“It was a revelation to work with people who are able to call a spade by its proper name and could actually help us understand how to use it effectively! Clear and simple advice that was easy to implement.”



“Sentinel gave us the complete solution – a perfect example of applied consultancy."



“Dynamic, applicable management training… ideally suited to our working environment.”



“As a multinational, our company can be complex and we have historically been forced to use lots of systems to cope. Sentinel helped us develop a simple system, with broad application, which has resulted in efficient, good practice now forming part of our everyday working life.”
