Sarah Crowther was born and grew up in Sherborne, boarding at Leweston while her parents worked in local Sherborne schools. She loved the breadth of education that Leweston offered and continued with her interests in sports, music and drama when she went to the University of Manchester to study geography.

Her career started in retail, working in merchandising in large high street fashion retailers but evolved into the role of Managing Director of a start-up beauty retailer which was subsequently purchased by a US private equity company. Subsequent to this, Sarah ran her own business, advising premium beauty brands on their international expansion. In 2015, she changed career, completed a PGCE and retrained as a primary school teacher. She is currently on the senior management team of an outstanding London junior school. Sarah lives in Surrey with her husband and two teenage sons but regularly visits Dorset to see her family and friends.
