Brain-Based, Heart-Led

Clarity is not just a mental leadership skill. It’s a physical state.

We are wired for connection, and genuine connection begins from within, with our own neurobiology.

For over 25 years I’ve combined nutrition research, executive coaching, supervision and applied neuroscience to help professionals and leaders meet tension, stress and overwhelm, and move through them with greater clarity, focus and purpose.

Brain-Based, Heart Led, or in Dutch: Voor Hoofdzaken die het Hart Raken.

What I bring:

Registered nutritionist-researcher, coach supervisor (LVSC) and Master Neuroplastician
Co-author of Supervision for Coaches, a quality assurance for coaching a handbook for professional coaches and supervisors (Dutch 2025; English 2026)
Independent research and articles on the embodied dynamics of leadership, coaching and supervision
Structured warm facilitation, in Dutch and English.

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