Work With Di

I work with organisations in three ways. Each is grounded in experience, not theory.

Speaking & Keynotes

For conferences, leadership forums and executive teams.

I deliver engaging, grounded sessions that connect lived experience with practical insight — helping leaders navigate complexity, pressure and change with greater clarity.

Typical topics include:

Leadership when certainty doesn’t exist
From crisis management to critical thinking
Decision-making under pressure
Sustainability as a governance discipline
Career longevity, reinvention and transition

Board & Advisory

For boards, chairs and organisations navigating complexity.

I bring executive-level experience, strong governance capability and sound judgement to board and advisory roles, particularly in environments involving risk, transition, sustainability and multiple stakeholders.

I am valued for:

clarity in ambiguous situations
a people-centred but commercially grounded lens
translating strategy into decisions that hold over time

Mentoring & Facilitation

For leaders at pivotal moments.

I mentor and facilitate with a focus on confidence, judgement and leadership presence — supporting people to step into the room they’ve already earned.

Testimonials

What a legend .. I love Di’s no-nonsense approach to work and life.

Saying yes to opportunities and being adaptable were the key take-outs for me.

Also drawing on the “let them” approach is a good reminder. 🙂

- Carol Sheahan

So many great lessons in Di’s words of wisdom. In addition to the 45 second rule, here were a few other favorite take aways:

• Dealing with Imposter syndrome – address fear through action
• Improve by 2% each week – work towards your goal
• Believe in you – confidence will get you so far, but need to believe in yourself first ie: remove self-doubt

- Tiffany Sutton

It was inspirational listening to Di talk about her journey & is definitely someone to look up to.

I loved her authenticity and vulnerability opening up about her life and challenges she has faced in her path through leadership.

I’ve had the pleasure of working both alongside and with Di since the opening of the new Royal Adelaide Hospital.

Di is collaborative, open and honest- she displays thoughtful and effective leadership of both her teams but just as importantly, those adjacent, outwards and upwards.

No ego, no games, just focused on positive outcomes for patients, the community and the environment.
