A Bit About Us!


We work with your family doctor to help you and require their referral. Our office consults on adult and pediatric patients of all ages for various conditions. Our dedicated staff at Hamilton Allergy work tirelessly to provide the highest quality services in diagnosing and treating a wide range of allergic conditions.

Our office focuses on respiratory allergies involving the nose and chest, allergic skin conditions such as dermatitis and urticaria, multiple presentations of immediate and delayed food allergies, allergic reactions to stings and bites, and adverse drug reactions. Allergic conditions are diagnosed based on your history, examination, allergy testing and when needed, an allergen challenge to ultimately improve your quality of life.

Our office is also dedicated to the advancement of new therapeutics in the field of allergy and immunology. There are several clinical trials ongoing for various allergy and immunology conditions. Please do not hesitate to contact us if you are interested in one of these trials!
