Senior Leadership Team
Ms Sophia Hardy
In 2020, Sophia made the transition into the independent sector, joining RMS as Deputy Head Academic.
After being educated in Hong Kong, Sophia began her teaching career at Glyn School in Surrey, an outstanding all-boys comprehensive school. In her six years at Glyn, she worked in pastoral roles as Assistant Head of House, Pupil Premium Coordinator, and led A-Level Geography. Sophia then moved to Wilson’s School in Wallington as Head of Geography, later taking on roles as Deputy Safeguarding Lead and Teaching and Learning Lead.
Mrs Helen Roberts
Helen joined RMS in 2015 as Head of French and has since held a variety of pastoral and academic leadership roles, becoming Deputy Head (Leadership & Development) in January 2025 and leading on teaching and learning, digital strategy and staff professional development.
Helen was raised and educated in Cheshire before completing her BA in Modern Foreign Languages (French/German) at Durham University. After graduation, she spent a number of years working in a global management consulting firm which gave her the opportunity to work abroad and indulge her passion for foreign language and culture. Realising that she wanted to pursue a career in education, Helen returned to the UK to complete her PGCE and has since gained extensive experience in both the state and independent sectors. Aside from the joy of working with fabulous young people, what excites Helen most about working in education is the constant opportunity for learning and growth – there is never a dull day!
Outside of school Helen enjoys spending time with her family and friends and making the most of all that living in the Chilterns has to offer.
Ms Alison Davies
Alison joined in 2021 as Deputy Head Pastoral having gained considerable expertise in this area of education over the previous 13 years at her former school. Since being at RMS, she has spearheaded the relational ethos of the RMS using the latest research and strategies for the benefit of all pupils and the RMS community.
A native Brummie, Alison spent her formative years in Birmingham before heading to the sunny south coast to live and teach history in both the independent and state sectors before relocating to Hertfordshire.
Despite her role now being predominantly pastoral and safeguarding focused, Alison remains a passionate historian who is always ready to pass on a quirky historical fact which, whilst interesting, is often of little use!
A keen gym goer and fitness enthusiast, Alison has completed a few marathons and half marathons and enjoys taking her dogs on long walks around the River Chess and Grand Union Canal.

Mrs Emma Taker
Emma joined RMS for Girls as Director of Marketing and Admissions in March 2023. Raised in Kent, she completed a BSc (Hons) in Business Studies & French before beginning her career overseas in tour operating.
After returning to the UK to raise her three children, she discovered the vibrant world of independent education and has been dedicated to the sector ever since.
Emma felt a special connection to RMS for Girls, as her mother was a full boarder at the school during the 1950s and 1960s. Deeply passionate about independent education, Emma is steadfastly committed to championing the extraordinary, life-changing opportunities it delivers to students.
Outside of school, Emma loves spending quality time with her growing family, making the most of living so close to London, and taking long walks with her energetic Newfoundland dogs.

She has held roles in capital development project teams at the MoD and the Department of Energy and Climate Change. She is particularly passionate about ensuring that the financial, estate development and operational decisions support pupil engagement and growth.
Outside of school, Emma has three older children and enjoys spending time with her family visiting restaurants and taking trips to the theatre.
Mrs Alina Ghioc
Alina joined RMS in early 2022, bringing extensive experience from independent schools across Hertfordshire. Born and educated in Romania, she earned her Bachelor’s degree in Economics and Business Law from The Bucharest Academy of Economic Studies.
After moving to London in 2003, Alina specialised in Human Resources, working across several industries before transitioning into the education sector.
She approaches HR with integrity, upholding standards while treating every team member with fairness and genuine care. Outside of work, Alina enjoys long walks with friends, traveling, and spending time with her family (which mostly means playing chauffeur for her two sport-loving teenage daughters).
