Reinvention is the path to sustainable performance - at work and in life.
My Philosophy
I believe people do their best when they’re clear, confident, and supported to grow. So I coach with straight talk,
practical tools, and real accountability. My personal work is helping individuals rebuild after major life changes. I will help you rediscover purpose and direction,
set big goals, and optimise your day to achieve success.
For organisations, your competitive advantage is creating engaged, trusting and high performing teams, and strong
leadership and cultures where people are connected to purpose and to each other. These behaviours drive engagement
and performace.
Through ReinventionLab and my connected programs, I bring together leadership, culture, career and wellbeing to create lasting change - built for the long game.
More about me
I believe in the dignity and privilege of work - the opportunity it gives us to create, contribute, and find purpose. I mentor and coach individuals who are navigating major life changes or loss, helping them rebuild their careers and lives with confidence.
As a career builder, I guide people to:
- Discover their unique value
- Define their purpose
- Rebuild with clarity and strength after transition
- Grow into authentic, resilient leaders
Beyond career development, my passion is advancing Healthspan - the number of years we live in good health, free from chronic disease and major illness. My goal is to help people not only live longer, but live and lead better.
With over two decades of experience partnering with leading organisations such as Westpac, Deloitte, World Vision,
Telstra, RACQ, government sectors and not-for-profit organisations, I lead individuals and teams through transformative change
and growth. As Head of People and Culture, I focus on creating a human first environment where people and performance thrive -
shaping culture, driving engagement, and aligning talent with purpose and strategy.
