Brain-Based,Heart-Led

We are wired for connection. And genuine connection begins within—with our own neurobiology.

For over 25 years I’ve integrated nutrition research, executive coaching, supervision and applied neuroscience to help professionals and leaders navigate tension, stress and overwhelm— with greater clarity, focus and purpose.

I call this approach Brain-Based, Heart Led— or in Dutch: Voor Hoofdzaken die het Hart Raken.

What I bring:

25+ years integrating coaching, supervision, and applied neuroscience
Co-author of Supervision for Coaches — a handbook for professional coaches and supervisors (Dutch, 2025; English, 2026)
Independent research and articles on the embodied dynamics in leadership, coaching and supervision
Structured facilitation style and comfortable facilitating in Dutch and English

Curious whether this fits what you’re navigating? Let’s talk.

A new 2026 program — Brain-Smart, Practice-Wise — starts in September 2026: events-calendar here below:
