Our Team

Castaliagroup Andrew Meek
Andrew Meek
A conversation with our CEO

At Castalia Group, we believe that leadership is about more than just business – it’s about people, community, and making decisions that last. For Andrew Meek, our CEO, these values have shaped his career and continue to guide the way he leads our organisation.

Growing up in the German Alps, Andrew’s upbringing in a tight-knit village taught him the importance of resilience, collaboration, and sustainability. “Growing up in the Alps, I learned that success isn’t just about individual achievement – it’s about working together for the greater good,” says Andrew. This lesson has stayed with him throughout his journey, influencing the way he leads at Castalia.

As CEO, Andrew believes that business decisions should be driven by long-term impact, not short-term gains. “We’re building something that lasts,” he explains. “It’s about creating an environment where people can thrive, where we make decisions that benefit both our team and future generations.”

Andrew’s approach to leadership is rooted in adventure – not in the traditional sense, but in pushing boundaries, taking calculated risks, and embracing new opportunities. “Adventure, for me, means stepping outside the norm and challenging the status quo,” says Andrew. “It’s about having the courage to take risks, knowing they’re aligned with our values and will lead to long-term success.”

Outside of work, Andrew’s love for the outdoors remains a key part of who he is. He believes that nature provides a humbling perspective on life and leadership. “Spending time in nature helps me stay grounded and reminds me that the decisions we make today have an impact for generations to come.”

Through his leadership at Castalia Group, Andrew continues to build a legacy of resilience, compassion, and sustainable business practices, ensuring that our organisation remains values-driven for years to come.

Aaron Hewitt
A conversation with our CFO

Over the years, Aaron has focused on developing relationships, strategies and structures that help businesses thrive and stay sustainable, making a positive impact on both shareholders and clients.

“I’ve been lucky to work with some incredible people who have really shaped how I think about business and leadership.

Lifelong learning is something I’m passionate about, and I always see every experience as a chance to grow and refine my perspective. This mindset keeps me optimistic and reinforces my belief that challenges are just opportunities waiting to be unlocked.

Family is at the heart of everything I do. My wife Chelsey, our kids Lottie and Jake, and I work together to build a life filled with strong values, creativity, and purpose.

Looking back, I’ve realised that true success isn’t just about what you achieve; it’s about the relationships you build and the positive impact you have on others. I’m proud to be part of a team that shares these values, strives for excellence, and is committed to making a real difference.”
