Educated at Charterhouse, St Edmund Hall, Oxford, and Henley Management College, his career began with teaching posts at the Royal Grammar School Guildford and Caterham School. He then spent a decade as Headmaster of Trinity School, Croydon, where he led a period of significant development.

After Trinity, Mark became Chief Executive of Perrett Laver, a global executive search firm, before returning to education as Executive Headmaster of YK Pao School in Shanghai.

Mark, who has also served as an independent schools' inspector, defines his educational philosophy as a "rigorous pursuit of excellence balanced by a compassionate concern for individuals," striving to stretch students' potential while building their self-confidence through encouragement and support.
