A natural educator, Mogg knew fundamentally that her philosophy and ideas were focused on nurturing children´s development and broadening their learning experiences and she wanted to be able to put them into practice. In 1978 she and her husband, Evan Hercules, bought number 8 Dallington Street, the former site of the Gatehouse School, and Dallington School was born.
Teaching mixed ages in one room, Mogg´s unusual approach to teaching and learning soon attracted parents who wanted something a bit different for their children: parents who wanted to allow their children to become independent and curious learners; children who could think for themselves; who were given the chance to explore their interests and who would develop exceptional collaborative and social skills and be able to debate intelligently; to be kind, self-aware and aware of others.
