Meet Tonia our
Functional Medicine specialist

Since becoming a Functional Medicine Practitioner, Tonia has seen just how many people are living with long-term chronic pain and complex health conditions. Far too often, these individuals fall outside the scope of our conventional acute-care model and are told, “There’s nothing more we can do—you’ll just have to live with it.”

Tonia fundamentally rejects this idea. She believes that by addressing the root causes of imbalance—and by making strategic lifestyle, nutritional, and environmental changes—most people can experience meaningful improvements in their health, vitality, and overall well-being.

Frequently Asked Questions
About Functional Medicine

Functional Medicine is an integrative, science-based approach to healthcare that seeks to uncover the underlying causes of illness rather than simply treating symptoms.

It combines the best of conventional medicine and natural therapies to create a comprehensive, personalised treatment plan.

Our practitioners explore how genetics, nutrition, environment, and lifestyle interact to influence your health — empowering you to take an active role in your healing journey.

Functional Medicine is ideal for those who want answers to chronic, unexplained, or recurring health issues that conventional medicine alone has not resolved.

Your journey begins with an in-depth consultation and health assessment. We take time to understand your full medical history, lifestyle, nutrition, and current symptoms.

During your assessment, we may include:

  • Comprehensive health questionnaires
  • Advanced laboratory or functional testing (hormones, gut microbiome, food sensitivities, nutrient levels, etc.)
  • Personalised nutrition and supplement recommendations
  • Lifestyle and stress management guidance

You’ll receive a customised treatment plan that focuses on rebuilding balance and supporting long-term healing — not just temporary symptom relief.

Every plan is as unique as you are — grounded in science, guided by nature, and built for lasting wellness.

Functional Medicine focuses on identifying and addressing the root cause of illness, not just masking symptoms. It takes a systems-based, personalised approach that considers nutrition, lifestyle, and environment.

Yes. Functional Medicine uses modern diagnostic tools, advanced lab testing, and peer-reviewed research to inform each treatment plan.

Anyone struggling with chronic or recurring health issues — especially when conventional treatments haven’t provided clear answers — can benefit from Functional Medicine.

This depends on the complexity of your condition, but many patients start noticing improvements in energy, digestion, and sleep within a few weeks. Long-term results come with consistency and commitment.

Absolutely. We encourage collaboration and can integrate our recommendations with your existing medical care for a cohesive, safe approach to wellness.
