'Let food be thy medicine, and medicine be thy food'

Hippocrates, founder of modern medicine


Hi and welcome!

My name is Dr Marissa Kelaher, I am a qualified medical doctor (GP), specialising in lifestyle medicine and nutrition

I run clinics in beautiful sunny Nelson, where I focus on using simple effective strategies to identify, treat, and prevent illness naturally

Many chronic health issues have underlying lifestyle factors - meaning with the right tools and knowledge you can transform your health from the inside out!

I believe passionately that healing and well-being can be achieved through what we eat, how we move our bodies, and how we live our lives


My aim is to share this knowledge with you, to help you on your journey to wellness

Healthcare is not just about the absence of disease - it is the sense of true well-being in every aspect of life.

Work with me

Want to take a balanced yet holistic approach to your health?

I offer individualised lifestyle and nutrition appointments, where we create an targeted, evidence based plan to work on those areas that are bothering you.
