The latest school updates
A group of High School students conducted sustainable tourism research in Thailand.
Sophia Migdalski (Class of 2025): " When you're having fun and being genuine on stage, whether you're singing or engaging in any other activity, the audience will naturally have a good time watching you."
Natsuki Uchino (Class of 2024) "Within sports, mental strength—not only physical—is always something you need to work on. There will always be ups and downs in your performances, and it is important to know that it is normal"
Congratulations to all of the students who performed and worked backstage on this fun and festive musical!
Kokomi Sakurai (Class of 2029) "One of the most challenging things I must overcome is showing up, even though I know each practice will be uncomfortable and hard."
