Health guidance with heart and an open mind.


I will listen to you and try my best to appreciate your health journey and help get you where you want to be. A good therapeutic relationship involves sharing hopes and fears, being realistic and defining and managing expectations.

Generally speaking there are no magic pills and quick fixes. What effects real change is mindset, lifestyle and diet modification, judicious use of supplements and medication, and being kind to yourself. Take ownership and understand YOUR health, your body and the pressures you are subjected to.

I practice all aspects of medicine, with an interest in bio-hacking and individualised inflammation  modulation. Specifically in: 1) pregnancy and early childhood optimisation, 2) atopy: asthma/ hay fever/ eczema, 3) microbiome, 4) cancer 5) neurodegenerative diseases and 6) complex chronic conditions like CFS. I approach health from a realistic, whole-body perspective where the patient is a partner in their journey, with as much help and guidance from me as you are comfortable with. My assessments are rigorous, research-dense and fully referenced.

I always accept communication from other doctors and health professionals and welcome a chance to help with your complex case. There is no fee for this as collegiate networking and information-sharing is very important to me.
