How Allergy Treatment Works
Allergy treatment is a personalized approach that helps identify and reduce the reactions causing your symptoms. Our team works to uncover triggers and create a plan that helps you breathe and feel better.

Testing may include skin testing and RAST (blood) testing to pinpoint the allergens affecting you. Once your triggers are known, treatment can be tailored to your needs.

Common Questions
How do I know what I’m allergic to?
An allergy evaluation usually starts with your symptoms and health history, then may include skin testing or blood testing to help identify specific triggers like pollen, dust mites, mold, pet dander, foods, or other allergens.
What is allergy skin testing?
Skin testing exposes the skin to small amounts of suspected allergens and checks for a reaction. It is commonly used to help confirm what may be causing allergy symptoms
What allergy treatments are available?
Treatment may include medical management, avoidance counseling, environmental control, allergy testing, nasal surgery, and immunotherapy options such as allergy injections or sublingual treatment, depending on your triggers and symptoms.
