See What Parents Have to Say About Our Campus
“I really like the teachers here, they are always smiling and are really kind, and it's great to see that they hold a lot of our family’s values. My kids also seem to really enjoy their teacher’s mentorship style. My children have started the PYP curriculum and are learning lots of things that I wish I had learned as a kid. My child loves the gardening classes, the school pet and anything to do with nature. We love to see that the education is very tangible and hands-on.”
Jeremy Carlson
Parent of Students in Early Childhood and Primary School“OWIS’s legacy and big brand presence were a focal point for us. Our son has really enjoyed the strong exposure to science, and today, I saw his presentation on economics. He knows so much more about economics than even I do, and he is just 10 years old!“
Rahul Kaushik
Parent of Students in Early Childhood and Primary School“Each day we have been greeted by teachers with warm smiles and genuine kindness - this left a deep impression on us. What touched us even more is how many teachers already remembered my son Eric & Ethan's names. Their homeroom teacher, Ms Mariko & Ms Michelle, have offered consistent encouragement and recognition, which has deeply reassured both our children and us as parents. We truly believe they will continue to thrive with this kind of support”
Arrow Xia
Parent of Students in Early Childhood and Primary School“You guys ROCK! Thank you so much for supporting Food Bank Kansai and spreading the word.”
