- Jon’s early career was with British Telecom as a telecommunications engineer, technical trainer, training manager, management trainer and internal consultant. As an internal consultant he worked in collaboration with line managers to support the implementation of organisational change initiatives such as customer care and total quality management. In 1990 he left BT to work as an independent management and organisational development consultant, working with a variety of clients - mostly large organisations in IT and utilities - on issues of learning, development and change. He became a partner with Castleton Consulting in 1998, focusing since then on developing products and services based around creating the conditions for personal and organisational effectiveness. Jon has a somewhat intermittent interest in taking part in triathlons – he has entered the 2013 Hever Castle half-ironman event having last taken the plunge in the Windsor triathlon of 1999. Outside this punishing schedule his time is taken up with tending a vast collection of seashells he keeps on permanent display on beaches throughout the world.
