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.

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.
