John is an IB convert; his belief in the value of education it brings to students and teachers is firm. It brings holistic education to students that are transferable to any context, and builds in them the profile of a person that can be recognised by anyone, anywhere as lifelong learners. This firm belief comes from his multicultural background, spanning across the UK, South Korea, New Zealand and Australia, and professional experience in the financial/management sector. He has been exposed to different environments and continuous learning all his life; being able to transfer knowledge and skills from one context to another was, and still is, so enriching. To be able to provide and receive such education of diversity and excellence at many different school settings is his dream, and International Baccalaureate has allowed him to achieve this dream. John has worked in IB World Schools throughout his career, and has taught multiple MYP and DP subjects in groups 3 and 4. He has also served as a CAS Coordinator for a number of years, before moving on to his role as a DP Coordinator and the Head of Faculty for IB Secondary Science. John feels it would be a privilege to be able to add to the collective voice of IB Australasia, and bring fresh ideas to discussion from his experience and connections, to enrich the IB experience of students and staff in schools in our region.
