Step 1

Our governance team is a mix of passionate, longstanding staff members and independent advisory experts that understand our vision and drive us to deliver on it.
As a 100% employee owned company, our directors are also managers and shareholders of the company. To ensure we are bringing fresh ideas and insights to the table, we have two independent advisors that help us define and implement our strategy and vision.
