Such a positive experience at the allergy clinic with Professor Adam Fox. He’s clearly incredibly knowledgeable, but so down to earth, with absolutely no airs and graces. He’s easy to talk to and explains everything in a way that’s clear and easy to understand. All the testing was done on site, there and then, which made the whole process so straightforward. We left feeling informed, reassured and excited to start treatment. Highly recommend!

It took some time of navigating the medical landscape before finding Professor Adam Fox and it was like a breath of fresh air in terms of expertise and knowledge. He listens, is kind, excellent with children and makes you feel reassured. Allergy London in its entirety is well managed and the staff there couldnt be more helpful or supportive. If you have a child with allergy based challenges it is the place to go.

Bringing my teenage son, who has struggled with eczema and allergies for many years, to the Allergy Clinic was something we had hoped would finally bring him some real support, so meeting Professor Fox was genuinely reassuring. Professor Fox spoke directly to my son, encouraging him and helping him understand that there are now clear steps that can be taken to help him. Several tests were carried out with great care and sensitivity, and an initial treatment plan was put in place straight away. Most importantly, my son felt heard. He left the appointment feeling more confident and hopeful than he has in a long time. Professor Fox’s clarity, compassion and professionalism made a noticeable difference. Professor Fox and his team showed great kindness, expertise and a thoughtful approach and turned what could have been a daunting visit into a positive and reassuring experience. Thank you for supporting my son as we begin this journey to better manage his allergies and eczema. They were all brilliant and very kind.

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.

Prof. Fox speaks to BBC News London after Family Shocked and Saddened After Being Refused Service Over Son’s Severe Allergies

Allergy London’s Professor Adam Fox OBE, spoke to BBC News London following a family’s experience in a restaurant after their son was refused service.

Prof. Fox shared “It’s a significant issue for people with food and other allergies when they’re unable to take part in everyday experiences that many of us simply take for granted.

“Just as we wouldn’t consider it acceptable for a restaurant to exclude someone because they use a wheelchair, I’d like to see the same principle applied to people with food allergies. No one should feel excluded from a restaurant or unable to share an experience with family and friends simply because of an allergy.”

A spokesperson for Pizza Express said the restaurant does allow customers with certain allergies to bring their own food, subject to appropriate safety controls. The company apologised for what it described as an isolated incident, acknowledging that its policy had not been implemented correctly and emphasising that inclusivity is at the heart of its approach.
