Thirty years in human development, organisational design, and transformational change. Fourteen years in executive coaching. M&A integration specialism built through direct practice — on both sides of the acquisition table.

Founder
Quartey Group
In my own words

I have spent thirty years watching organisations either come together or quietly come apart.

The patterns are not subtle, once you know what to look for. They are visible in the first meeting, in the language people use when the founder is in the room, in the questions the new CEO does — and does not — ask.

Quartey Group exists because the human work of integration is treated as secondary to the financial and operational work. It is not. It is the work that determines whether everything else holds.

Background

Nearly thirty years building a single lens.

She started in HR — not as a stepping stone, but because she was genuinely fascinated by why people behave the way they do inside organisations. Why capable people become disengaged. Why talented teams fracture under pressure. Why systems designed by intelligent people so consistently fail the humans inside them.

That question took her through two decades of work: from HR into organisational development, into large-scale transformational change programmes spanning multiple industries. She trained as a coach, then as a therapist, accumulating expertise in occupational and organisational psychology, neuroscience, and positive psychology. Not to assemble a credentials list. Because each discipline gave her a sharper answer to the same question.

Then, at different points in her career, she found herself on both sides of an acquisition. Once as the acquired — relocated into a different culture, watching silos form and the most capable people quietly begin to look elsewhere. Once as the acquirer — close enough to see how little thought had been given to what the combined organisation would actually feel like to live in. Both times, the same pattern. By the time anyone acknowledged the culture problem, the plane was already losing altitude.

The Pivot

You cannot build leadership alignment six months after two teams have calcified into opposing camps.

Later, working as a consultant, she was brought in to fix integrations that had already broken down. The damage was done. You cannot reconstruct trust that was never designed in the first place. That became the foundation of a different kind of practice — one that begins at the close, not at the crisis.

The N.E.W. CO.™ Framework is the methodology built from everything she has seen, lived, and studied. It begins where every other integration framework ends: with the people. The 4-intelligence model at its core — IQ, EQ, PQ, HQ — is the lens through which every leadership situation is read: not as a personality assessment, but as a map of where the risks lie and what the integration will cost if they are not addressed.

Research validation

Two independent academic research teams, commissioned separately to investigate leadership challenges in M&A integration, arrived at the same conclusion — and the same conclusion she had reached through thirty years of practice.

“People-centred integration is essential to the success of mergers — it is not an option.”

The first meeting sets everything. Most CEOs don't know it yet.

The org chart shows you the structure. It tells you nothing about the power.

Every acquisition creates a New Co. Almost no one leads it that way.

Most new CEOs prepare their first town hall. Very few prepare for it.
