Strategic Where it Matters, Hands On Where it Counts

20+ years of SES-level leadership across government, regulatory, and transformation portfolios.

Julie Is The Calm In The Storm

For over two decades, I’ve been the executive leader organisations call on when stakes are high, environments are complex, and transformation isn’t optional.

I stabilise underperforming teams, rebuild trust where it’s been lost, and lead with a clear-eyed understanding of what it takes to deliver lasting change — operationally, culturally, and strategically.

From public sector bodies and regulatory commissions to private enterprise and critical infrastructure, I’ve guided executives, boards, and project teams through moments of uncertainty and opportunity alike. But I’m not here to list roles — I’m here to tell you this:

I bring both the head and the heart of leadership.
Sharp thinking. Commercial acumen. Unshakable integrity.
And a proven ability to see the system, fix what’s broken, and deliver outcomes that matter.

MY FIVE GUIDING PRINCIPLES

Integrity Without Ego

I act in service of outcomes, not accolades. Quiet strength, not performance.

Calm In Complexity

When pressure rises, I bring order, perspective, and clarity. The storm never leads the leader.

Systems Thinking

I see beyond the symptom. I map the root cause, the ripple effect, and the solution that lasts.

People-First Execution

I deliver results with people, not at them. Performance is built on trust and inclusion.

No Fluff, Just Follow-Through

I don’t overpromise - I deliver. Clean plans, clear ownership, and visible outcomes.

WHAT I BRING TO THE TABLE

Practical expertise. Proven delivery. Full-service leadership - tailored to your environment.

Executive Stabilisation

Leadership to restore calm, structure, and trust during transition or turbulence.

The most powerful transformation doesn’t start with a project plan. It starts with purpose.
