He has advised organisations on billion dollar negotiations, coached hundreds of executives across 43 countries, and contracted his services to a dozen specialised negotiation service providers. He has taught over 400 in-person negotiation programs for 13,000 participants, including senior executive leadership across business, NGOs, academia, government, judiciary, military and law-enforcement. His negotiation programs have been selected by leading academic institutions and military academies in 14 countries across the Americas, Europe, Middle East, Asia and Oceania.
