Saddeea Gill
Founder, author and linguist
«Language is movement, sound, encounter – not just grammar. As the founder of hello gill, I develop learning spaces where people can learn to speak German with joy and ease – with minimal grammar and maximum relevance to real life.
My vision is to teach language through experience: outdoors in nature, in conversation with real people, embedded in Swiss culture. With Seven to Seven, we are taking this vision to a new level – lively, immersive and radically human.»
