The curious: Who is an Allergist?.

Allergists are sometimes called “allergy doctors”.
An allergist is a physician trained to treat many types of allergic disorders, asthma, and other immunologic disorders. The most common allergic diseases treated by an allergist include allergic rhinitis or hay fever, sinusitis, non-allergic rhinitis, nasal allergies, skin allergies including hives and eczema, and both allergic and non-allergic asthma.
Allergists are also experts in the diagnosis and treatment of food allergies, stinging insect allergies, drug allergies, and a variety of allergy related issues.
Allergy doctors are highly trained. Formal training to become an allergist takes a minimum of nine years after college. After four years in medical school, one then does an internship and residency in either pediatrics or internal medicine, a process lasting 3-4 years. In order to become an allergist, one would then do a fellowship lasting 2-3 years in an approved allergy training program. An allergist would then take an exam in order to receive board certification. Board certification indicates that the allergist has reached a high level of expertise and is recognized by the public and the medical community as an expert in his or her field of medicine. Many allergists are double boarded, meaning that they have board certification in two areas, Allergy, Asthma, and Clinical Immunology, as well as either Pediatrics or Internal Medicine.

In summary, An Allergist is a medical practitional or specialist who is dedicated to treating all Allergy cases.
