AP's True Masterclasses
Jules Chappell OBE

Jules Chappell OBE served as Britain’s Ambassador to Guatemala, Honduras and El Salvador and worked on the GREAT Britain Campaign, promoting British business, tourism and culture across the world. Julie has won a Woman of the Future award.  In 2014 she left the FCO and became a partner at Hawthorn Advisors and then Managing Director, Business, at London and Partners, the official promotional agency for London.

The Ambassador Partnership’s True Masterclasses share the techniques and insights of successful leaders all of whom are former senior diplomats with a wealth of high-level international experience.

Masterclasses are highly interactive, providing workshop participants with sufficient theory to offer an intellectual scaffold and share real-life experiences relevant to the subject.  Participants practice the techniques learned in hands-on exercises, specially written for the programme.  Feedback is provided in real time.

Our team have tackled complex international problems at the highest levels of government.  They share that experience through Masterclasses in negotiating, communicating and problem-solving.

Our Masterclasses are organised around bold presentations and realistic case studies / roleplays that encourage participants to analyse the problems and issues in a deeper way, and then use subtle skills drawn from professional mediation techniques to make progress. What’s going on here? What’s this problem about?
