Culture Δelta
An independent voice for boards and executives seeking organisational culture change.
Led by Dr Sarah Ogilvie — AHPRA-registered psychologist with 20 years' experience across corporate, government and NFP organisations. Providing evidence-based culture reviews and psychosocial risk assessments and guidance on implementing practical change recommendations grounded in behavioural science.
Culture isn't a soft issue. It's a governance issue.
Dr Sarah Ogilvie works at the intersection of psychology, governance and risk. As the founder of Culture Delta, she brings boards and executives the independent perspective they need when culture, conduct or psychosocial risk has become a problem worth solving properly.
Sarah developed EY's behavioural and cultural auditing approach (BEAM) and led its Oceania practice for over a decade. She is an Honorary Senior Fellow at the University of Melbourne's School of Psychological Sciences, and has advised regulators, boards and executive teams across financial services, government, health, defence and superannuation.
Her work has shaped integrity frameworks for Victorian government departments, supported post-incident reviews in health, and informed risk culture practices across major Australian banks.

When the stakes are high, you need someone with no horse in the race
Internal reviews struggle to surface what people are really experiencing.
An independent reviewer holds confidentiality differently — and people speak more honestly.
Big-firm consultancies have commercial relationships across the organisation.
Independent practice means no cross-sell, no protected relationships, no compromised findings.
Generic frameworks miss the specific behavioural drivers in your organisation.
Behavioural science methodology pinpoints where culture is enabling — or quietly eroding — what you're trying to do.
Reports often stop at diagnosis, leaving leaders to figure out the 'so what'.
Findings are translated into co-developed action plans owned by the people who'll live them.
"Independence isn't a posture. It's a structural condition that lets boards trust what's in front of them."
Independent reviews, board-grade reporting, lasting change
Each engagement is bespoke — scoped against the question your board or executive team needs answered.
How an engagement unfolds
Listen & Understand
Confidential conversations with leaders to frame the question that really matters.
Design the Review
Tailored, mixed-methods approach — interviews, focus groups, survey, document review.
Go Deep
Independent fieldwork that gets beneath the surface, with psychological safety throughout.
Deliver the Truth

Chart the Path Forward
Co-developed action plans with the people who will own and live the change.
What boards and executives say
Sarah brought the rigour of a regulator with the warmth of a trusted advisor. Our board finally saw what we'd been talking around for years.
Independent, fearless, and grounded in evidence. Exactly what we needed after a difficult year.
She doesn't just diagnose — she helps you carry the change. Our leadership team are still using her frameworks today.
Start with a conversation
No obligation — just a discussion about what you're seeing and how I might be able to help.
