About Dr Diab Haddad

Dr Diab Haddad is an experienced Consultant Paediatrician with over two decades of expertise in allergic and respiratory disorders. He has led the Respiratory and Allergy Service at St Peter’s Hospital in Surrey for more than 20 years, providing highly specialised care for children with complex respiratory symptoms, asthma, food allergies, anaphylaxis and other immune-mediated conditions.

After completion of his undergraduate medical training, Dr Haddad enrolled in paediatric training in Jordan and Scotland. He was appointed as a Consultant Paediatrician in London in 1997. He has held honorary consultant positions at both the Royal Brompton Hospital and St Thomas’ Hospital, further strengthening his expertise in paediatric respiratory and allergic disease. He is also an Honorary Senior Lecturer at Imperial College London.

An active contributor to research and medical education, Dr Haddad has authored numerous publications on topics including anaphylaxis, nut allergy and diagnostic allergy testing. He has written several book chapters and served as editor for a paediatric textbook.

With a broad general paediatric background and specialist knowledge in allergies and respiratory medicine, Dr Haddad offers a comprehensive and integrated approach to children’s healthcare. He is known for his ability to consider the child’s symptoms holistically, reducing the need for multiple referrals and increasing the likelihood of reaching a clear, unifying diagnosis.

Having worked within healthcare systems across several countries, Dr Haddad brings a deep appreciation for the importance of the doctor–family relationship. He places great emphasis on listening to children and their families, recognising that their lived experience often holds the key to understanding the condition and guiding effective treatment.

We consulted Dr. Diab about my daughter's prolonged respiratory issues, and he was great. He listened patiently and took the time to understand her 3-year-long history. He clearly tries to get to the true picture and asks the right questions to do so. He explained what could be going on and outlined the next steps in her treatment plan in a clear, reassuring way. He is knowledgeable and well-versed in his field. I would highly recommend him for answers to your child’s respiratory issues history.

Very successful routine follow-up appointment monitoring my son for respiratory /allergies. We left reassured and clear on next steps. We also had the opportunity to look at my son’s overall holistic development and discussed the onset of puberty - very helpful and useful. Dr Hadad has been monitoring our child for 12 years now. We first came to Dr Hadad because our son was premature, born at 33 weeks. He had numerous health complications and Dr Hadad guided and supported us through it all - respiratory and severe peanut and egg allergy. As my son developed, Dr Hadad was our constant source of reassurance and he always gave the best, timely advice as other challenges arose with breathing difficulties/asthma/other allergies/whooping cough/developmental concerns. We can’t thank Dr Hadad enough for what he had done/continues to do for our family. He is an extremely experienced, kind and empathetic consultant and we recommend him highly.
