Unlocking workplace potential
Helping leaders create thriving organisations for the future
Leadership Development | Executive Coaching | Conflict Resolution | Culture Change
Welcome
Hello. I’m Lisa de Jong — a values-led People, Culture and Change Consultant with global experience leading organisational transformation and behaviour change.
Throughout my 25-year career, I have worked as a trusted advisor to senior leaders and organisations, helping them turn people and organisational priorities into practical action and meaningful impact.
I set up Purple Stone in 2015 to partner with ambitious organisations, supporting them to unlock potential, elevate performance and sustain change.
Today I work independently on fractional, interim or freelance consulting assignments. For larger projects, I can draw on a collective of experienced specialists with complementary expertise across culture, leadership and organisational change. I also work as an Associate with other consultancies.
Every day, I feel privileged to be entrusted by senior leaders to help them take their leadership and organisations to the next level.
I look forward to welcoming you to the Purple Stone community soon.
Let’s work together …
-

Leadership Development
Inspirational leadership unlocks innovation, customer satisfaction and profitability.
People perform at their best when they feel excited about the future, empowered to contribute and challenged to stretch. When they feel happy, valued and psychologically safe.
Leadership teams typically partner with me to build energy, uplift performance, embed new ways of working, or address conflict.
They say they appreciate my ability to engage teams, get to the heart of the issues that matter, and encourage action that delivers meaningful change.
-

Executive Coaching
When leaders lead well, team and organisational performance follow.
The best leaders are purposeful, reflective, agile and brave. They pay attention to how and why they show up as they do, and make regular adjustments to achieve even better outcomes.
A globally experienced NLP coach, I help senior leaders explore the mindset, behaviours and habits needed to take their leadership performance to the next level.
Leaders tell me that they value my people-first approach and the candid support and challenge I bring to each session.

Conflict Resolution
Strong, healthy work relationships boost well-being and productivity.
If things go wrong, strong emotions can easily escalate into lasting conflict. That’s when people need calm, confidential and non-judgmental support to find a way forward.
An ADR Group qualified workplace mediator, I work as an impartial conflict resolution specialist supporting individuals and teams going through tricky times.
People say they value my skill in surfacing difficult issues, facilitating constructive conversations and identifying “good-enough” solutions that move everyone forward.
-

Culture Change
Thriving organisations take active responsibility for culture shaping.
When ambitious organisations want to deliver on bold strategic plans they define and activate the culture they need to get there as quickly and effectively as possible.
Our small team of global culture experts partner with executive and business teams to assess current culture strengths and define critical adjustments needed for future success.
We also design and deliver holistic culture programmes to accelerate and embed transformational change across geographic boundaries.

Liz Stanley
Change & Culture Specialist
I’m an Organisational Change consultant with over 25 years’ experience of helping leaders, teams and organisations create the behavioural and cultural changes needed to boost performance and fulfil their potential.
I'm fascinated by what drives our behaviour at work and how we can reframe our thinking to create more productive, inclusive and rewarding cultures that enable people and businesses to thrive.
I have combined consulting work with studying for a PhD in Organisational Psychology and I therefore bring a blend of intellectual curiosity, academic rigour and practicality to my work. I am interested in ideas and theory, but also in the evidence of what works in practice.
I consult and coach at individual, team and organisational levels and have experience of working in many countries across a range of sectors in both large and small organisations.
