Meet the Senior Leadership Team

Mark Sheridan -  Headteacher

I am extremely proud to be the Headteacher of Tanbridge House school. Prior to this, I was Deputy Headteacher at Tanbridge for 9 years.

Building on strong foundations rooted in our core values of Care, Kindness and Achievement we have seen the Tanbridge Community go from strength to strength. I am very fortunate to be supported by an outstanding Senior Leadership Team who embody our school vision and values on a day to day basis.

 We share the same goals for students and staff to be ambitious for themselves and be the “best that they can be”.

My background and passion beyond education has been firmly rooted in sports and reinforces my belief that all young people should have the opportunity and be encouraged to enrich their school experience beyond the taught curriculum, whether in sports, arts, creative or other academic outlets.

 Tanbridge House school is an inspiring place to work where young people never fail to amaze me with what they can achieve. 

Vicky Edwards - Deputy Headteacher

  I joined Tanbridge House School in September 2002, and, after a number of years as Assistant Headteacher, I was delighted to start my role as Deputy Headteacher in January 2013. In my role I am responsible for leading Teaching and Learning at THS, working closely with subject leaders to ensure effective teaching leads to students making excellent progress in lessons.

I studied Ecology at Imperial College, London University where I gained an upper second-class degree. I then completed my Post-Graduate Certificate in Education at Oxford Brookes University. 

Andy Ratcliffe - Deputy Headteacher

I joined Tanbridge House School as Deputy Headteacher in September 2022 and lead on staff appraisal and raising academic achievement.   I enjoy working closely with other senior colleagues and Leaders of Subject to ensure we are providing every opportunity for our students to achieve great GCSE outcomes and a successful pathway to Post 16 study. 

I still enjoy teaching history to all years and thoroughly endorse the school's values of 'Care, Kindness and Achievement', believing them to be a significant factor in the school's long standing academic success.

Away from school, I enjoy spending time with my family and playing sports such as tennis and golf.  

Jill Friese-Greene - Business Manager

I joined Tanbridge House in December 2003 having previously worked in the credit industry for a financial institution for 16 years.

As part of the Senior Management Team, my role involves leading the school in all non-teaching activities. This includes the school finances – setting and monitoring the budget and the school premises – including day to day running and developmental work.  I am also the school’s Health & Safety Officer. Additionally I run the Human Resources function for the school, dealing with recruitment, contractual and payroll issues. I also line manage the whole of the schools support staff.  I work very closely with the Headteacher and also with key Governors.

I am married, have two grown up sons, 3 grandchildren and two Labradors!

Nikki Kindon - Assistant Headteacher

I joined THS at the start of the 2015/2016 academic year having previously taught within East Sussex. I am really enjoying working in such a positive and successful school. My main leadership responsibilities are for data and attendance.

I teach Mathematics and am keen to enable all students to see how Mathematics is applied outside of the classroom.

In my spare time I enjoy sport playing hockey and running. 

Steve Loney - Assistant Headteacher

I joined THS at the start of the academic year 2015/16.  I had previously worked at Worthing High School where I was Head of Year and Assistant Headteacher.

My main leadership team responsibilities are for staff CPD, ensuring that teachers are supported in their efforts to deliver exceptional lessons for all students.

I teach French and German and I am passionate about promoting languages and the wider benefits that language learning brings.

Pete Marshallsay - Assistant Headteacher

I joined THS in September 2006 and greatly enjoy working here and being part of such a successful and thriving school. 

Since January 2015 my main responsibility is leading and overseeing the pastoral care and well-being of our students and supporting them in being as happy and successful as possible during their time at secondary school. My role, including being the Designated Safeguarding Lead, is integral to all we do at Tanbridge.

In addition, I oversee our Inclusion strategies, which includes our alternative provision for students for those students who attend college, as part of their studies, and those who need a more individualised curriculum. At all times, the focus is on the child and supporting them in their development, both academically and pastorally.

I began teaching in 1993 at Therfield School, Leatherhead, as a PE Teacher and gained promotion to Leader of PE at the Ashcombe School, Dorking in 1999.  In addition to my (now minimal!) PE teaching, I am a teacher of German and Business Studies.

Mark Osmond - Assistant Headteacher

I joined Tanbridge House School in 2004 as Assistant Leader of MFL, and subsequently became Leader of MFL and a member of the Extended Leadership Team, before joining the Senior Team in September 2015.

My role has a strong Teaching and Learning focus linked to assessment, and I will also be working closely with all stakeholders to improve our provision for all learners.

I studied French and Russian at the Universities of Sussex, Grenoble and Moscow, and gained an upper second class degree.

I have three children, in whom I am trying to instil a shared love of languages, chess and Nottingham Forest with limited success.
