ABOUT
Longevita Wellness & Dione Simmons
Science-led naturopathy for people who are ready for real answers.
Live Long. Live Well.
Welcome to my practice.
I'm Dione (She/her) but you can call me Dee.
I created this clinic for people who are ready to feel better but who need more than surface-level support. If you've been told everything looks "fine" but you know something isn’t or if you’re feeling overwhelmed, unwell or unheard, I want you to know you're not alone and you're in the right place.
I’m a naturopath and functional medicine practitioner with over 15 years of clinical and wellness industry experience; working across Australia, Asia, Europe and the US. Operating primarily online from my little clinic in Regional Victoria, I work with people across Australia to uncover the root causes of their health issues, support and help them to make long-term, sustainable progress.
Longevita Wellness is an evidence-based natural and holistic healthcare practice with patient centred care in mind; built on the belief that every person deserves to feel good in their body and be empowered with the tools to heal their own health.
How It All Started
Growing up, I lived with severe eczema, asthma and chronic tonsillitis. I was constantly unwell and uncomfortable in my body, relying on frequent courses of steroids and antibiotics. Being sick felt normal but it never felt right.
As a teenager, I moved from Australia to Italy and it was there that my understanding of health changed completely. After another tonsillitis flare-up, I visited a GP expecting the usual antibiotic prescription. Instead, I was given a herbal medicine tonic. I remember thinking it was strange and honestly, I was a little doubtful.
However within two days, I had recovered. No gut upset. No diarrhoea. No lingering side effects.
Over the period I lived abroad, I saw several doctors for various ailments and each time I was offered holistic, root-cause–focused care rather than symptom suppression. Each time, it worked. What puzzled me most was why healthcare in Australia was practised so differently.
When I eventually returned home and discovered that naturopathic and Integrative medicine encompassed the very principles that had helped me restore my health, I knew this was my calling. I wanted to help others by treating the whole person, at the root cause.
I went on to study a Bachelor of Health Science, majoring in Naturopathy (Herbal Medicine and Nutrition), graduating in 2013. I opened my first clinic with a clear intention: to deliver natural medicine with the same rigour, professionalism and evidence-based approach expected in conventional healthcare, without the “woo woo.”
Since then, I’ve supported thousands of clients to resolve complex and chronic health concerns, balance hormones, restore gut health, reduce inflammation and most importantly, rebuild trust in their bodies.
What Sets This Practice Apart
Since 2013, I’ve been an active contributing member of the science for the global supplement and natural health industry. I’ve led research and product development for major brands, I’ve set up Medical Advisory Boards, I’ve overseen clinical trials and have had the privilege of working with numerous global thought leaders and researchers in natural medicine.
Some of the brands I’ve contributed to include:
-
One of the original team members driving innovation, international go to market strategy and scientific marketing over 5 years.
-
Led the brand reformulation consulting with Paediatric Nutrition Specialists and Department heads at a number of Children’s Hospitals to maintain Pentavite as Australia’s most trusted paediatric vitamin brand for treating failure to thrive.
-
I was the Head of Science, overseeing clinical trials and product innovation.
-
I set up the dietary supplements division, leading a cross functional team to create several brands, their strategies and formulations including IM8.
-
Serving as the Head of Product for this global longevity startup, driving the innovation blueprint, Quality Assurance and Regulatory Compliance.
Through these roles, I’ve learned how to critically assess therapeutic materials, manufacturers and gain an appreciation of how critical the manufacturing process is in ensuring a product works.
Lets just say not all materials and brands are created equal and it is important to look past marketing and hype. It’s why my clients trust me not just to recommend the right treatment, but to explain why it works and how to use it with confidence.
My Personal Mission
While I love developing impactful products for the health industry, working one-on-one with people who are ready for change but unsure where to begin is just as meaningful to me.
Because I’ve been that person too.
I’ve experienced several chronic health challenges over my life from gastritis that left me unable to eat anything other than 3 foods, to debilitating eczema and recurring tonsillitis; to infertility and recurrent miscarriages when trying to fall pregnant. I know what it’s like to be told nothing is wrong when everything feels wrong.
I also know what it takes to rebuild. And that’s what I offer every client I work with. A realistic plan centred around you, built with integrity, empathy and drawing on the latest science.
This clinic is not a revolving door and I don’t believe in over-servicing or dependency. I believe in empowering you with the right tools, the right plan and the right level of support so you can move forward with confidence.
My Values Are at the Heart of Everything I Do
Empathy
I meet you exactly where you are, physically and emotionally. Every consult is a safe, non-judgemental space where your lived experience is respected and validated.
Integrity
I only recommend what’s necessary and I always explain why. I never push products or treatments you don’t need and I work hard to keep care accessible.
Inclusivity
Longevita Wellness is a neuroaffirming and LGBTQIA+ inclusive practice. I welcome people from all backgrounds, identities and health journeys.
Excellence
With over 15 years of global experience and continuous clinical education, I bring a high standard of care, strategy and insight into every consultation.
Collaboration
I often work alongside GPs, specialists and allied health professionals to ensure you receive integrated, coordinated care.
Empowerment
This is a partnership, not a prescription. You’ll leave each session with real knowledge, practical steps and a clear understanding of your next move.
What Clients Say

If you’re feeling stuck, exhausted or frustrated with your health but you’re not sure where to start, I offer a free 15-minute Discovery Call to help you explore your options.
You’ll get honest feedback, a sense of the process and a chance to ask questions with no obligation to book. It is a good opportunity to see if I’m a right fit for you or discuss if I think an alternative practitioner or modality may be better suited. You’ll always walk away with an actionable next step.
