Mrs Mary Breen
Mrs Danuta Staunton
Headmistress Elect



Welcome to the website of St Mary's School Ascot. We are a leading Roman Catholic boarding school for girls aged between 11 and 18 years. We are a forty minute journey from London, and are set in 55 acres of beautiful grounds in the heart of Berkshire. We are a friendly, stable and caring community, proud of our academic and extra-curricular achievements and dedicated to bringing out the full potential of each of our 380 pupils.
This is my twentieth year as Headmistress of St Mary's, having been appointed in January 1999, and I retire from my post in July 2019. I am delighted to hand over the role of Headmistress to Mrs Danuta Staunton who has been at St Mary's since 2010. We are working very closely together this year and we will be very pleased to welcome you to St Mary's at one of our Open Days and to show you our school and introduce you to some of our pupils.

Mary Breen, Headmistress
