hanahau‘oli is Joyous Work
Hanahau‘oli School nurtures life-long learners – children, teachers, and parents. Since the school’s founding in 1918, Hanahau‘oli honors the natural way Junior Kindergarten - 6th Grade children learn – through doing – by making learning exciting, challenging and enjoyable. Our intimate and nurturing learning community supports connections between home and school and the world, respecting and celebrating the uniqueness of the Hanahau‘oli child while appreciating the interconnectedness that defines our learning ‘ohana. Grounded in tradition yet embracing of innovation, we perpetuate “joyous work,” committed to being a resource and symbol of learning’s potential.
You've probably used an app I helped build. I co-founded Google Street View and led product design at Uber Eats. More recently I spent three years building an AI startup called Cove, until our team was hired into Microsoft. Two decades of that work taught me what thoughtful software can feel like. Plenty of software for grownups is awful, but the industry has at least proven that software can be powerful, elegant, and humane: maps that help us understand a city, tools that let teams collaborate across continents, creative apps that let an amateur make something that used to require a professional.
Over the years, I have had the ultimate pleasure of getting to know Dr. Alfred L. Castle. Al is a historian, author, and the Executive Director of the Samuel N. and Mary Castle Foundation. The mission of the Foundation is to provide resources that improve the lives of Hawaii’s children and families, especially the quality and quantity of early education. The Samuel N. and Mary Castle Foundation concentrates its efforts on creating greater social equality and opportunity through increasing access to high quality pre-K education, and since its inception has been deeply invested in growing the American progressive education movement in Hawai‘i and beyond.
