Allergy, Asthma & Immunology

Allergy, Asthma and Immunology focuses on diagnosing and treating the symptoms of allergies, respiratory conditions associated with asthma and primary immunodeficiency disease (PIDD).


Patients will find relief from allergic symptoms by undergoing necessary testing to find the root of their discomfort. Proper testing and diagnosis can save the life of an allergy sufferer.

Common allergies include:

  • Drug allergy
  • Eye allergy
  • Food allergy
  • Hay Fever
  • Latex allergy
  • Mold allergy
  • Pet allergy
  • Sinusitis
  • Skin allergy
  • Insect allergy

*Anaphylaxis allergic reactions are serious and often life-threatening. Common anaphylactic allergic reactions are to food, insect stings, medications and latex.


Asthma affects 25 million Americans and 8.4% of our children.  It is a chronic disease that impacts the lungs and can, if untreated, hinder breathing to the point of suffocation. Allergists can help determine what triggers asthma symptoms and attacks, as well as provide methods to control symptoms during physical activity or when in the presence of certain triggers. With the help of a qualified allergist, you can be armed with the education and resources to breathe easier. Common types of asthma include:

Occupational asthma – Caused by fumes, dust or other harmful airborne substances in the work environment.

Childhood asthma – Onset is typically before the age of five.

Primary Immunodeficiency Disease (PIDD)

Individuals with primary immunodeficiency disease (PIDD) suffer from an immune deficiency that results in recurring infections, sometimes severe and difficult to cure. These infections affect multiple parts of the body including the skin, spinal cord, brain and the respiratory system. Common respiratory infections related to PIDD include pneumonia and sinusitis, however several other symptoms may occur.

Typically, PIDD is detected in children, with more serious cases identified in infancy. However, sometimes it takes recurring infections to make a diagnosis, in which case it is generally detected in older children or some adults. Allergists can help diagnose PIDD and provide a plan for treatment.
