Testimonials
Zaklina Craig, Executive Director, Business NSW
In this interview, Zaklina Craig reflects on her 15-year journey using the Human Synergistics toolset to drive cultural and leadership transformation in organisations. She highlights the profound impact tools like LSI, OCI, OI, and leadership/management impact assessments have had in fostering self-awareness, promoting behavioural change, and catalysing performance improvement.
Zaklina emphasises the importance of good character in leadership, especially in unseen moments, and the power of these tools to spark meaningful conversations about culture and behaviour.
Siabhan McGlinchey
In this interview, Siabhan McGlinchey shares her deep insights on the importance of intentionally developing culture and leadership within organisations. With over 15 years of experience using Human Synergistics tools, she emphasises that culture is everywhere—it can be positive or negative—and that meaningful change happens one leader at a time. Drawing on her leadership experiences at brands like Pizza Hut, KFC, and Taco Bell, Siabhan highlights how great cultures are built through consistency, clarity, and systemic approaches.
She cautions against scattergun efforts in culture work and instead advises organisations to develop a clear, strategic plan rooted in self-awareness and leadership development.
Grant Kerswell, CPO, Ingham's Group Limited
In this interview, Grant Kerswell reflects on Inghams’ cultural and leadership transformation journey, emphasising the importance of evolving leadership to revitalise an organisation with over 100 years of history. He explains that deeply ingrained behaviours were holding the business back from achieving its full potential, prompting the need for a more constructive and inclusive culture.
Grant offers practical advice for organisations embarking on a similar journey: secure strong sponsorship from the CEO and board, invest in internal accreditation for key HR staff, and gain clarity with your leadership team on your purpose, ambition, values, and desired behaviors. He stresses that culture change requires alignment, leadership, and patience—it’s not a linear process, but one that can drive sustainable improvement.
Matthew Tripolone, Managing Director, IHG.

Angela Ewers, Chief People Officer, ARN Media
Angela Ewers shares a deeply personal and practical reflection on her journey driving leadership and culture change at ARN. The decision to focus on these areas stemmed from a clear need to shift the organisation to meet both internal challenges and evolving external demands. The business strategy required transformation—and with that came the realisation that developing the right leaders, demonstrating the right behaviours, was the key to unlocking meaningful progress.
Angela emphasises the importance of helping leaders grow their capability and confidence—to “let go,” coach instead of control, and inspire teams to do their best work. By helping people shift their thinking styles and understand how those styles influence behaviour and results, the organisation saw clear improvements in engagement, innovation, teamwork, and pride.
Rachel Glasbergen, Senior Business Leader at Sanitarium
Rachel Glasberger shares a powerful and inspiring story of how a constructive culture has been the cornerstone of success at Sanitarium—especially in the launch and growth of its new business unit, The Alternative Dairy Co. In just four years, this innovative brand, developed in response to a growing consumer trend for plant-based milks in specialty coffee, has grown to over $80 million in value. According to Rachel, culture was not just a contributor—it was a key enabler of that success.
Rachel’s leadership approach blends ambition with humility, structure with empowerment. She believes in setting a clear direction but also creating the environment for others to shine. As a result, the business hasn’t just achieved financial success—it’s unlocked people’s passion, built new capabilities, and strengthened partnerships both internally and externally.
