About Dawn Consulting Services
Transforming People & Culture for Lasting Impact
After 29 years leading teams for an international hotel company across Asia, the Pacific, Europe, and the Middle East, Christine Rumble returned home to Perth, Western Australia, at the end of 2020. Eager to channel her passion for developing people and building inclusive, high‑performing cultures, she founded Dawn Consulting Services — a partner for leaders who want to create workplaces where everyone feels valued and empowered.
Christine works with organisations to drive meaningful change through leadership coaching, culture transformation, and robust HR strategies that consider every stage of the employee journey. Recognising that no single consultant can meet every need, she also collaborates with a network of trusted specialists whose complementary expertise ensures clients receive holistic, tailored support.
Why “Dawn”?
In an era of constant change, agility and transformation are essential. Dawn symbolises the start of a new day — and a fresh beginning for leaders and organisations ready to evolve. (And yes, it’s also Christine’s middle name.)
Our Values…
Trust & Respect
Building relationships grounded in integrity
Empathy
Understanding people to unlock their potential
Empowerment
Equipping leaders and teams to thrive
About the Founder
Christine Dawn Rumble is an accomplished international executive with extensive experience leading diverse teams across multiple countries and cultures. Her career began in hospitality operations, progressing from Activities Manager to Hotel General Manager with Accor Hotels in Australia and New Zealand.
Her passion for developing talent led her into learning, development, and HR leadership roles, culminating in senior positions such as VP Learning & Talent Development – Asia Pacific and Chief Talent & Culture Officer – Accor Asia Pacific, where she oversaw HR strategy for 1,200 hotels in 23 countries and more than 140,000 employees.
Today, she co‑owns Denmark Chocolate Company and Wine Tree Estate Chalets, two thriving tourism businesses on the southern coast of Western Australia. Drawing on her leadership, branding, and operational expertise, Christine successfully repositioned both ventures to deliver exceptional guest experiences and sustainable growth. With these businesses now operating at optimum levels, she has returned her focus to consulting — bringing fresh, real‑world insights to the leaders and organisations she supports.
A lover of great conversation, fresh food, and fine wine, Christine is delighted to be back in her home country but looks forward to global travel again in the not‑so‑distant future.
