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.
