An allergy is an abnormal sensitivity or exaggerated reaction of the immune system to a substance, which, in the majority of people causes no symptoms at all. 
Our allergists will conduct a patient history including an assessment of your symptoms, a relevant physical exam, and a thorough environmental evaluation.

Asthma is a chronic lung disease that inflames and narrows the airways. It has no known cure, but by identifying triggers and developing a proper management plan, asthmatics can lead a healthy, active life.
Controlling allergies is the first step to controlling asthma. In addition, there are two types of medicine for the treatment of asthma.

Food Allergies

A food allergy results when the immune system mistakenly targets a harmless food protein – an allergen – as a threat and attacks it. 
The most important treatment for food allergies is a proper diagnosis and strict avoidance of the food allergen to prevent an allergic reaction. Currently, there is no cure for food allergies.

Immune Deficiency

If you are experiencing recurring infections, it could be the result of primary immunodeficiency disease (PIDD). 
When part of the immune system is either absent or not functioning properly, due to hereditary or genetic reasons, it’s called PIDD.

Sinusitis is an inflammation of the sinuses, the hollow cavities within the cheekbones, around your eyes and behind your nose.
Your allergist will conduct a medical history, including an assessment of your symptoms and a relevant physical exam to look for polyps or changes in the anatomy of the nose (if necessary, a CT scan will be ordered).

Insect Sting Allergies

Most everyone will react in some way to stinging insects, but up to 13.5 million people in the U.S. may be at risk of anaphylaxis, a life threatening allergic reaction.
If you have experienced an allergic reaction of any kind, consult a board certified allergist as soon as possible.

Skin Allergies

Although allergic skin reactions are very common, it is often difficult to determine what causes them. Irritated skin can be caused by a variety of factors. 
These include immune system disorders, medications and infections. When an allergen is responsible for triggering an immune system response, then it is an allergic skin condition.

Drug Allergies

Adverse reactions to medications are common, and can cause a range of symptoms, which can include skin rashes and hives, itching, swelling, respiratory problems, and anaphylaxis. 
In many cases, we are able to test for specific drug allergies. Please contact our office for specific drug allergy testing questions.

Lung Conditions

We treat certain lung conditions, especially those related to asthma and allergy.
Our allergists are different from pulmonologists, who generally focus on treatment of more serious lung diseases that require hospital treatment.

Pollen Count Information

A Pollen count is the measurement of the number of grains of pollen in a cubic meter of air. The higher the number, the more people will suffer if they are allergic to a particular pollen.
