Clinical Advisory Board

At Lumino The Dentists, we believe in building partnerships with our clinicians who play a critical role in the success of the Lumino dental business, and lead the way in providing quality and clinical excellence.

The Clinical Advisory Board provides a voice for our clinicians, enabling them to express their opinions and provide valuable input into the vision and strategy of our business. The Board is led by senior clinicians from within the group, who work in partnership with management to ensure the ongoing success of the Lumino business.

Lumino The Dentists is leading the way in dentistry in New Zealand, and there are significant opportunities for clinicians as we continue to grow the network.
