I embarked upon post graduate studies with the Queensland university in Australia at the early stage of pursuing this vocation, and my resolve in this facet of medicine was reinforced by the fact that I’ve been able to readily provide a quick access to care for many patients that has saved the lives of many – its such a wonderful feeling to save someone’s life!”

Dave Rouse

Audit & Medical Compliance Director

Chartered Member of the NZ Institute of Directors, ISO Lead Auditor, Qualified Engineer, and Systems & Processes Business Coach, Audit & Medical Compliance Director for NZ Plastic Surgeons Ltd.

“As a former Med student, I’m loving being surrounded by great medical professionals once again.

Following the loss of my Grandfather recently to Melanoma (which was misdiagnosed by his GP to begin with), I wondered why more Kiwi’s don’t go to skin cancer specialists for checks. After all, we have the highest rates of Melanoma in the world courtesy of the hole in our protective Ozone layer!. I have a passion for lowering the barriers to getting skin checked by skin cancer specialists in an effort to catch cancers while they are benign / treatable. One of those barriers was being able to quickly deal to skin cancers upon discovery, so that patients don’t need to be scared about what might be found and the subsequent bounce around the medical fraternity to get treatment. Which is why we structure our business to enable access to treatment and peace of mind very quickly, efficiently, and seamlessly with the same crew looking after you the whole way.

I am seeking to identify and recruit (or join forces with), the best in the industry in NZ so that we can remove those barriers and help more people get the checks that should be a part of our life here under the NZ sun. Hopefully in the years to come, far fewer people had to suffer the way my Grandfather and our family have.”
