A warm welcome from the Senior Leadership Team

The WGSB Senior Leadership Team, known as the SLT is made up of seven staff whom each possess their own specialist skills and experience but combine together to form a well balanced team with a shared ethos of personal care and academic excellence.

Mr Andy Williamson (Ma Ed., BSc, NPQH) - Headteacher

Mr Williamson joined Wilmington Grammar School for Boys in January 2010 having previously worked as the county’s Secondary School Advisor and in school leadership roles East Kent and inner London. Mr Williamson is currently a Local Leader of Education and a steering group member for the Dartford School’s consortium. Working in a school with an Engineering specialism matches his love for mechanics, and in particular motorsport, whilst three school aged children and the occasional round of golf keep him busy at home.


Mrs Denise Jackman (M.A English) – Deputy Headteacher, Learning Experience

Mrs Jackman has the very important role of leading and monitoring the pedagogy that takes place in lessons and helping develop student’s learning and progress inside and outside of the classroom. An excellent English teacher, she is also responsible for overseeing students in Years 10 and 11.

With a vast knowledge and understanding of the transition from Year 11 through Post 16 Education into University or career employment, Mr Sexton is in charge of the school’s Sixth Form. The continual growth of the Sixth Form over the last five years to over 200 students is recognition itself of his talents and in the February half term, without fail, Mr Sexton can be found stylishly speeding down the ski slopes of Europe or America.

Mr Mark Baker (BSc (Hons) in Sports Science) – Assistant Headteacher - Head of Upper School
