Jake works across the full spectrum of childhood nutrition and growth concerns, each supported by evidence based strategies that strengthen development and build long term health.
Healthy Eating
Personalised children’s nutrition therapy to support healthy growth velocity, improve nutrient status and help your child progress with confidence.
Nutrient Deficiencies
Targeted dietary intervention to correct low nutrient levels, enhance absorption, restore energy and support the biological systems that drive healthy development.
Behaviour Dysregulation
Evidence based nutrition addressing blood sugar instability, micronutrient gaps and gut‑brain pathways to support calmer behaviour, steadier emotions and improved daily functioning.
Recurrent Illness
Structured nutrition therapy to strengthen immunity, improve resilience, reduce frequency of infections and support a child’s overall health foundation.
Feeding Difficulties
Comprehensive nutrition support to expand food variety, improve intake, reduce mealtime stress and ensure your child receives the nutrients required for healthy growth.
Iron & Vitamin D Deficiency
Targeted nutrient correction to optimise iron and vitamin D levels, support energy, improve cognition and strengthen long term developmental outcomes.
Nutrition influences growth, immunity, behaviour, cognition, and long term development, yet many families spend years managing symptoms instead of addressing the underlying nutritional and developmental drivers.
Jake’s clinical approach starts with a thorough intake covering your child’s current symptoms, health history, diet and builds a plan specific to their nutritional and developmental needs rather than a generic diet.
Whether you have tried everything, or you know something is wrong but have never been given answers, this is the level of care that finally moves the needle.

Every child goes through a structured clinical nutrition process, not a one size fits all protocol.
01
Deep-dive intake assessment
A thorough review of your child’s full symptom history, developmental timeline, current investigations, medications and diet. This is the foundation that everything else is built on.
02
Root cause identification
Rather than managing symptoms, Jake looks for the actual driver, whether that is micronutrient insufficiency, gut–brain imbalance, blood‑sugar instability or an undiagnosed developmental nutrition pattern.
03
Personalised children’s nutrition plan
A structured eating plan tailored to your child’s specific nutritional needs, lifestyle, not a restrictive template but a liveable clinical strategy that supports long‑term growth, development and daily wellbeing.
04
Your child’s goals are the engine of their results
Jake and yourself will define your child’s short and long term dream goals, and the projections will be built with clinical precision to take them exactly where they need to go.
05
Ongoing monitoring & expansion
Regular reviews to track progress, adjust your child’s plan and expand dietary freedom. The goal is always the broadest possible diet that supports long‑term growth, emotional regulation and daily wellbeing.

No, you do not need a referral from your GP before seeing Jake for your child. Many families come in with growth concerns, behavioural changes, nutrient‑related symptoms or no clear explanation for what is going on. Jake will conduct a thorough intake, review any existing investigations, and may recommend further testing where appropriate.
Jake’s approach is different because he doesn’t follow generic guidelines or symptom‑management pathways. A GP provides broad medical oversight and a dietitian often works within standard nutrition frameworks, Jake focuses on what is actually driving the problem, not just what your child is eating.
No, your child will not be placed on a highly restricted diet. Jake’s approach is structured, personalised and clinically guided, but it is designed to be sustainable and flexible. The goal is to support your child’s growth and overall wellbeing while keeping their diet as broad and enjoyable as possible. Children actually gain more dietary freedom over time, not less.
Most children begin noticing meaningful changes within the first few weeks. Improvements often include better energy, more stable eating patterns, clearer focus and a stronger sense of structure around what their body and brain need. Growth and developmental shifts evolve over time, but the behaviours that drive better regulation, learning and wellbeing begin shifting almost immediately. Jake monitors your child’s progress closely and adjusts the plan so they continue moving forward with confidence.
Yes. Jake regularly works alongside GPs and paediatric specialists to create a fully integrated plan for your child. Your doctor manages diagnosis, medical monitoring and any required investigations. Jake builds the nutrition and lifestyle strategy that strengthens your child’s growth, behaviour, energy and long‑term wellbeing.
Jake combines world‑class expertise as a children’s nutritionist with extensive experience supporting children with growth concerns, behavioural challenges, nutrient deficiencies and complex developmental needs. His approach gives families a clear clinical advantage built on precision and measurable results.
