The Friends of Dulwich Prep London is a society for all parents and staff of the school. It organises various events throughout the year to encourage co-operation and good relations between the parents, the staff and all others associated with the school; and strengthen links between the school and the local community.
Any profits made from the various events that the Friends organise throughout the year are donated to the school to purchase equipment or to fund projects or donated to various charities chosen by the Friends, the boys or the school.
