We provide expert care for all allergic diseases.

Treatment is customized to the needs of each individual patient. 

Lying in the Grass

Allergic rhinitis, also called hay fever, presents as nasal congestion, runny nose, mucous drainage, sneezing, itchy and watery eyes.   With allergies, your immune system mistakenly identifies a harmless substance, called an allergen, as an intruder.   Environmental allergens include pollen, mold, dust mites, cockroach droppings and pet dander. Irritants such as smoke, strong odors, humidity and weather changes can cause similar symptoms.  Depending on the specific trigger, symptoms can be seasonal or year-round.

Allergic rhinitis is diagnosed based on history, physical examination and allergy skin or blood testing. 
Treatment includes allergen avoidance, medications and/or immunotherapy (allergy shots or drops) based on patient preference.

Sinus headache

Sinusitis is inflammation of the sinuses, air-filled cavities within the face and skull bones.  Sinusitis can present with headache, tooth pain, facial pressure, thick drainage and reduced sense of smell.  It often coincides with nasal symptoms as the two spaces are connected.  Chronic sinusitis may be associated with frequent ear infections, which over time can impair hearing and language development in children.

 Sinusitis may be caused by allergies, infections, air pollution or structural problems in the nose.  Rarely, recurrent sinus infections can indicate an immune deficiency.  Allergic sinus disease can often be treated similarly to allergic rhinitis.  This may include allergen avoidance, medications or immunotherapy


Asthma is a chronic lung disease of airway inflammation and constriction of the airway muscles.  Symptoms include shortness of breath, chest tightness, wheezing and cough. This may cause trouble sleeping or waking at night.  Triggers include allergies, irritant odors, temperature changes, infections and exercise.  Asthma is diagnosed by a thorough history, physical examination and pulmonary function testing in our office.  Treatment includes trigger avoidance, medications, and/or immunotherapy based on testing results.

Patients with severe disease may benefit from biologics, advanced injection therapies offered at ETAA. Treatments offered include Xolair, Fasenra, Nucala and Dupixent. Our specialists will determine if these are right for you.  With proper treatment, patients with asthma enjoy an active lifestyle and participate fully in sports and hobbies.


Many skin conditions have allergic causes including urticaria (hives), angioedema (swelling), atopic dermatitis (eczema) and allergic contact dermatitis (from plants, metals, fragrances, personal care products, etc.)

Each disease state has it's own method of diagnosis and treatment.  Some skin diseases indicate an underlying condition such as cancer or autoimmune disease.   

We proudly offer the advanced treatments Xolair for chronic hives and Dupixent for atopic dermatitis.  These non-steroid injections are very helpful for severe cases.  Our experts will determine if these are right for you.


Food Allergy

Food allergies now affect 1 in 13 children in the US.   Symptoms include itching, rash, hives, swelling, abdominal pain, vomiting, shortness of breath and even low blood pressure and death.  Commonly reported food allergens include peanuts, tree nuts, milk, egg, wheat, soy, fish and shellfish.   However allergies have been reported to hundred of foods.  

Food allergy should be diagnosed only by a board-certified allergy specialist.  This may involve skin testing, blood testing or sometimes an observed food challenge.  The only way to completely prevent a reaction is to avoid the culprit food.  Life-threatening allergies should be distinguished from intolerances, especially in children to prevent unnecessary diet restriction.    


Under an allergist's guidance, early introduction of high-risk foods may prevent the development of allergy in children.  There is currently one FDA-approved product (Palforzia) to reduce the risk of reaction in patients allergic to peanut.  It is only available under an allergist's supervision


Medication allergies range from mild rashes to anaphylaxis.  Certain types of asthma may be triggered by medications.  Commonly seen medication allergies include antibiotics, aspirin and other pain relievers, blood pressure medications, chemotherapy agents, anesthetics and contrast dye. 

 Some medication allergies are outgrown with time while others are unpredictable.  Drug allergy testing determines whether a patient is truly allergic, and drug desensitization administers increasing doses of the drug in order to build temporary tolerance.   


Allergic reactions to insects can range from localized pain and swelling to life-threatening anaphylaxis.  Insects known to cause severe sting reactions include bees. wasps, hornets, yellow jackets and fire ants.    Patients at risk for severe reactions are advised to keep injectable epinephrine nearby.  Venom immunotherapy (allergy shots) protects against reactions and is advised in cases of systemic allergies.


Defects in the body's natural defenses can occur naturally or as a result of some other disease or medical treatment.  This leads to frequent or more severe infections.  Many immune deficiencies affect children and adults.  Certain pediatric diseases are discovered on newborn screening conducted by the state of Texas.  Dr. Chen is a registered Pediatric Immunology Consultant by the Texas Department of State Health Services. 

The most common immune deficiencies present with persistent ear, sinus and lung infections despite appropriate antibiotics.  Specialized tests and medications, such as intravenous immune globulin (IVIG) may be needed to prevent life-threatening illness.
