I am a clinical dental technician and have just started working in my own denture practice.

Board member: Ludwig Jansen Van Vuuren

A good relationship between the industry and the training institution is very important, this ensures that the needs of industry are heard and incorporated into the training of new graduates.  I am currently the Head of Dental Technology at the University of Otago, which provides a valuable link between the industry and the training of new graduates for the profession.

Barry Williams

Board member: Barry Williams

The futures of dental technology and clinical dental technology are exciting but not without their challenges. Our industry needs a strong and unified group of passionate people with a common belief to help insure we get the best possible outcomes to the issues that do and will continue to confront us.

My background is in Crown & Bridge and Clinical so I have an understanding of the issues as they effect both disciplines, a foot in each camp, I think the NZIDT needs to be equally representative of both groups.
