Dr Diab Haddad is kind and thorough in his care. He gives clear explanations for diagnoses and treatment plans. This professional approach puts children and families at ease. Dr Haddad offers strong support regarding allergies.
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 thorough and professional. Felt in very safe hands.
Informative and supportive and gave us reassurance by booking in a prompt follow up appointment
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.
Dr Diab, was very calm and methodical and gave us lots of time to try to get to the bottom of the problem
Very helpful and professional. Hopefully has solved our problem.
Gary Steifel is an excellent paediatric allergist. He is very knowledgeable and has a calm, child-centred approach. I would not hesitate in recommending him.
