Welcome to Allergy and Asthma of Illinois. With our main office in Peoria, as well as 3 conveniently located satellite offices, we are able to offer patients young and old the services they need to breathe easy.

It is important to see an allergy specialist if you or your child has:

  • a chronic cough
  • a history of wheezing or other breathing difficulties
  • been diagnosed with asthma requiring routine or frequent medicines
  • been to the ER or hospitalized for possible asthma
  • nasal congestion or drainage that needs frequent medication
  • persistent or frequent eczema / atopic dermatitis
  • a systemic reaction to stinging insects
  • recurrent infections
  • food allergy
  • hives

We welcome the opportunity to meet with you, your child, or other loved one to diagnose and treat your problem. Don’t let asthma or an allergy limit the quality of your life!
