Work with Dr Brad Leech
Root-cause care for people at every stage of life from settling an acute flare, to managing a chronic condition, to optimising how you feel and how long you stay well. Evidence-based, deeply personalised, and built around your whole story.
The approach
Understanding the whole story
A symptom is rarely the whole picture. I take the time to understand your full health history your timeline, what you've already tried, and how it all connects using advanced microbiome science and a deep understanding of the immune system to find the drivers beneath ongoing symptoms.
The result is a clear, practical plan across diet, lifestyle, and where it helps supplementation, without the overwhelm. I work alongside your GP and specialists, and with people at every stage of life, from newborns to older adults.
How I practise
Science, food, and the whole person
01
Evidence-based
I stay at the forefront of the research and bring it into the room so your care reflects what the science actually supports, not the latest trend.
02
Functional nutrition
Food first. A thorough look at what's on your plate uncovers the deficiencies and imbalances behind symptoms, and shapes a nutrition plan built for your body.
03
Integrative care
Bringing together the best of complementary and conventional medicine in a genuinely integrated way, working alongside your wider healthcare team to address the root cause.
Who I work with
From acute care to chronic management to longevity
Much of my work is with complex, chronic, and often misunderstood conditions but the door is open far wider than that. I work with people right across the spectrum of health: settling an acute flare, managing a long-term condition, and, increasingly, helping people who already feel well optimise their health and extend their healthspan.
That spectrum has a name in my practice — The Method by Dr Brad Leech, a framework that scales the same foundations across three tiers, Restore, Manage, and Optimise, and moves with you as you progress toward longevity.
Wherever you are on that journey, there's a place to start.

The gut is where I've spent my career in research and in the clinic. Using advanced microbiome testing and a root-cause approach, I work with people to understand what's actually driving their symptoms and to rebuild digestive health from the ground up, rather than chasing one symptom at a time.
IBS, Reflux, GORD, SIBO, Dysbiosis, Bloating, Chronic constipation, diarrhoea, Food sensitivities, intolerances, Crohn's disease, Ulcerative colitis, Coeliac disease, Diverticular disease, Increased intestinal permeability
-
Autoimmunity rarely arrives alone, and it's rarely simple. I support people living with autoimmune presentations by working at the root across the immune system, the gut, and the drivers of inflammation always alongside your GP and specialists.
Hashimoto's, Graves' disease, Coeliac disease, Rheumatoid arthritis, Psoriasis, Ankylosing spondylitis, Lupus (SLE), Multiple sclerosis, Type 1 diabetes, Sjögren's syndrome, Alopecia, Recurrent infections
-
Hormones shape energy, mood, skin, cycles, and fertility. Through nutrition, lifestyle, and carefully targeted support, I help people find steadier hormonal balance from the first period to pregnancy and through menopause.
PMS, PMOS, Endometriosis, Thyroid health, Perimenopause, Menopause, Preconception, pregnancy, postpartum
-
Skin often reflects what's happening inside. Rather than working on the surface alone, I look for the internal drivers gut health, diet, and inflammation behind persistent skin concerns, so the change holds.
Acne, Eczema, Dermatitis, Psoriasis, Hives, Rosacea, Fungal presentations
-
I support the foundations of metabolic health blood sugar, cholesterol, weight, and the inflammation beneath them with food and lifestyle changes that are realistic to actually sustain.
Blood sugar & insulin resistance, High cholesterol, Blood pressure, Metabolic syndrome, Non-alcoholic fatty liver, Weight & body composition
-
Infants and children aren't small adults. I support healthy microbiome development and resilience from birth through childhood and often the whole family alongside them, because health habits are built together.
Infant & child microbiome, Eczema & allergies, Recurrent infections, Digestive concerns, Food intolerances, Immunity, Fussy eating
-
Fatigue, stress, and low mood are among the most common reasons people come to see me. I work with the nervous system and the gut–brain axis to rebuild energy, steadiness, and resilience not just push through.
Fatigue & low energy, Burnout, Stress resilience, Sleep, Gut–brain & mood, Focus & clarity
-
For busy, driven people who already feel well and want to stay that way and get more from their body. This is evidence-led optimisation of the foundations, advanced testing to see beneath the surface, and the practices that extend not just how long you live, but how good you feel in those years.
Healthspan & longevity, Microbiome optimisation, Advanced biomarker testing, Energy & performance, Preventative health, Healthy ageing
Across every stage of life
The same method, scaled to the person in front of me
Infants aren't small adults, and longevity isn't the same project at seventy as it is at thirty. I care for people at every stage of life and tailor the approach to each.
0–12 years
Paediatric
Microbiome development, digestion, immunity, allergies, eczema, and food intolerances in infants and children.
The growth years
Teenagers
Nutrition and lifestyle through adolescence — hormones, skin, energy, mood, and healthy habits.
The middle years
Adults
Gut, autoimmune, and hormonal presentations, fatigue, stress, and chronic inflammation.
Before & after birth
Pregnancy & postpartum
Maternal microbiome, nutrient status, and recovery — supporting both mother and baby.
Healthy ageing
Older adults
Gut–brain health, immune resilience, and the metabolic shifts of ageing well.
Feeling well, aiming higher
Longevity & healthspan
Healthspan, microbiome optimisation, energy and performance — for those already well who want to stay that way.
What working together looks like
Thorough, clear, and never rushed
Most people complete a microbiome test before their first consultation, so we start with real data, not guesswork.
01
It often begins with testing
A genuinely thorough history, your timeline, what you've already tried, and how it all connects.
02
We start with your whole story
I translate complex results into plain language and a clear picture of what's driving your symptoms.
03
We make sense of it together
After your consultation, targeted blood tests, continuous glucose monitoring, or other functional pathology, only when it will sharpen the plan.
04
We test further where it adds value
I collaborate openly with your GP and specialists, because the best outcomes are shared.
05
We work as a team
What you'll leave with
-
The very first thing you'll leave with: a clear, personalised interpretation of the key factors driving your health presentation — drawn from your available pathology and a thorough health evaluation.
-
Built around diversity, not restriction — I focus on what you can eat. The prebiotics best suited to you, the right amount of protein for your needs, and clear guidance on the foods to include and the ones to ease back on.
-
Practical changes across sleep, stress, movement and more — tailored to your individual needs and what's realistic in your life.
-
Where they're genuinely needed: targeted, TGA-approved practitioner-grade supplements, each with a clear explanation of why you're taking it — plus a review of anything you're already taking.
-
Rather than support between appointments, you'll leave with a considered plan and a clear direction — a roadmap for your next steps and future visits.
Every plan is built around your goals, your history, and the realities of your life, not a template.
Microbiome Testing
Completing a microbiome test before your first consultation means we start with real data rather than guesswork and for gut and digestive concerns. Using advanced metagenomic stool testing, we map the bacteria in your gut at species level uncovering dysbiosis, inflammation, short-chain fatty acid production, and the microbial drivers behind your symptoms.
Order through the testing pathway and your results will be ready to review in your appointment.
Other pathology
Want to go further before your initial appointment? Depending on your situation, I can help you choose the most useful tests these may include: Hair tissue mineral analysis , Continuous glucose monitoring, Detoxification & heavy-metal profiles, Hormonal panels, Vitamin & mineral status and bloods, Mould & mycotoxins · And other contributing factors
Get in touch and I'll advise the best tests to organise so your results are ready in time.
Wherever you are on the journey, there's a place to start.
