also think of RAS as a family.

Alex believes in the importance of building skills in the classroom that will help students in whatever path they choose to take after high school.
