Chella Quint is a Brooklyn-born, Sheffield-based designer, writer, and performer. A former drama teacher and head of PSHE (Personal, Social, Health and Economics Education), Chella coined the phrase ‘period positive’ in 2006 and founded #periodpositive to use humour and joy to challenge menstrual taboos, and find long-term solutions to period poverty. She became a leading expert on menstruation education in the UK, advising on regional and national policy on menstruation education and period poverty. She created the Period Positive Pledge as a framework for developing menstruation-inclusive policy and outreach. Chella writes and performs solo shows, delivers public engagement projects and designs installations on themes inspired by science, health, taboo, product design and social justice.
