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.

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.

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

Jill Friese-Greene - Head of ResourcesI 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!

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

Mark Osmond - Assistant HeadteacherI 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 instill a shared love of languages, chess and Nottingham Forest with limited success.

Hannah Simon - Assistant Headteacher

 I joined THS at the start of the 2020/2021 academic year as Assistant Head having previously worked as a teacher and senior leader across both East and West Sussex. I am thrilled to be working in such a thriving and caring community with such an emphasis on kindness, care and achievement.

 My current senior leadership responsibilities are line management of PSHE, Psychology, FPT, and Child Development as well as Most Able and Equalities.

As a teacher for 20 years and a senior leader for 10, this is the third senior leadership role that I have undertaken; I have been lucky enough to work across several schools in East and West Sussex and Oxfordshire. However, as an English teacher, my passion will always lie with teaching Literature to young people.

 Time at home is spent relaxing with my therapy dog Chicken, as we explore the beauty of the Sussex countryside.
