Effective teamwork begins with the right conversation.

James is an exceptional professional and a remarkable human being. During our agile transformation, he brought a refreshingly clear vision to our culture and team dynamics. His 'superpower' is building a feedback culture that actually works—he doesn't just preach it; he lives it. He combines deep expertise and warmth with a sharp vision for the future. An absolute recommendation.

Mike Bouckaert, Director and founder

The Feedback Journey showed me that feedback only becomes truly valuable, and easier, when it contributes to connection and collective growth. A training program that has brought me so much, both professionally and personally.

Sarah Roodenburg, Agile Team Coach

Unlike many other training programs that only focus on feedback techniques, this training targets the essence. James reframes feedback as the start of a dialogue. By making it a priority to check how feedback is received and staying genuinely curious about the other person, he transforms interactions into connecting conversations.

Thanks to this journey with James, everyone on the team now feels brave enough to speak up. We’ve become a closer, more productive, and more autonomous team. The trainer’s insightful questions helped us get straight to the heart of the matter and set clear goals.

Julia Willemse, Team Lead Recruitment

This feedback training didn’t just give me professional tools—it gave me the confidence to handle challenging conversations in my private life through genuine connection. James consistently held up a mirror for me, helping to uncover the pain points in my communication style. I highly recommend it, even if you think you already know everything there is to know about feedback.

Wendy van Epen, Lead Developer

James combines strategic sharpness with genuine empathy. He helps teams and organizations grow in ownership, collaboration, and culture. A person of integrity and trust—someone of immense value.

Freek Gerritsen, Product Owner

The feedback training has helped me improve my communication. I’ve noticed that I connect with colleagues more easily, collaboration flows more smoothly, and I can apply my technical expertise with greater impact. As a result, I can now coach others in their growth more effectively.

Bas des Bouvrie, Team Lead

I got to know James during my time at Coolblue, where I followed several trainings with him, including Nonviolent Communication. He created a safe and open atmosphere and used concrete examples that made the learning very practical. The training still helps me in my daily work and life, and the way he facilitated it has really stayed with me.

Pieter Lijzen, Scrum Master

James was an amazing coach during our time at Coolblue. I grew a lot through his guidance and was especially impressed by how he balanced directness with genuine care. He shows how powerful feedback can be when done well and helped teams grow into self-managed, high-performing units. Working with him was a real pleasure, and he is a valuable asset to any team or organization.
