Marina Gardiner Legge
Marina Gardiner Legge
President 2023-2024
Headmistress, Oxford High School GDST

Born in India and schooled in North Borneo and Singapore, Marina Gardiner Legge was educated at a GSA school before going on to read English Language and Literature at Somerville College, which inspired a love of poetry that still burns brightly today. On completing her Oxford studies, she went on to work for a decade in advertising and marketing in London and Miami, before assuming the role of president at a charity based in Paris.

It wasn’t until she moved out to Hong Kong, several years later, that she discovered her passion for teaching and education, and made the decision to study for a PGCE. Moving back to the UK, certificate in hand, she joined Rutlish School as an English teacher, rising through the ranks to become Head of Year, Assistant Head and Head of Careers.

Following three years as Director of Studies at Heathfield School, Marina became Headmistress in 2016 and joined Oxford High School as Head in January 2021.

A passionate believer in the power of girls-only education to change lives, Marina has been described by those who have had the pleasure of working with her as fiercely intelligent and a very capable and caring educationalist.

Donna Stevens
Donna Stevens
Chief Executive

As GSA Chief Executive, Donna is responsible for working with Girls’ Schools Association members and other stakeholders to encourage high standards of education for girls and to promote the benefits of being taught in a largely girls-only environment. She took up her role in January 2021, at a critical time in the education sector, supporting GSA schools as they navigated their way through the ‘new normal’ which the Coronavirus public health crisis necessitated.
Donna Stevens was previously Head of Research for the Independent Schools Council, where she was responsible for overseeing a wide range of projects each year, such as the ISC Annual Census, the economic impact of independent schools on the UK economy and the impact of independent-state school partnerships. As a result of this, and her knowledge of the ISC’s other work, she has gained considerable insight to the issues surrounding the independent education sector and the role it plays within the UK education sector as a whole, as well as internationally. She is a regular speaker at education sector conferences.
Donna has also worked in strategic consultancy, advising across a wide range of sectors on financial matters, communication and brand strategies. In addition, she has experience in the social sector, working with organisations such as The Challenge and Action Tutoring. Donna has a degree in Mathematics from the University of Oxford, and a Postgraduate Diploma in Educational and Social Research from UCL. Outside of work, she owns and manages a successful performing arts weekend school which caters for 100 youngsters – including Donna’s own three children – and offers means-tested scholarships to local pupils. Donna also enjoys jogging and spending time with her family.
