The Head Mistress of The Lady Eleanor Holles School is Mrs Gillian Low. Mrs Low was born in Wales, but grew up in Stanmore, in North London, where she was educated at a state primary school before gaining a free 11+ place at The North London Collegiate School in Edgware under the direct grant scheme. She went on from there, with an Open Scholarship, to read English at Somerville College, Oxford.
