The team at Allergy London are the best I have come across in terms of knowledge on allergies within children and young people. I had an excellent experience as they treated my son. Their advice and their knowledge are excellent.

Excellent team - we had a great session with Professor Dr Adam Fox. Very informative, reassuring and listened well without dismissing any of our queries or worries. Provided invaluable advice, especially when we're overwhelmed by all the information online; so it was really good to be able to get sound medical recommendations and know what our next steps are for our baby. Thank you to all!

The team are brilliant and I would highly recommend them. My son has done peanut desensitisation with them. When he first started he was one of the most sensitive-to-peanuts children they had seen in the program. He is now able to consume 1.5 peanuts, which is amazing progress and means he is much safer when we go out. Professor Fox, Dr David and Nurse Victoria are all incredibly helpful, pro-active and flexible with suggestions and troubleshooting - our family is immensely grateful to them for all their help and support.

Cannot recommend Dr Adam Fox highly enough. With his unrivalled knowledge he is enabling our son to have hope that some of his multiple food allergies may be eventually eliminated, where before there was only fear. His patience and kindness with children is amazing. His advice and plan of action is truly life changing and will be appreciated always. We traveled from abroad just to see Dr Fox and the distance/effort was definitely worth it.

Dr Fox, Dr Mass and the entire team have been fantastic in taking care of our son who had multiple and sever food allergies. We cannot believe how far we have come, with the support of these incredible specialists.
We never thought that our son would be able to get to a stage where he can now tolerate large quantities of foods he was so allergic to as a baby. This has only been possible due to the desensitisation protocols provided so expertly by Dr Fox and his team. We are so incredibly grateful as it has genuinely been a life changing process.
