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.
