Your Child’s Allergies: Finding a Way Forward

Does your child struggle with food allergies, eczema, or asthma? I understand how overwhelming these conditions can be for both children and parents—endless sleepless nights, painful flare-ups, and the constant worry of allergic reactions.

As a mother of a child with allergies and a Consultant in Paediatric Allergy and Clinical Immunology, I’ve experienced these challenges first hand. That’s why, at Children’s Allergy Doctors, my team and I are committed to offering expert, compassionate care to help your family find a way forward.


My Experience and Approach to Care

As a Paediatric Allergy Specialist, the Founder of Children’s Allergy Doctors and a Professor at King’s College London, I have spent over two decades advancing allergy care. I have been a Consultant in Paediatric Allergy and Clinical Immunology Evelina London Children’s Allergy Service, one of the UK’s most prominent centres of excellence, and now serve as Medical Advisor to the Natasha Allergy Research Foundation (NARF).

Over the years, I have helped thousands of families through tailored treatment plans that bring relief, reassurance, and long-term improvement.

My passion for paediatric allergy stems from personal experience. My husband has severe asthma and hay fever, and my daughter was diagnosed with eczema as a baby. I understand the frustration, sleepless nights, and emotional toll these conditions bring. These experiences strengthened my commitment to early intervention, empowering families with expert guidance and support to manage allergies effectively and minimise their health impact.


Cutting-Edge Care Backed by Research

Research is central to the care I provide. I have spent years studying how food allergies develop and progress, with a particular focus on peanut allergy in young children. My PhD research at King’s College London explored the early immune responses that lead to allergic sensitisation and how environmental factors—like early environmental exposure to food allergens and skin barrier health—can influence allergy risk. These findings have contributed to preventative strategies, including early allergen introduction for at-risk children, which I now incorporate into clinical practice.

I have co-authored several landmark studies on the prevention of food allergies, including the Learning Early About Peanut (LEAP) and Enquiring About Tolerance (EAT) studies. These pivotal studies demonstrated that early introduction of peanut and egg into a child’s diet can significantly reduce the risk of developing these food allergies, shaping global guidelines on allergy prevention.

Building on this foundation, I led the Pronuts study, a multicentre European research project. The study found that children with a sesame seed or nut allergy can safely introduce an average of nine other nuts or sesame seed into their diet. Importantly, the study showed that this approach is associated with a low rate of new nut or seed allergies over a three-year period, offering families a more hopeful outlook for dietary expansion and allergy management.

Currently, I am co-leading the Stopping Eczema and Allergy (SEAL) study, an international multicentre research initiative across the US and UK. This study investigates how early interventions in children with eczema can prevent the development of food allergies, aiming to improve early prevention strategies for at-risk children.

Additionally, I served as an investigator on ground-breaking trials at Evelina London Children’s Hospital, including oral peanut immunotherapy and peanut patch desensitisation trials. These studies are advancing our understanding of how desensitisation treatments can reduce severe allergic reactions, offering safer long-term options for children with peanut allergies.

Because I stay actively engaged with the latest advancements, your child will benefit from cutting-edge treatments designed to reduce symptoms and risks. I also contribute to the development of international best practices, having co-authored the European Eczema guidelines and other publications.

For those interested, a full list of my published guidelines and research articles is available here.

Beyond research, I have held key leadership roles within the allergy and immunology community. I served as President of the Royal Society of Medicine Allergy and Immunology Section (2022–2024) and was Paediatric Chair for the European Academy of Allergy and Clinical Immunology (EAACI, 2019–2022). These roles enabled me to guide research priorities and influence clinical practice across Europe and beyond, ensuring families benefit from the latest advancements in allergy care.


Achievements and Recognition

Helping families overcome these challenges has been my life’s mission. My dedication to being a paediatric allergy specialist has been recognised with several prestigious awards, including:

  • Health Professional of the Year from Coeliac UK,
  • The Barry Kay Award for Excellence in Paediatric Allergy Research from the British Society for Allergy and Clinical Immunology, and
  • The Distinguished Clinician Award from the American Academy of Allergy, Asthma & Immunology.

I regularly present my research at national and international conferences to ensure that best practices continue to evolve and improve. While these honours are gratifying, what truly drives me is seeing families feeling reassured, informed, and empowered to navigate their child’s allergies with confidence at Children’s Allergy Doctors.


What to Expect from Our Care

At Children’s Allergy Doctors, our paediatric allergists provide child-centred consultations that allow plenty of time to discuss your concerns and fully address your questions. We have extended our new appointment times to 45 minutes instead of 30 minutes that most care providers offer.

After each visit, you’ll receive a comprehensive consultation letter within 24 hours, summarising everything we covered and providing you with a roadmap for managing your child’s condition at home.

After your clinic appointment, we continue to care and provide rapid responses for any queries you may have including on the weekend and bank holiday for urgent queries. We additionally have a free nursing helpline from 9-3pm week-days to add an additional quality measure for your care.

You can expect a holistic approach from our paediatric allergy service that combines the latest research, clinical expertise, and compassionate care.

Paediatric Allergy Specialist Training

My training as a paediatric allergy specialist has taken me through the UK’s leading paediatric hospitals, including Guy’s and St. Thomas’, Great Ormond Street Hospital, and King’s College Hospital.

I hold dual accreditation in General Paediatrics and Paediatric Allergy, as well as a European Paediatric Allergist certification and advanced degrees (MSc and PhD) in allergy research.
