Hey there, I'm Celine!

I'm a holistic nutritionist with a serious passion for getting to the root cause of your bloating, because band-aid solutions are not cute!

I promise you this: you can live bloat-free without a restrictive diet, without endless supplements, and without being told your only option is to "learn to manage it."

Behind her, there are wooden shelves with decorative items such as a black teapot, white abstract sculptures, and a mirror. To her left, there is a white side table with a silver vase holding white flowers, and a small white pedestal with yellow lemons.

Let me guess: you're here because you're done guessing. Done Googling. Done cutting out foods and hoping this time it'll stick. You've tried everything the internet has told you to try and you're still waking up bloated, still dreading meals, and still no closer to feeling like yourself.

You're more than ready for an approach that will get to the root of your bloating once and for all.

You're not alone.

Every day I work with women who arrive exactly where you are;
done with trial and error, done being dismissed, and carrying that last quiet flicker of hope that something will finally work.

I was once that woman too.

You're tired of cutting out foods, spending money on supplements that don't work, and waking up bloated anyway. You need someone who actually looks at why. It's about time we met.

My superpower is connecting the dots between your gut, your stress, and your nervous system

because that connection is usually the missing piece.

For most of my life, my gut was running the show…
and not in a good way.

Daily bloating, stomach pain, unpredictable digestion, no matter how clean and healthy I ate. I cut out gluten, cut out dairy, spent thousands on supplements that never did much, saw every specialist. And every time, I walked away with either a “take probiotics and add fiber” or a longer list of foods to avoid forever. Eventually, a doctor handed me an IBS diagnosis, a pamphlet, and absolutely zero support on what to actually do with it. 

I sat in my car afterwards thinking: this cannot be it.

That stubborn belief that I wasn't supposed to live like this is what changed everything.

When I started working on my stress and nervous system through personal development, my gut started to calm down. Not dramatically at first, but enough to make me ask a question nobody had ever asked me before: what if this isn't just about food?

That question sent me straight into studying Holistic Nutrition, not for a qualification, but to heal myself.
To find the missing piece all GP and specialists had missed.
And what I found changed everything: the gut is in constant conversation with your nervous system, your stress, and your mindset. No elimination diet alone will ever fix a gut that's also being driven by chronic stress and a dysregulated nervous system.

She has a slight smile and is standing beside a white shelf with decorative items and a small side table with a vase of white flowers.

That was my aha moment. And once I saw it, I couldn't unsee it.

I applied this whole-body approach to my own healing and for the first time in my life, things actually shifted. The bloating eased and I reintroduced foods I thought I would never be able to eat again. I started saying yes to dinners out. I ordered the pasta.

I healed my gut without giving up the foods I love.

Now as a Registered Holistic Nutritionist specialising in gut health, I help women do the same, without the years of trial and error I had to go through first. Because the women I work with every day aren't doing anything wrong. Nobody has ever looked at the full picture with them. That's exactly what I’m here to help you do.

Oh, and outside of helping women heal their gut, you'll find me at brunch with people I love, lost in a romantasy novel, lifting weight at the gym or at my fav Reformer Pilates classes or soaking some Vitamin D on the beach. And I am a massive dog lover, but who isn’t, right!!

The Why Behind It All…

I believe your body isn't broken. It's just been misunderstood. And after years of being told to just cut out more foods and manage your symptoms better, I completely get why it feels that way.

I believe gut health has almost nothing to do with finding the "right" diet. Your stress, your nervous system, your mindset are all talking to your gut, constantly. And nobody is listening to that conversation. That's the problem.

I believe cutting out more foods is not the answer. I've been there. The list gets longer, the gut gets more reactive, and the hopes get smaller. It’s a never ending cycle. But it doesn’t have to be this way!

I believe food is one of life's greatest pleasures (I see you foodie, welcome to the club!)  and you deserve to experience it that way. Not with anxiety, not with a side of regret, and definitely not while Googling your symptoms at midnight in pain...

I believe women deserve better than a 10-minute GP appointment that leaves you more confused. You deserve someone who actually looks at the full picture. That's exactly why I do what I do.

And I truly believe healing is possible for you, even if you've tried for years and nothing has worked (yet!). I was that person, my clients were that person. I promise you, food freedom exists for you too. 😊

If you've ever sat in a doctor's office, walked out more confused than before with zero answers, and quietly thought "there has to be a better way"

Are you next?

One of my clients came to me after 15 years of reflux after every single meal. She'd tried everything, specialists, diets, supplements, and nothing had worked. Within one week of following my personalised recommendations, her reflux had completely disappeared.

One week. After 15 years of suffering.

That's what becomes possible when someone finally looks at the full picture, your gut, your stress, your nervous system, instead of just handing you another list of foods to avoid.

Your story could be the next one we celebrate.
