Meet our Senior Leadership Team who are accountable for delivering the mission of Eye Institute

Dr. Nick Mantell

Managing Director, co-CEO and Cataract, Refractive Eye Surgeon

A specialist in cataract and refractive laser surgery, Dr Mantell has restored the vision of many thousands of patients during his 20-year career in private practice. He feels that we are privileged to be trusted by our patients to restore their vision. This is a responsibility we all take very seriously.

Dr Mantell loves spending time with his wife Michelle and their dogs, who are truly the masters of the home. Any spare time is for the outdoors – water-skiing, running, and skiing. People would be surprised to know that their surgeon was a former front-rower for Auckland and Waikato Provincial Rugby. His ultimate moment was winning the Ranfurly Shield with Waikato!

John Fischer

co-CEO

Prior to joining Eye Institute, John was the Chief transformation officer at listed telecom Vital, where he was involved in restructuring the business. Before Vital, John spent 25 years trading global markets in NZ, Australia, the UK and Singapore.
