5.0 Works Here
7/10/2025
I love working here. There is a stong sense of community and love. Our motto is One Team and I feel a strong sense of One Team while being on campus. This is my home, my life. I have never worked for such a loving work place ever in my professional career. I love being on campus with the students. It's a very uplifting loving environment.

My experience has been decent at 'Iolani, but parts of it definitely feels quite exclusive. When I first came here I was pushed with the idea of the "One Team" motto, but felt the opposite of that. Some teachers are terrible here but there are really great ones too. Sports are good and there's resources and opportunities, but there is an overwhelming amount of homework.
