Diana Brotherston

Governor role: Chair of the Governing Body and Coombe Trustee

I am a community governor and I am the Chair of the Governing Body. I have 35 years experience as a teacher working in primary schools which includes 18 years as headteacher.   I retired in August 2012. My skills include leadership of teams of people and organisational skills together with knowledge of primary education and teaching. I am enjoying using my experience to contribute to the development of Knollmead Primary by working with the staff and local community to raise standards to create an outstanding school for the pupils. As part of my role I am link governor for Literacy, Science and MFL.

Lucy Philpot

Governor role:  Chair of Curriculum and Standards Committee.

I have been a governor for 18 months or so, and was a governor back in 2006-2008. My son is in year 4 at Knollmead and my daughter also went to Knollmead.

I worked at EMI in Logistics and Customer Service Management for 23 years, and more recently have been working as Admin Officer at Lime Tree primary school in Surbiton. My main experience is in personnel management, change management and dealing with customers and now parents, plus dealing with any adhoc situations as they arise! I want the children of Knollmead to have a happy, fulfilling school life and to learn and progress as much as they can to their best ability.

I am a community governor for Knollmead and have been a governor for 4 years. I am a Chartered Management Accountant by profession and am employed as a senior accountant at The Crown Estate, with responsibility for all the financial accounting processes. At The Crown Estate I am also leading a special project, working with two charities to provide work experience and mentoring for students from less advantaged backgrounds in the London area where we are major land owners. I am a Sri Lankan by birth but have spent nearly all my adult life in the U.K.  I have a large extended family who are now dotted around the globe. I am married with 3 grown up children and 2 grandchildren.  My 3 children all attended primary and secondary state schools in the Royal Borough of Kingston before going on to further education at leading universities. I love travelling, enjoy cooking and am a voracious reader.

Judith Davies


Governor role: Community Governor, Coombe Trustee.

On leaving university I became a teacher, then a housewife and mother.  I have three children and two grandchildren.  For the last 15 years of my career I worked for the Department for Education as a policy adviser to Ministers. I feel privileged to be able to contribute to the life chances of young people as a school governor.  I am also a volunteer adviser at Esher Citizens’ Advice Bureau. In my spare time I am a member of a local choir, enjoy creative crafts and take lessons in singing, piano and watercolours.

John Guinnard

I am an Internationally experienced financial controller, with responsibilities as Divisional Financial Director for part of a multi-national British based group of companies. Apart from finance, I have been responsible for office services, personnel, building maintenance, insurances and car fleets. Most of my spare time is taken up with bowls.  I am a director of a company that provides the facilities for King George Field Indoor Bowling Club in Jubilee Way, Chessington.  I play for Surrey both indoors and outdoors, and have won several district competitions. Apart from 2 years in Singapore, I have lived in the Tolworth area for all of my life. I used to be very active in Scouting, being a qualified Scout and Cub Scout Leader, and believe that every child should be encouraged to realise their full potential regardless of their background.

Mrs Margaret Hurrell

I have worked in child protection social work for 36 years and currently chair child protection conferences and deal with allegations of abuse against members of staff in many statutory agencies, such as health, education and social care. I enjoy writing, socialising, mince pie making and I am quite creative when given the opportunity. I am passionate about my faith, my family and my commitment to supporting children and families. I enjoy the cinema, reading and the theatre.

Karen Bridgman

Governor role: Clerk to the governing body

Lynn Hayes

Governor role: Community Governor, Vice Chair.

I was initially elected as a parent governor of Beverley Boys' School in the 1990s and subsequently took on further responsibility as Vice Chair, and then as Chair. As Chair, I saw the Boys' School through some of its toughest times.  I was very involved in steering it through a major and very difficult change in leadership, and then through its union with the Girls' School under the Coombe Federation.

I served on Pastoral and curriculum committees but also was responsible for chairing exclusion panels and staff competency panels. I was on the panel to appoint the new Head Teacher Debbie Walls leading and liaising with the student panel as they met with a variety of candidates.   I visited the schools regularly and was proud that I had good relationships with staff. My experiences throughout were interesting and at times challenging. I served as a Governor for 12 years and left at the end of my term when I no longer had children in the school. Both my sons attended the school and have subsequently gone on to university and the world of work.

I have been a teacher up until a few months ago when I decided to retire. I was latterly Head of Physical Education at Holy Cross Girls' School in New Malden. I have also been employed as a Behavioural Support teacher with Kingston.  I helped to deliver core curriculum to students who no longer attended school for one reason or another.

My hobbies are mainly sporting ones. I have recently represented GB at The World Age Group Triathlon Championships in Edmonton, Canada.
