Reassuring and excellent insights into how to support my daughter with her allergy
I did not see professor Lack at this appointment specifically but am so glad he recommended us for the OIT program previously
I have seen Professor Gideon Lack three times and he has always been open, clear and supportive in my daugther’s allergy journey. He is very thorough, knowledgeable and explains solutions, issues and next steps in a simple concise manner. Our recent visit was to understand dairy allergies and through a series of various tests we were able to pinpoint next steps. His support staff are also professional, timely and supportive when dealing with queries.
Professor Lack is personable, professional and thorough. My son has multiple allergies; tackling this is daunting for any parent, but we feel we are in safe hands with Professor Lack.
Very efficient and thorough allergy program for my son.
We have seen Professor Gideon Lack as our daughter has eczema and we were worried if she would develop food allergies. Professor Lack has been extremely helpful, extremely knowledgeable, kind and caring. We wish we only found him earlier as getting educated about food allergies early is very important in order to avoid potential allergies in children.
One of the greats of paediatric allergy. I have never had a disappointed shared patient to date. Exceptional skill set.
