From the Classroom to the Stage
In 2003, George Marti, a young student with a love for music, joined ISZL in Grade 3. His journey would eventually take him from a Swiss classroom to stages around the world. Despite facing the challenge of being visually impaired, George’s musical talent shone brightly. Guided by his perfect pitch, remarkable memory, and the encouragement of teachers Lynne Holian and Missy Malcarny, George embraced his love of music.
Our community spirit is at the heart of everything we do. It shapes our events, inspires connections, and builds a strong sense of belonging. From alumni reunions to back-to-school nights, our recent start-of-term events have helped build a strong, inclusive and supportive ISZL community.
Join ISZL students as they explore practical mathematics in the Sihlwald Forest and learn about their unique outdoor maths lessons on our latest podcast episode.
When the Gaillet family set foot in Switzerland in September 2004, they planned a three-year adventure. Little did they know, the International School of Zug and Luzern (ISZL) would become a cornerstone of their lives, transforming a short stay into a 20-year journey filled with growth, learning, and memories
Last week over 900 students from around the world converged on our High School campus for the Seventh Youth Forum Switzerland.YFS was inspired by the Open Forum in Davos in 2017. Now in 2024 students from neighbouring international and local schools plus students from the United States, Romania, and Germany come to hear speakers including Paralympians, environmental activists and Timothy Cho, a two-time defector from North Korea.
As an international school in Switzerland, we help students turn their learning into action, creating the opportunity to stretch themselves further and achieve more than they believe possible.
Our vibrant, multicultural and caring community fosters a deep sense of well-being.
