About Grounded Health

If you’ve been searching for answers for a long time, you’re in the right place.

Hey, I’m Alicia, a degree-qualified nutritionist, wellness coach and founder of Grounded Health.

I know what it’s like to live with chronic health conditions, struggle with symptoms and feel like you’ve tried everything. I was diagnosed with coeliac disease at around four or five years old and juvenile idiopathic arthritis (a type of autoimmune arthritis) at fifteen. There was a time I was in significant pain with joints all over my body inflamed, where I struggled just to walk. I ended up taking very strong medication, just to get my symptoms under control, and being told there wasn’t much more I could do.

I wanted to understand what else might be possible, so I spent years learning about nutrition, gut health, inflammation and the lifestyle factors that can influence our health. That journey led me to complete my Bachelor of Applied Science in Human Nutrition and build a practice around the kind of support I wish I’d had when I needed it most.

Today, I manage my autoimmune arthritis with nutrition and lifestyle alone, without medication. That’s not the path for everyone, but my experience showed me how valuable it can be to understand your body, have the right information, and explore what may be contributing to how you feel.

That’s what I do for my clients.

I work with women navigating chronic gut symptoms, IBS, autoimmune conditions, chronic inflammation, skin issues, and other ongoing health challenges that affect everyday life and your ability to show up for the things that matter.

Whether it’s fatigue, brain fog, bloating, unpredictable digestion, joint pain or symptoms that leave you feeling unlike yourself, I understand how exhausting it can be when you’re not getting the answers or relief you’re looking for.

You might have seen specialists, tried elimination diets, taken supplements and spent hours researching what might help - yet still feel like you’re piecing everything together on your own.

You deserve support that looks beyond the obvious and considers the bigger picture.

Through personalised nutrition and wellness coaching, I take a holistic, evidence-based approach to understanding your health. We start with your whole picture: your history, symptoms, nutrition, gut health, lifestyle and goals to explore the factors that may be influencing how you feel. Where appropriate, functional testing can help us investigate further and guide our next steps.

We build a plan that fits your actual life - not a generic protocol designed for someone else’s body.

I also understand that knowing what might help and actually putting it into practice are two very different things, especially when you’re already dealing with symptoms that make everyday life harder. That’s why ongoing support and accountability are such an important part of my approach.

You’ll have guidance along the way so you’re not navigating it all alone, helping you save time, energy and money by reducing the ongoing trial and error and focusing on what’s most relevant to you.

Working with me looks like:

  • Having clarity on what’s actually driving your symptoms - not just a name for your condition.

  • A personalised plan built around your specific body and circumstances.

  • Sustainable changes that fit your real life, not an overwhelming overhaul.

  • And someone who understands both the physical and emotional weight of managing ongoing symptoms or a chronic health condition - because I’ve been there.

My goal is to help you spend less time guessing and second-guessing yourself, feel more confident in understanding your body, and have a clearer path forward with your health.

I’m based in Christchurch, New Zealand, and work with clients online across New Zealand and Australia.

If you’re ready to stop guessing and start understanding what your body actually needs - I’d love to work with you.

Areas of expertise

Whether you’re living with a chronic illness, navigating an autoimmune disease, managing gut health issues, or trying to build healthier habits, I provide personalised, evidence-informed nutrition and wellness support.

I specialise in helping women with:

  • Nutrition for Autoimmune disease – including rheumatoid arthritis, coeliac disease, psoriasis, Hashimoto’s thyroiditis, and inflammatory bowel disease (IBD)

  • Chronic fatigue and low energy – support for brain fog, poor sleep, and chronic inflammation

  • Digestive health and gut symptoms – including irritable bowel syndrome (IBS), constipation, diarrhoea, bloating, discomfort after meals, and leaky gut (increased intestinal permeability)

  • Building sustainable lifestyle habits – creating routines that support long-term wellbeing, resilience, and symptom management

Your symptoms are not random - they’re messages from your body.

Together, we’ll uncover what those signals mean and identify the root causes behind them. My role as a nutritionist and wellness coach is to guide you in reducing discomfort, restoring balance, and improving your quality of life through holistic nutrition and lifestyle strategies.

With the right tools, you’ll feel more connected to your body - and more empowered to support your long-term health and wellbeing.

  • Working with Grounded Health to improve my gut health has been fantastic.

    Before starting, I’d lived with poor gut health for two years and assumed it was just part of turning 30. It affected both my work and social life. Since working with Alicia, things have dramatically improved, I haven’t felt this good in years.

    I really enjoyed her coaching style; it was the perfect fit for me. She combines practical tips with deep knowledge of gut health, making complex information easy to understand. I appreciated how she focused on the basics of nutrition first, as my understanding wasn’t as solid as I thought. I was surprised to learn that some foods I believed were “good” for gut health weren’t, and with a few simple changes Alicia suggested, my gut health improved dramatically.

    Like many people, I didn’t know how to get back on track. Thanks to Alicia, I feel like myself again. If you’re struggling with gut issues, I highly recommend reaching out to Grounded Health to start your journey toward better health and quality of life.

  • I just completed the 12-week program with Grounded Health and really enjoyed working with Alicia. From the start, everything was tailored to my specific issues and lifestyle - juggling two businesses, parenting, and all the other things that affect how much time I can put into looking after myself.

    What stood out was her empathy and understanding - no judgement, no unrealistic demands. Sessions were relaxed, supportive, and full of practical advice, from mindful eating to planning ahead. I loved that Alicia shared her own experiences with gut health too - it felt like being part of a club rather than being lectured.

    I now have tools, strategies, and a better understanding that there’s no “one-size-fits-all” with nutrition. I find myself planning meals differently, making better choices, and hearing Alicia’s kind voice in my head when I’m deciding what to eat.

    Most of all, I feel supported in my actions. If you’re considering working with Grounded Health, I’d absolutely recommend it. Alicia is approachable, knowledgeable, and makes the whole process feel achievable and personal.
