  • Prof. Lack is one of the most knowledgeable in his field. Being under his care at the Allergy Centre of Excellence (ACE) and completing the OIT program he recommended was critical for treating our son’s allergies. As a result, our son’s allergy was reduced such that he can safely consume some of the allergen. Prof Lack’s plan of introducing the other common allergens was key to preventing our son from developing additional allergies. We couldn’t be more thankful.
