MEET DI MANTELL
Leadership when the stakes are high.
From crisis to clarity. From ICU to boardrooms.
I help leaders, boards and organisations think clearly and act decisively when certainty is thin and consequences are real.
My leadership was forged in intensive care — where decisions are made under pressure, priorities shift quickly, and calm judgement matters more than confidence theatre. That grounding shaped a career spanning executive leadership, major infrastructure, sustainable finance and board governance.
Today, I bring that perspective to boardrooms, conference stages and advisory roles, translating crisis management into critical thinking for complex environments.
What I do
Speak — practical, engaging keynotes for leaders navigating complexity and change
Advise & Govern — board and advisory roles focused on judgement, risk and long-term value
Mentor — supporting leaders to step into their authority with clarity and confidence
Why organisations work with me
Because I’ve led where decisions had weight — and consequences lasted.
Let’s talk
If you’re shaping leadership conversations, strengthening governance, or navigating what comes next, I welcome the conversation.
