Advanced Allergy & Asthma Associates/Food Allergy Center of Illinois is a respected medical practice, serving residents of Northern Illinois with three conveniently located offices, in Crystal Lake and Elgin. Our practice was founded on the simple principles of compassion and customer service, blended with the advanced science of modern medicine.

Our physicians and staff members are highly trained, skilled, and deeply caring individuals. Our patients are our friends and neighbors, whom we think of as our extended family. We strive to deliver the same quality of care and level of service that we would want our own beloved parents, children, or other family members to receive.
