His experience over a 40-year consulting career has been primarily in the fields of strategic thinking, innovation and creativity, arbitration and conflict resolution, and ecologically sustainable development.  He has also been greatly influenced in his own thinking and practice as a consultant by a number of years spent early in his career in the Far East.

Typically he gets drawn into facilitating difficult conversations, supporting intelligent responses in complex circumstances, strategic judgement and personal coaching when the stakes are getting high.
