Tell us about what you do and why?

As a holistic dentist, I educate people about the many links between oral health and general health, explaining how good health literally starts with the mouth. This encompasses nutrition, oral hygiene, sleeping, breathing, and posture. My father and uncle have both worked as holistic dentists since the 1980s, so I’ve been acutely aware of the mouth-body connection since I was a child. I’m also a fitness trainer, health coach and former professional soccer player – so I’m obsessed with performance and helping people find the healthiest version of themselves.

Why are you such a firm believer in the IQS philosophy?

I see the destruction that sugar causes on a daily basis. If the hardest part of the body (teeth) have holes in them, it’s scary to think what some people’s dietary choices are doing to the rest of their body!
