Horizon English School Town Square, the highly anticipated new all-through British curriculum school set to open in Dubai, is delighted to announce the appointment of two distinguished educators to its founding leadership team: Charlotte Grieves as Head of Primary and Lewis Hammill as Head of Secondary.

These appointments bring together two highly accomplished school leaders, each with a proven record of delivering strong outcomes and sustained improvement, cultivating high-performing teams, and shaping purposeful, inclusive school cultures. Their combined expertise ensures the school will open with both clarity of vision and the leadership depth required to deliver an exceptional educational experience from day one.

Charlotte Grieves joins with over two decades of experience in education, including extensive senior leadership roles across leading British curriculum schools in the UAE. Currently serving as Head of Prep at Cognita’s Royal Grammar School Guildford Dubai, she has played a pivotal role in the school’s formative years, contributing to impressive inspection outcomes, whilst helping to establish a strong culture and solid academic foundations.

Her career also includes senior roles within established school groups in Dubai, including serving as Interim Principal with responsibility for whole-school leadership. With over 15 years’ experience in the UAE and involvement in more than ten inspection cycles, she brings a sophisticated understanding of school improvement, curriculum design and inspection readiness.

Commenting on her appointment, Charlotte Grieves said: “It is a privilege to join the team at Horizon English School Town Square at such an exciting time. I want to work together to build a primary environment where children feel safe, motivated and genuinely supported, one where high expectations go hand in hand with kindness, and every child has the chance to flourish.”

Alongside Charlotte, Lewis Hammill is appointed as Head of Secondary with 14 years of experience in education, including a decade in senior leadership roles across both the UK and UAE. He joins from a leading British curriculum school in Dubai, where, as Deputy Head of Secondary, he has played a central role in driving sustained improvement and strengthening both academic outcomes and the systems that support teaching and learning.

His work has contributed to strong inspection results and measurable gains in student achievement, including GCSE outcomes placing within the top 1% nationally and A Level performance within the top 10%, benchmarked against international standards. He brings particular strength in assessment strategy, curriculum development and leadership capacity-building, underpinned by a clear, evidence-informed approach.

Speaking to his new role, Lewis Hammill said: “The opportunity to help shape a secondary school from its inception is both exciting and genuinely meaningful. Our focus will be on establishing a culture defined by high expectations, strong relationships and a clear sense of purpose, ensuring students are well prepared for both academic success and life beyond school.”

Together, Charlotte and Lewis offer complementary expertise across primary and secondary education, enabling a coherent and carefully aligned all-through experience that supports students at every stage of their development, while providing reassurance and continuity for families.

Nick Hart, Principal of Horizon English School Town Square, shared: “For families, the quality of leadership is fundamental. Charlotte and Lewis are both exceptional in their fields, bringing not only experience, but sound judgement, integrity and a clear commitment to delivering the very best for every child. Their appointment ensures that our school will open with both strength and purpose.”

Building on Horizon English School’s 35-year legacy, the Town Square campus will offer a well-rounded British education within a connected and inclusive community, where every child is supported to grow with confidence, achieve highly, and develop a strong sense of self, enhanced by 1,260 sqm of premium sports and arts facilities accessible to both students and the wider Town Square community, alongside a Design & Innovation Hub that fosters hands on, interdisciplinary learning and real world problem solving.
