Trustees

Sarah Beagley has been the Headteacher of Elizabeth Garrett Anderson School since 2018. She joined the school in 1995 and has held roles in performing arts as well as leadership. She led the school to its fourth consecutive OFSTED Outstanding in 2025, one of only a handful of schools who hold this distinction. She is highly ambitious for the success of all students and determined to address social inequalities which prevent young people from reaching their potential. Sarah has a passion for arts education and has developed longstanding and successful partnerships with The Almeida Theatre and Sadlers Wells as well as The Guildhall School of Music and Drama who established their North London Hub at EGA in 2022. She is also a member of Music Education Islington’s Governance group working to ensure a fair and equitable arts offer for students across Islington.

David Shemoon has been Deputy Headteacher at Elizabeth Garrett Anderson School since 2019. An award-winning senior leader, he was recognised for his impact during the Covid-19 pandemic, particularly in remote learning and community support. During his time at EGA, he chaired the London Schools ICT Partnership and now chairs the Senior Leaders Network in Islington, playing an active role in supporting collaboration across local schools. David brings a strong background in teaching and school governance, having served as Head of Mathematics in two London schools and as a school governor at an academy in Kent for over four years. Before working in education, he led a team that successfully raised over £100,000 for an international children’s charity, an experience that continues to inform his commitment to social justice and community engagement. His work is driven by a belief in the transformative power of education and a dedication to ensuring all young people thrive.
