Having worked with John for over 20 years I knew him principally as a manager for both Naval and Land Programmes, where we worked closely together. Pulling on his experience, John was always willing to pass on advise and encouragement to both satisfy our customers and the aims of our company. We shared many interesting discussions when we needed to achieve a solution to issues that inevitably came up in our work. John was respected for his professional and friendly approach by both his customers and those who worked with him. It was great to work with you and I will miss you John, my thoughts are with your family.
