Marnie Rose Founder and CEO
After a career ranging from television production, advertising account handling in Borneo to agent for comedians and television personalities (Rowan Atkinson, Simon Amstell, Barry Humphries), it was Marnie’s work as a founder volunteer for King Henry’s Walk Garden in Islington, London in 2006 that led her to create The Garden Classroom.
Frustrated by juggling a young family with a meaningful work life and inspired by childhood visits to her Nan’s allotment plot in East London, regular visits to Wanstead Flats and Suntrap visits to Epping Forest, Marnie decided to tackle head on the lack of nature connection opportunities.
After meeting Founder Trustee Rosey Lyall and discussing the merits of the concept of the benefits of regular meaningful engagement with the natural world, together they set up The Garden Classroom as a new social enterprise for Londoners on 26th November 2008.
Since then it has become a multi-award winning charity which plays a key part in a national and global movement to encourage city children and young people to spend more time in natural environments.
