We've lived leadership from the inside.
ABOUT WELLNESSTORY
And learned that sustainable performance starts with the person doing the leading.
Wellnesstory was founded by Natasa Kazmer and Jim Callaghan after decades spent leading, building and transforming organisations in demanding environments.
We bring together lived leadership experience, behavioural science and health to help leaders perform sustainably - and organisations create the conditions that make that possible.
OUR STORY
We didn't arrive here from the sidelines.
We spent decades inside demanding organisations - building businesses, leading teams and navigating growth, transformation and change.
Along the way, we saw something leadership development often overlooks: how we lead is shaped by the human capacity we bring to the role. Our own experiences made that impossible to ignore.
Two perspectives. One idea.
