Brain-Based,Heart-Led
We are wired for connection.
And genuine connection begins within—with our own neurobiology.
For over 25 years I’ve been integrating executive coaching, training and supervision with insights and research in the sciences of applied neuroscience, positive psychology, physiology, nutrition and behavioral change.
In a world of ever-increasing demands – and biologically limited energy – I help leaders and professionals navigate tension, stress, and overwhelm with greater effectiveness. I support clients in regulating the biology of their brain and body, so they can think clearly, focus, and act with purpose..
My approach is practical and lasting: Brain-Based-Heart Led (In Dutch: Voor Hoofdzaken die het Hart Raken).
Clients value my capacity how I bridge strategic thinking with neuroscience grounded insights and practical learning.
I co-authored Supervision for Coaches a handbook in Dutch for coaches, supervisors and their professional associations. English edition arrives May 2026.
