I feel so lucky and grateful to have ZIS in my life. No matter how our children's new adventure unfolds, the Spier family will never leave ZIS. You can count on us as lifelong members and supporters.
My years as a student at the Wadenswil, Kilchberg and Adliswil campuses have firmly established the values of learning, caring and the importance of relentless challenge and leadership into my world view. Above all, it is my esteemed educators and peers with whom I have had the privilege of learning, that have defined my ZIS experience. An experience that has truly made ZIS my home and continually inspires me to grow as a gentleman and a scholar.
It has been a privilege being part of this community and the connections I have made with other educators, parents and children have been life shaping. ZIS has been a true home to not only myself but also for both my daughters who graduated from ZIS and have continued their learning in leading universities in Holland and Scotland. I could not have wished for a better place to be!
I am incredibly grateful that Andres has such an enriching and nurturing as well as stimulating school environment where he can learn and thrive. As a parent, the SGIS presentation is one I will not forget. It was very touching to see so many teachers who taught Andres since he was four years old attending the session.
In Grade 1, Mr. Clement began encouraging me to tinker and draw my invention ideas. In Grade 2, he taught me that I could create anything! Now that we’re in Atlanta, my family and I teach my class about science and engineering, and I speak at schools about girls in STEM. Thank you ZIS and Mr. Clement for helping start my tech journey!
We've been really impressed with the ZIS student interns we've had at Heptagon during the past two summers. They bring an enthusiasm to learn and also to share their skills and perspectives with us - so it's a two-way, win-win relationship.
ZISMeets have been amazing for reconnecting with old classmates as well as meeting new friends from the ZIS community. I feel like everyone who has spent any time at ZIS (or IPSZ as I knew it) are all connected by shared experiences and ZISMeets have brought us together to share stories and learn from each other.
