Working with Jan transformed the way I lead my managers. His coaching helped me shift from operational problem-solving to truly empowering my leadership layer. Through his powerful questions and practical guidance, I learned how to create clarity, set real expectations, and hold my managers accountable without losing trust.
Within weeks, the difference was visible: stronger ownership in the team, fewer escalations, and managers who finally started leading instead of waiting. Jan helped me grow into the leader my managers needed and the results followed immediately. Thanks Jan!
Managing Director IT Services – Health Care
What makes Jan exceptional is his ability to link leadership behavior to business performance.
He coached our senior leaders through a period of volatility and high growth. The improvements in clarity, ownership, and team dynamics were visible almost immediately.
EVP Operations
Jan isn’t just a coach — he’s a strategic partner. And he’s bold in his approach!
He asks the difficult questions, challenges assumptions, and helped us grow in ways that directly support the business.
Our leadership team is now more aligned, more courageous, and far more effective.
Every now and then we invite him back in to keep the saw sharp.
CEO – Professional Services Firm
Working with Jan was a turning point for our executive team. From the very first sessions, he challenged us with powerful and disarmingly honest questions — the kind that expose what you avoid, what you overlook, and what you need to act on immediately.
What sets Jan apart is his ability to translate these questions into real behavioral change. He doesn’t just coach the individual or the team; he links everything back to our operational reality. Every conversation connected directly to the way we make decisions, how we lead our people, and how we translate strategy into visible results on the floor.
Within the first three months we saw measurable improvements: higher cross-functional alignment, faster decision-making, fewer escalations, and clearer ownership across the leadership team. Our operational KPI’s — from on-time performance and quality levels to employee engagement indicators — started to shift in the right direction almost immediately.
Jan brings a rare combination of experience, sharpness, and humanity. He creates psychological safety while holding you accountable for real outcomes. His questions don’t just provoke reflection — they provoke progress.
If you want an executive coach who truly understands complex operations and who helps leadership teams turn ambition into performance, Jan is the partner you want by your side.
CEO Express Transport Company in The Netherlands
Stepping into my first executive role was both exciting and overwhelming. I quickly realized that leading at this level requires far more than expertise — it demands clarity, confidence, and an ability to navigate complex team dynamics from day one. Working with Jan made all the difference.
From the start, he asked the kinds of powerful questions that forced me to look at myself honestly: What am I avoiding? How am I showing up? What impact do I want to have in the first 90 days? These questions helped me accelerate my learning curve and step into the role with purpose instead of hesitation.
Jan guided me in translating strategy into actionable leadership behavior — how to influence peers, build trust quickly, and establish my role in an already well-formed executive team. His support was practical, direct, and grounded in his own extensive leadership experience.
Within a few months, I felt fully integrated. My confidence grew, my contribution to the team became more visible, and I started leading with greater clarity and decisiveness. Colleagues commented on my maturity and presence, and my early wins helped build momentum for the team as a whole.
Jan doesn’t coach from theory — he coaches from lived experience. His questions helped me find my voice as a leader, and his guidance helped me step into my executive role faster and stronger than I ever expected.
Director of Manufacturing Operations (Food)
Jan’s coaching reshaped the way I approach performance management across my organization. As a VP responsible for planning and engineering, I was used to solving problems myself and pushing for results. Jan helped me see that real performance comes from clarity, empowered managers, and disciplined follow-through — not from working harder or escalating more.
His sharp questions forced me to confront the gaps I had been tolerating: unclear expectations, inconsistent accountability, and managers who weren’t truly owning their part of the plan. With Jan’s guidance, I learned how to structure performance conversations, set standards that stick, and drive execution through my leadership layer rather than around it.
Within three months, we saw measurable improvements: faster cycle times, stronger adherence to planning milestones, fewer surprises in engineering outputs, and a visible shift in ownership among my managers.
Jan doesn’t soften the truth, he elevates it. His coaching helped me become a more focused, strategic, and effective performance leader.
VP Planning & Engineering, Transport Company in Germany
I had the pleasure of working with Jan as my coach and he facilitated several management team sessions. That has helped me enormously in my development as an executive, become a full confident MT member and above all this developed me as a person! Thanks to his pleasant but direct approach, Jan quickly gets to the core of your internal hurdles and help you successfully overcome them. Jan is a coach you can trust, is authentic, very (!) result-oriented (no lengthy conversations, but direct and to the point), always takes a positive approach and asks the questions nobody else asks. I found he often knows what needs to be discussed before you do yourself. I look forward to working with Jan in the future and hope to be able to reflect some of his qualities as well.
Wiljan Wander – Head of Information Security (ABMAMRO)
I trust Jan because he understands the pressure of running complex operations.
His coaching is direct, practical, and tied to measurable outcomes. He transformed how my managers lead, collaborate, and hold each other accountable. The culture shift changed our entire organization.
Thanks Jan!
European Supply Chain Director
“Jan helped us see what was blocking performance — and it wasn’t our strategy or our systems. It was leadership behavior. Within months, our leadership team was aligned, decisive, and operating as one. The business results followed naturally. Jan combines hard business insight with behavioral mastery.”
I had the privilege to work with Jan and his team rolling out a Global Management Training course. I found him to be extremely dedicated to his profession, very knowledgeable and helpful when called upon and professional at all times. His approach to start with business results and helping me identify how leadership behavior relates to this was an eye-opener for me. Clear, practical, concrete and very to the point. And it paid off!
Beyond the roll out he was always willing to assist with anything and very eager to help with information and already designed Training material to ensure one does not redo work that already exist.
His ability to deal with strategic and operational issues at the same time places him in my view in a very unique and scares category of Executive Management Team Coach. He identifies with all categories of staff in the organization and deals with you with mutual respect.
I greatly enjoyed working with Jan and hope that our career paths cross in future again.
I wish him great success in his future.
