'For a period of just over two years, I worked closely with Willem in my role as CEO of a high-end optical and audio retail organization. I found Willem's knowledge and experience invaluable as we discussed cases together, with him providing clear and insightful feedback, and demonstrating a strong analytical ability to elucidate processes or behaviors of individuals. Willem's extensive experience and background make him an excellent coach and sparring partner, providing valuable support. I also found his broader coaching role with my management team to be professional, functional, and enjoyable.'

 ‘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.’
CEO, international retail company, the Netherlands

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.

Professor of Organizational Behaviour, IMD Institute for Management Development

'I worked with Willem more than 5 years with my management teams in Malaysia, Nigeria and China. He has been instrumental in working closely with me to diagnose a variety of situations and develop and implement programs to help improve organisation performance.

Willem has never been really a 'corporate guy'. He always stays in touch with and implements new approaches and techniques in helping get the best out of people.

This said, he is well versed with the corporate world, and is therefore able to well understand and contribute to content (business strategy and operational issues), which makes his interventions meaningful, valuable and relevant.

Finally, Willem is jovial and customer focused, yet is not afraid to speak his mind.
His style is open and reflects a balance of planning and spontaneity.
He is culturally sensitive and has global exposure, making him a truly valuable business partner to any senior leader looking to make a big impact with people.' 

CEO, International FMCG Company

‘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 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.

Managing Director, Dairy Ingredients Company

'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.' 
Managing Director, International B2B company

'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!'
