In addition to what has been noted above at 5. I have been a main trainer in mediation for many ADR organisations, legal institutions, judicial commissions and academic institutions. In respect to my training. My first course in which I enrolled to become a mediator was with CDR Boulder Colorado and LEADR (Lawyers Engaged in Alternative Dispute Resolution) which was arranged by the Law Society of NSW and the Supreme Court of NSW for the establishment of the Supreme Court First Settlement Week in NSW in 1990. I also trained with the Australian Disputes Centre (ADC), Peter Adler (Hawaii Supreme Court) with ADC on environmental dispute resolution, also a course on transformative mediation, the Harvard negotiation course and mediation course and as noted above I was sponsored by Harvard Law School to teach with Professor Sander and wrote the 1990’s manual for Teaching Assistants for the mediation course for Professor Sander. I continually lecture on various aspects of ADR and Mediation. In 2021, examples of lectures I presented include: Mediation in Intellectual Property Disputes (IBA Mediation and Intellectual Property Committees), Mediating Medical Disputes (Asian International Arbitration Centre, Malaysia), Mediation in the South Pacific (Fiji Law Society), ADR Regulation (Association Européenne Des Advocats sponsored by the European Association of Lawyers European Union and Council of Europe), and Cultural and Ethical Issues in Mediation (Catholic University of Portugal) amongst many others
