  Deputy Head - Pastoral and Boarding

  I always remind our students that they are valued because they are unique and that as such, our school is a different place because they are here with us.

  Deputy Head - Pastoral and Boarding

  Aodain Clover

  I have always felt very lucky to work in a school where the girls and staff value what the school stands for so much. They don't necessarily know it when they arrive, but they certainly understand it when they take it into the world with them at the age of 18. I feel that there is something almost undefinable about our community which is fundamental to what makes us different.

  Aodain Clover is the Pastoral Deputy Head at St Marys Senior School. What that means on a day-to-day basis is that Aodain looks after girls with the help and guidance of a wonderful team of tutors, Heads of Year and dedicated support staff such as the nurses and counsellors.

  Aodain first joined the school’s RE department 21 years ago and since that time has been Head of Years 7, 11 and our Sixth Form before becoming Pastoral Deputy Head. This means she is in charge of everything from attendance and punctuality, to uniform and discipline through our dedicated and keen staff. She is also the Senior School's Designated Safeguarding Lead to ensure the staff and girls are aware of important matters surrounding safegu​arding issues. 

  Aodain says she always felt as if she was coming home, when she first arrived here in 1998 because she had first met St Mary's girls when she was 16 on her very first trip to volunteer in Lourdes when many of them became her friends. To then come to work in a community which values each individual in the way we try to do, is really important for her as a teacher, she says.

  Acting Head of Juniors

  I was the Head of Juniors here at St Mary’s around eight and half years ago, therefore, many of the structural aspects of the school, the fittings and fixtures, remain so familiar. It has been a delight to reacquaint myself with colleagues from my previous tenure and meet the newer members of the teaching and learning assistant team.
