Welcome to Your Lifestyle Medics

It is founded and led by Dr Marissa Kelaher, a qualified practicing medical doctor, who has a fellowship in General Practice (FRNZCGP), and is registered with the New Zealand Medical Council.

Dr Marissa has extensive additional training in Lifestyle Medicine; Nutritional and Environmental Medicine; and Integrative Health, and is completing fellowship through the Australasian Society of Lifestyle Medicine.

She has a passion for teaching people how to improve their health naturally, through the Your Lifestyle Medics online courses, ebooks, blog posts and social media.

Dr Marissa also regularly runs health workshops, and speaks at retreats and events New Zealand wide.

What is Lifestyle Medicine?

Lifestyle Medicine takes a whole-person approach to health, addressing all the factors that impact on our wellbeing.

It flips healthcare upside down. Rather than relying on pills and procedures to control symptoms, it aims to improve wellbeing from the inside out.

Lifestyle Medicine is highly evidence based and recommended by health experts around the world as a way to prevent, treat, and potentially even reverse illness.

Lifestyle Medicine does not rely on expensive supplements, subscriptions, or diet plans. It is simple, achievable, highly sustainable, and affordable!

The team

Dr Marissa Kelaher

MBChB, DCH, FRNZCGP, ASLM, ACNEM

I’m Marissa, a GP and Lifestyle Medicine doctor in beautiful Golden Bay, New Zealand. I discovered Lifestyle Medicine after wanting to be able to offer people an evidence-based holistic natural approach to health.

Specialising in holistic health consultations, I like taking an in-depth look at your current health and future goals, and creating a highly tailored plan to help you achieve optimal health and wellbeing.

I am a Fellow of the Royal NZ College of General Practitioners, with additional training in Lifestyle Medicine, and am currently completing a Fellowship with the Australasian Society of Lifestyle Medicine.

My completed postgraduate education includes nutritional and environmental medicine; integrative peri/menopause wellbeing; nutrigenomics; metabolic and heart health; longevity; and thyroid and adrenal conditions.

Tests I use include nutrigenomic (DNA) testing, gut microbiome testing, and other functional tests if needed and desired, and have a special interest in personalised precision medicine, and mind body medicine.

I enjoy helping and empowering people to regain control of their health. I can help with hormonal health issues, heart health, gut health, autoimmune disease, metabolic health, thyroid and adrenal health, holistic mental wellbeing, and non-diet weight management.

My clinics are fully online (virtual appointments only), Wednesday to Friday.

I live with my husband and two homeschooled boys. Outside of work I enjoy outdoor adventures, travel, yoga, music, photography and gardening. I have travelled to over 80 countries around the world, with many more on my list ❤️

I look forward to helping you on your journey to better health!

PLEASE NOTE: I am not taking on any new patients at present (as of January 2025).
