What was really going on
The website was only part of the problem. Disconnected systems, fragmented content and an expensive external retainer were slowing everything down.

What was really going on
They didn’t need posts. They needed a strategy, and the team they already had needed developing rather than replacing.

About Sonja
I’ve spent more than two decades building businesses, leading teams and helping organisations navigate growth and change.
I’ve founded and exited businesses, built a certified B Corp, and held senior executive roles in national healthcare, including Chief Marketing Officer and Chief of Growth. I’m also a board director, GAICD graduate and hold a Master’s degree in Economic Geography.
Today, through Ceri & Co, I work with founders, leadership teams and purpose-driven organisations who need more than advice. They need someone who can see the bigger picture, challenge assumptions and help turn decisions into action.
I bring the perspective of someone who’s been accountable for the results, not just the recommendations.
