Jo qualified in 1982 as a Montessori teacher and taught for several years in Chelsea and Fulham before moving to France with her husband David to raise their young family. They returned in 1995, sending Katie, Harry and Jack to Cumnor. In 1995 Jo started working at Cumnor and is now in her tenth year. Her favourite age group is 4 to 5 years because it is such a pleasure to watch and teach children in a year which is so important to their future development. David and Jo split their time between family in the UK and their house near Perigueux in France.
