Helping leaders
to tackle
real leadership challenges.

For over 20 years, I’ve been fully immersed in the professional world — from large corporations to thriving SMEs and fast-growing scale-ups.

Over the past years I’ve helped +100 leaders to tackle real leadership challenges. My approach is honest and down-to-earth. I go beyond theories and work with you to get practical results. I do this in Dutch, French, and English alike.

Depending on the challenge, I tap into a trusted network of freelance advisors, fellow SWTRs, who share my no-nonsense approach to deliver the results your organization needs.

Built to stretch.

SWTR moves leaders, like a sweater that moves with you. It’s about embracing the stretch – expanding your perspective, building resilience, and unlocking growth that sticks.

Reliable.

SWTR feels like a trusted sweater – a trusted companion in leadership, where leaders feel safe, open up and achieve real progress.

Practical.

As adaptable as your favorite sweater, SWTR delivers practical advice tailored to your needs. No rigid theories, just straightforward advisory that helps you cut through the noise and focus on what truly matters.

Ready to lead
with courage?

Let's talk.
