Current Governors

Mrs Sarah Mortimer 

Chair of Board of Governors (Co-opted Governor)


Term: 09/11/2015 to 08/11/2019 

I have been a Governor at Garth Hill College since 2011 (and was previously a Chair of Governors at an infant and junior school). From September 2019 I am picking up the reins from Liz Dolby as Chair of the Board and aim to build on all she has achieved in strengthening governance as we continue in our journey of improvement for the benefit of all pupils.

I enjoy having first-hand knowledge of the school so that I can celebrate the commitment and success of pupils and staff and work with them, parents and governors to make Garth Hill College an excellent school community; it’s a privilege.

I joined the Board of Governors because I care about education.  I wanted to support the school that all three of my children moved into at age 11. I was impressed with the provision they enjoyed here and they have now gone on to university and employment.

I have a language degree and qualified as a teacher in the Further Education sector where I also trained in literacy teaching and supporting learners with special educational needs. This background in education helps me in my role as governor.

I bring enthusiasm and commitment to the role, along with a belief that all young people have the right to an excellent education in their local school.


Mr Andrew Lebrecht

Vice Chair of Board of Governors (Co-opted Governor)


Term :  27.01.2016 – 26.01.2020

Committees: Chair of Pay Committee and  Principal’s Performance Management Committee

Post Ofsted Action Plan: Chair of Governors’ Scrutiny Panel

Link Governor: Science and Technology and Brownlow House and Deputy Link Governor for Business (Finance and IT)

I have been a Governor since early 2016.

I became a Governor at Garth Hill College because I wanted to offer the expertise I have as a former civil servant and diplomat to the benefit of the local community. Serving on Garth Hill’s Board of Governors is an ideal way of doing this and I hope I can add real value to the Board.

I enjoy the enthusiasm and positive spirit I find everywhere at Garth Hill. I enjoy working with a college that is well led and well governed but nevertheless faces many challenges to ensure it provides the very best for Bracknell children and the local community over the coming years. I have recently come to live in Bracknell, having spent most of my adult life living in Reading. I have 2 daughters who benefited from excellent State education and are now pursuing interesting careers.

I developed the skills I hope to offer Garth Hill through senior leadership roles in the Department of Environment in London and the UK permanent representation to the EU in Brussels.

Mr Keith Grainger

Ex Officio Governor (The Principal)


Term:  Continuous

I have been a Governor at Garth Hill College since 2007.

I became an Ex Officio Governor upon my appointment as Principal of Garth Hill College.

I sit on all of the Governing Body committees.

As Principal and Governor, I enjoy working with a wide range of people to provide the best possible educational experience to all of our young people.

I graduated with an Honours degree in Social Science in 1991, and then completed a PGCE course in History, gaining distinction in practice.  I began teaching in 1992.  I have a Master’s degree in Education Management and attained the National Professional Qualification for Headship.  I have been working for Garth Hill College since 2001 and have been Principal since 2007.  I have extensive experience of working with many other secondary schools (former PIXL Club Associate and Chair of the Bracknell Forest Secondary Headteachers’ Group).  I sit on the Local Safeguarding Children Board and Bracknell Forest Schools’ Forum.  I am also a primary school governor.  I am married with three children.  My interests outside of education include music, military history and Chelsea Football Club.


Dr Gareth Barnard

Local Authority Governor


I became a Governor at Garth Hill College because I wanted to support our local secondary school as it embarked on a sustained journey of school improvement and to help it meet the aspirations of the young people that attend and the wider community it serves by putting students at the heart of all that the college does. I enjoy meeting the students, sharing their successes, both inside and outside of the College.

I also enjoy watching Garth Hill College grow in confidence, as a truly inclusive school, serving the communities that make up the greater North Bracknell area. I have lived in Whitegrove, Warfield since 1991 and have three children, one attending a local secondary school. I am an Elected Borough, Town and Parish Councillor, with, on the Borough Council, responsibility for School improvement and more widely services for Children and Young People. 

I have a background in science, as a chemistry graduate with a PhD from the University of Leeds. I bring an understanding of the School improvement framework, public accountability, knowledge and understanding of science teaching and enthusiasm to serve the wider Garth Hill College community. 


Term: 01/02/2018 to 31/01/2022

Post Ofsted Action Plan: Behaviour, Personal Development and Welfare

Link Governor: Pupil Personal Development, Behaviour and Wellbeing (including Trips and Visits)

Mrs Rebecca de Bruin

Staff Governor

Term:  01/09/2019 – 31/08/2023

Link Governor:  Development

I took up my post as Staff Governor in September 2019, but was a governor at my previous school for 2.5 years before moving to Berkshire in 2017. 

I think it's really important that governing bodies have staff members, particularly teaching staff, who can help them to have a realistic view of what life is like within the school. Having worked at Garth Hill College since 2017 I felt ready to take on a further roll that would allow me to give back to the College. I enjoyed being a staff governor at my previous school, and felt that this was a way I could help the College to be more successful. 

I graduated with a First Class Honours degree from the University of Oxford in 2008. After a brief foray into independent schools, I completed my PhD at the University of Bristol. I gained my QTS by training through the Teach First Leadership Development Programme, which places participants in schools with a Pupil Premium intake of over 50%, and remained working in this context after I finished the programme. In 2017, I relocated to Berkshire, and began working at Garth Hill College, where I am Head of Chemistry and Second in Charge of Science. My interests outside of education are almost exclusively musical: I direct, sing in and judge choirs; and perform regularly with my barbershop quartet, Avalon. 


Dr Tijana Blanusa

Parent Governor


Post Ofsted Action Plan: Curriculum and Assessment

Link Governor: Maths, Information Studies and Fielden House

I became a Governor at Garth Hill College because I was eager to give back to the College which provides my two sons with a happy and overall very positive experience of secondary school education. I came to this role with six years’ experience of primary school governance and with a day job as a research scientist and a lecturer in the higher education setting.

My particular interests are in ensuring the quality of Teaching and Learning, along with the analysis of pupil progress data. I am a Link governor for the School of Mathematics and Information Sciences (Fielden). I interact regularly with teachers and school leaders to understand key priorities and day-to-day activities within the school and to offer challenge and support. The most rewarding part of my role are meetings with pupil representatives. Their fresh and honest views remind me why we are here!


Mr Michael Giles

Parent Governor


Term: 23/09/2018 to 23/09/2022

Link Governor: Environment

Seven years ago after a long career managing high volume printing, information technology and graphics arts I set up a business offering a complete maintenance solution to prestige properties. During this time, I have worked with many ex pupils of Garth Hill College within the local trades as well as young people starting out in their first year of full time work.

It has given me a unique understanding of local needs within the community and the needs of local business. 

The skills I can bring are one of seeing opportunities when they arise, understanding issues and contributing to achieve good outcomes, an ability to listen and work with people both young and old, build positive relationships and bring fresh ideas. 

Having worked in the corporate marketing world within the services industry and also setting up a local business I have gained a number of skills and can offer advice when required in areas of negotiation, research, project management and starting a business. Having a daughter at Garth Hill I see both sides of the issues and have a vested interest in the college improving positively in the near future. 

The college is clearly going through a period of change and I would like to help in any way possible to ensure it improves for the benefit of both pupils and staff at this challenging time.


Mr Brian Poxon

Parent Governor


Term: 24/01/2019 to 23/01/2023

Committees: Pay Committee

Deputy Link Governor: Pupil Premium, RISE, SEN and G&T

I first became a governor in November 2011 when I joined Sandy Lane Primary School as a parent governor. My son is now at Garth Hill which prompted me to join the governing body in 2019. During my time as governor at Sandy Lane I have been involved in two Ofsted inspections and two HMI visits. I have also been a member of the Head Teacher’s performance committee, pay committee, chaired the full governing board meetings and the Resources Committee and have participated in numerous learning walks and local authority training. I have also studied the chairs development programme run by the National College for Teaching and Leadership.  Finally, I am a member of Schools Forum and the Governor Services Reference Group.

At Garth Hill, I am currently a member of the governor disciplinary committee, pay committee and link governor for RISE and Pupil Premium.

I became a governor because I am passionate about improving our children’s education and supporting Garth Hill on its journey to Good and beyond. The governors and staff have struck me as dedicated professionals who want the best for our young people and its inspiring working with such passionate individuals. There is so much potential within the staff and pupils at Garth and it’s exciting being part of such a dynamic team.

I have an Economics degree and have just finished studying for a master’s degree in Psychology of Work. In my paid job I am a recruiter and specialising in placing senior finance professionals with clients in the Thames Valley and London.

Mr John Garred

Co-opted Governor


Term:  24/09/2015 to 23/09/2019

Post Ofsted Action Plan:  Pupil and Parent/ Carer Voice

Link Governor:  Business (Finance)

I was elected to the Board of Governors in September 2015.

I became a Governor at Garth Hill College because I wanted to broaden my understanding of secondary education with a view to using my business experience to provide guidance and advice that could ultimately assist pupils in determining their career paths.

I am a Chartered Accountant with over 30 years’ experience of working in multi-national companies across various industry sectors e.g. airline, retail, service, manufacturing and engineering.  In recent years my focus has been on compliance and ethics, particularly relating to global corruption.

I am married with two children currently at Garth Hill College and I previously served on their Primary School PTA for nine years, two as Chairman, and one as Vice-Chairman.  I also coached a local junior football team for four years and obtained the Football Association’s level one coaching certificate.


Mr Charles Jenkins

Co-opted Governor

Term: 11/06/2019- 10/06/2023

Link Governor: Safeguarding

Mr Chris Lomas

Co-opted Governor


Term : 11/09/2018 to 10/09/2022

Link Governor: IT and Attendance & Participation

I joined the Board of Governors in late 2018 because I have a strong interest in improving children’s educational outcomes and wanted to contribute to the local community. I have a son who is at the College and a daughter who is soon to join and I wanted to offer my assistance to the College that has supported my son so effectively. When the opportunity arose, becoming a governor at the College seemed the natural way to do this.

I have worked in IT for over 20 years, the last 15 of which have been in management positions, most recently at executive level. During this time, I have amassed a broad spectrum of experience in all areas of IT and project management supplemented by strong strategic thinking, vendor management and people management skills.

I believe that I am well positioned to use my skills and experience to provide support for the staff and pupils and to assist with the continual improvement and development of the College to drive forward positive change and to help make it an outstanding school.
