Senior Leadership Team

The College’s ethos is to nurture and educate our students to the best of their ability, supported by strong friendships in a community of faith and scholarship.

Motivated by a deep commitment to nurture and educate all our students, and to support and encourage our staff, the Senior Leadership Team (SLT) led by Robin Dyer (Head) sets out and implements the strategic vision for the College and for St Martin's Ampleforth.

Guided by a shared vision, the SLT is focused on delivering the present and long-term success of the College.  We actively seek to learn and grow together, ensuring a high level of trust, transparency and support. We set the pace and tone for the wider staff body, building confidence and cooperation, whilst seeking to ensure accountability. We place the nurturing and education of our students at the core of our priorities.

The SLT oversees the management of the College, both academically and pastorally, and ensures the ethos permeates everything we do.  Appropriate teams lead in each area.  The SLT works closely with the St Laurence Education Trust, the governing body responsible for the financial, educational and strategic management of the school.

Robin Dyer

After 17 years of school leadership and 33 years of teaching, the plan to retire to Cornwall and the South of France was appealing. The plan, when implemented, lasted only two days. Why? The answer is simple: I was lucky enough to be asked to be the Head of this wonderful school; when the offer was made it was, as they say, a 'no brainer'. It is an opportunity I approach with enormous excitement.
