Meynell is a playworker, playwork trainer and lecturer, and playwork advocate. He has been working with children and young people in various capacities for 51 years. An MPhil and qualifications in teaching, youth work, playwork, and expertise in the early years have given him a very clear understanding of the role of play and its importance in the everyday lives of children. He travels extensively across the globe to discuss play and playwork with both face-to-face workers and academics. He is still a frontline playworker both with Meynell Games and also as the Playground manager at Hastings Adventure Playground, as well as an academic, and his role in curating a specialist collection of play, playwork, and childhood books for sale enables him to be one of the most well-read in the sector.
