'Jon and I have worked together in the same teams for various projects. He’s a great colleague. A real team player who is knowledgeable and supportive. He has a way of seeing things clearly so that everyone understands what is required for a piece of work, and all contributions are valued. We have both worked in the same county for a particular project and, the minute I mention knowing Jon, the teams that know him are full of praise for the support he has given them. And his sense of humour is legendary.'
