Welcome to the Governors’ Page

St Christopher’s School Trust (Epsom) Limited is controlled by a board of Governors under the chairmanship of Mr D Roberts. The Governing Body oversees the external management of the School. The chair of Governors Mr Dominic Roberts can be contacted directly at

Comprising predominantly former parents, we have all enjoyed the experience of St Christopher’s so much that we have chosen to remain actively engaged, continuing our support and involvement of the school.

We know just how much work goes into achieving the academic outcomes, positive behaviour, and nurturing talent in the young children at St Christopher’s.

To find out more about each governor, you can view our individual profiles and look out for us at St Christopher’s events.

Thank you for your interest in the governance of St Christopher’s School.

Dominic Roberts – Chair and Chair of Finance Committee

I became Chair of Governors in June 2022 having been part of the school’s Board of Governors and chair of the finance committee since 2019.  I am a Chartered Accountant by background, having specialised in providing advice to Companies looking to access, or already listed, on the stock markets.   Nowadays I am the managing partner, responsible for setting and overseeing the strategic direction of the business, developing our team members, and promoting the wellbeing of our people.  

I’m lucky enough to be the father of two girls who were nurtured at St Christopher’s and both of these young St Christopher’s Alumni continue to cherish the friends and memories from their years at the school.  During my time as a St Christopher’s parent I witnessed first-hand the passion that the entire St Christopher’s team has for ensuring the best possible start for their young learners.  The team’s own commitment to excellence and continual development remains clear, whilst always placing the children’s needs first.  It is a privilege to be able to volunteer my time, along with the rest of our diverse and committed governing board, to the St Christopher’s community as we look to help ensure that the School continues to provide a wonderful start to the educational lives of your children in the years to come.

Helen Crossley – Deputy Chair, Academic & Curriculum, School Development, Bursaries and  Early Years Link

I became a governor in 2012 following my retirement as Head of Junior School at Ewell Castle. I previously held the post of Deputy Head of the Junior School at City of London Freemen’s School. I still work on a part-time basis, mentoring BA and PGCE student teachers when they are working in schools. I was the Chair of Governors from November 2016 to June 2021.

My role as a governor at St Christopher’s is especially concerned with curriculum matters, bursaries and school development.

It is a pleasure to be able to use the experience I gained, throughout my career, in a strategic role within such a high achieving school. A school in which everyone is working together to give an outstanding start to the journey through life for our young pupils.

Stephen Mainstone – IT

It was a great honour for me to be invited onto the Board of Governors in 2018. As a parent I felt hugely privileged to have been part of the St Christopher’s family for over 7 years. I have two daughters who both attended St Christopher’s from nursery through to Year 2; the youngest of whom departed in the summer of 2018. Both thoroughly enjoyed their time and therefore it is with great pleasure I now have the opportunity to continue that relationship and help the school moving forwards.

I am a Technologist with over 15 years experience in technology consulting and software development. I currently specialise in electronic trading automation for an investment bank.

I look forward to supporting the school with the same drive, dedication and enthusiasm that was given to my daughters during their wonderful journey at St Christopher’s.

Bryan O’Callaghan – Data, Finance and Bursaries

I was delighted to accept the invitation to join the school’s Board of Governors in 2019.

Originally hailing from Dublin, my wife and I chose Epsom as our home in 2006. Our daughter absolutely loved her time at St Christopher’s, thriving in its warm, productive environment until her departure in 2019. During this time, as a Class Representative for her year, I enjoyed liaising with the parents, the school and the PTA.

Professionally, I consult on business transformations across many industries (including professional services, new media, broadcasting, charities and environmental solutions) but primarily within financial services. These roles allow me to engage with people from Board level to new starters, improving their organisations – for the business, its staff and customers alike – through changes in operational process and technological advancements.

As Governor, my role covers finance and across the Board’s remit. It is my pleasure to work with the school’s wonderful team to further enhance the already outstanding experience enjoyed by the children and parents who join the St Christopher’s family.

Dawn Bhoma – Legal Matters

I have been honoured to serve as a governor at St Christopher’s school since 2019. My son and daughter both attended the school from the nursery through until Year 2 and the only negative was how quickly the time went. I feel extremely privileged that my children could thrive and enjoy so many varied experiences at such a young age. The ethos of the school in not applying limits to even the youngest children is admirable. I have therefore been delighted to stay connected with the unique St Christopher’s school community and do what I can to help.

I began my career as a lawyer at City law firms for 12 years before I left to join the insurance industry. I now run my own underwriting business which specialises in Mergers & Acquisitions.

My role as governor is to assist the school in navigating any legal issues or legal developments as they arise but also to help the school to evolve as all good schools should.

Elizabeth Hibbert –  Parent Communication, School Development

My St Christopher’s journey started in 2014 as a prospective parent attending my first Open Day. Since that date St Christopher’s  has continued to impress me with its exceptional standards across every area of school life. I became PTA Chair in 2017, which was a fantastic experience, enabling me to be closely involved in the school community and make a contribution. In 2019, I was delighted to receive an invitation to continue my association with the School as governor responsible for Marketing and the School Development Plan. I bring my knowledge as a parent together with my skills in marketing and communication to this role. Formerly an Agency Director in a leading recruitment communications agency, I am now a writer, with my own copywriting and marketing consultancy business.

I enjoy my continued involvement in a school which is truly special and has given our two girls such a wonderful start in life.

Dr Nadia Oozeerally – Child Protection & Safeguarding

I joined the Board of Governors in September 2021. The school, the staff, and its pupils, continue to delight and impress me whenever I can visit the school, and so I was delighted to accept the role when it was offered to me.

Both my daughters were fortunate to attend St Christopher’s from Nursery to Year 2, and we have many dear memories of their time spent there. The teaching staff put a great deal of effort into making the girl’s education varied and interesting, as well as offering a wide range of exciting extra-curricular activities, whilst maintaining a nurturing environment, which is so important for such young children. I truly believe the school provides a strong platform, educationally and emotionally, which more than adequately prepares children for their next journey.

I am honoured to be working alongside a truly talented and enthusiastic, highly skilled team which forms the current Board of Governors. My responsibilities include the important areas of Child Protection & Safeguarding. I draw on my 20 years of skills and experience working as a doctor in the NHS and since 2015 as co-director of a private GP practice locally.

I have welcomed the opportunity to contribute, in whatever capacity I can, in helping the school continue to provide the high standards of education and care, for current and future pupils at St Christopher’s.

Mark O’Halloran – Health & Safety, School Development

It was a great honour for me to be invited to join the Board of Governors in 2021.

My son and daughter were fortunate and privileged to attend St Christopher’s from Nursery through to Year 2. They both have great memories and thoroughly enjoyed their time, giving them a wonderful start to life.

I’m Managing Director of a small property development company. The day to day running of the business involves negotiating land and property deals whilst meeting our client’s needs.

Being invited to return as a Governor allows me the opportunity to give something back and to assist the school in any capacity that I can. My responsibilities included helping to manage the setting with a focus on Health and Safety.

Ciara Chellun – Marketing and School Development

As a parent of two St Christopher’s alumni, I have experienced not only the outstanding education the school offers but how the school nurtures and develops the different abilities and interests of children to become confident individuals. I was truly amazed at the number of ways my children were inspired to learn – from rockets landing in the school garden to trips to St. Pauls Cathedral – all testament to the fantastic team at St Christopher’s. It is no surprise that my children still talk about their time at the school with fondness and wonder, and I am grateful for the many happy memories they have from their time at the school.

My professional career has spanned retail and consultancy primarily in digital and marketing roles working for fantastic retailers like John Lewis and Pret a Manger. My most recent role was as a global head of digital product responsible for creating new digital propositions for Pret’s global markets. I also own a nursing home business with my husband while providing a busy taxi service for my children!

When the opportunity to become a governor arose I was more than happy to contribute my energy and experience to the ongoing success of the school. My role on the board is to support marketing and ongoing parent communication.
