You have made things happen in a subtle yet effective manner. It is without doubt a testimony to your expertise, knowledge and deep understanding of the UN. I am therefore not surprised to learn that you contributed so much to our work over so many years. It would be also my pleasure and to stay in touch with you and collaborate in common endeavour to making the world a better place for human kind. A tough call in these rather troubled days. With sincere appreciation.

Parfait Onanga-Anyang, Head of MINUSCA Nigeria, April 2015

The training was very relevant and appropriate to my day to day running of the organisation. Excellent facilitation by well experiences facilitators/resource experts, with ready practical examples and ways to keep the training alive. I am taking away with me a specific commitment to go and develop myself better as a leader, making sure that I improve on my attitude towards colleagues and using positive language to build them into a good team. With the right positive attitude and language used in interacting with others, our organisation will become more of a team and therefore perform better.
