‘I have been working with Willem for more than 4 years. Willem is a personal coach to me and he facilitates our team’s performance during special MT sessions. Willem has been pivotal in the successful change journey of our Food & Beverages MT. He combines excellent analyzing and listening skills. In our sessions he captured quickly the essence of our team dynamics and let us experience real improvements with simple practical exercises. He used models and frameworks enriched by his own experience, really appropriate for the situation. He managed in a few sessions to make us a real team instead of being representatives of our disciplines. Also, with Willem’s help we made a step-up in working together and making our meetings are much more efficient by focusing on crucial matters.

 ‘Willem was involved in resolving a big complex departmental crisis which had been going on for much too long, so long that it had become part of the working culture. He showed himself as an expert whom people tend to take as an authority. And was able to unwind all stories and get the problem on the table.’

I very much enjoy and appreciate using Willem as a coach on my programs. Willem brings with him a rare combination of extensive business experience and deep psychological knowledge. This gives him immediate credibility and legitimacy with the senior executives that attend my programs. This, combined with his ability to truly meet the participants where they are and his positive mindset, inevitably contributes to these executives leaving with new insights in themselves and concrete plans to improve their impact.

'It took Willem only 24 hours to create a top team out of our team. Two months in the role of as managing director, I asked Willem his help. My management team was not yet a top performing team even though all the individuals were top performers themselves.

Willem has developed over the years a deep knowledge on how to unleash top team performance. He has broad experience of tools and techniques that are very effective although sometimes out of your comfort zone. Especially the latter effect helped us as a team to get to know each other better and really bond. We still use the lessons learned on those days to boost our team performance every day. It is not only the knowledge and techniques that make Willem effective but he also radiates trust and is easy to bond with. People feel safe around him which is crucial to make true connections with each other. If you need to boost your or your teams’ performance, Willem is the go-to person.'

'I had the opportunity to work quite closely with Willem for a couple of years and it was a very valuable experience. Every single time I spoke with him it has been worth for me. Don't expect Willem to come with a pre-packaged solution for you. He always helps you to find solutions, often hidden in the back of your mind. He helps you in understanding how you can deal with challenging situations, often by challenging yourself. He helps you in understanding others and see different points of view. He helps individuals in becoming better individuals and teams in becoming better teams, what else? Yes something else... he does it with a big smile... which always helps!'

Daniele Voltini, Entrepreneur, former CEO Avanzi, Italy

' I see Willem as a man driven by conviction, understanding and optimism:

- A conviction to lead individuals and organisations to the next level by pointing or nudging towards the next mountain to climb

- Understanding of the corporate constraints, business needs and power struggles inherent in life in organisations and yet

- Optimistic about people’s ability to free themselves from unnecessary habits and assumptions and able to create a learning atmosphere where people are happy to experiment with new ways.

You will find in Willem and credible partner, a skilled facilitator and a delightful colleague.'
