Most of what I care about in medicine comes back to prevention. I've worked right across general practice, and I've spent extra years studying nutritional and environmental medicine, because so much of lasting health is built quietly, long before anything goes wrong.

That said, I know illness rarely waits for the right moment. When something urgent lands, I want to be the person who steadies it and helps you find your footing again.

I'm based in Sydney, and when I'm not in clinic or online I'm usually on a mountain trail somewhere with my kids and our two dogs. It keeps me grounded, and honest about how ordinary life and health fit together.

If something's on your mind, let's look at it together.
