Working Together
I work personally with founders, CEOs, Chairs and boards who are facing high-stakes decisions and do not have a safe place to think them through.
This is not coaching or consultancy.
It is a short, confidential decision engagement for moments when the consequences are real, the window is closing, and internal advice feels unsafe, political, or insufficient.
My background spans decades of senior leadership and decision-making in safety-critical and commercially critical environments, where judgement under pressure was not theoretical.
I work selectively and by fit.
I believe that relationships are built on mutual trust, respect, empathy and ethics.
Availability is limited.
Fees are fixed and agreed and paid in advance.
Please note that I do not offer keynotes or public speaking.
