Allergy Testing & Evaluation

Accurate diagnosis is the foundation of effective treatment. We offer comprehensive allergy testing to identify environmental, food, medication, and contact allergies. Testing is tailored to each patient’s history and symptoms to ensure safe, reliable results and a clear path forward.

Environmental & General Allergy Testing

Skin and diagnostic testing to identify triggers such as pollen, dust mites, mold, and pet dander.

Food Allergy Testing

Careful evaluation and testing to confirm or rule out suspected allergies.

Pulmonary Function Testing

Breathing tests that assess lung function and help diagnose asthma or allergy-related respiratory conditions.

Chemical & Drug Patch Testing

Specialized patch testing to identify contact allergies to chemicals, fragrances, and medications.

Targeted therapy for lasting relief

Allergy Treatment Options

Once triggers are identified, we develop a personalized treatment plan focused on symptom control, long-term improvement, and safety. Our approach is structured, medically supervised, and designed to improve quality of life for both children and adults.

Allergy Injections (Immunotherapy)

Allergy shots that gradually reduce sensitivity to environmental allergens over time.

Drug Allergy Management

Evaluation for patients with confirmed or suspected medication allergies.

Penicillin Testing

Accurate testing to determine whether a true penicillin allergy exists, helping avoid unnecessary medication restrictions.

Medicine Challenges

Supervised medication exposure to confirm tolerance or evaluate suspected drug reactions.

Advancing care beyond avoidance

Food Allergy Treatment & Challenges

For many patients, avoidance alone isn’t enough. We provide advanced food allergy services that help clarify diagnoses and, when appropriate, increase tolerance through carefully monitored therapies.

One option we offer is sublingual immunotherapy (SLIT), which places small amounts of allergen under the tongue to retrain the immune system. Because SLIT uses only a fraction of the oral dose, adverse reactions are rare. Treatment involves only 5 office visits spaced 1–2 weeks apart, allowing most patients to reach a maintenance dose in less than two months.

Unlike oral immunotherapy (OIT), SLIT does not require a rest period before or after dosing and allows for flexible time-of-day administration. It is also significantly less expensive than OIT, with most costs billable to insurance. We offer SLIT for milk, egg, wheat, peanut, tree nuts, and sesame.

Oral Immunotherapy (OIT)

A structured, medically supervised treatment that gradually increases tolerance to specific food allergens.

Oral Food Challenges

Closely monitored in-office food exposure used to confirm or rule out food allergies safely.

Sublingual Immunotherapy (SLIT)

A lower-dose, medically supervised therapy that builds food tolerance through daily under-the-tongue drops.

LONG-TERM CARE & PREVENTION

Support at Every Stage of Allergy Care

Allergy and asthma care isn’t just about treating flare-ups, it’s about prevention, long-term management, and adapting care as life changes.

Prevent flare-ups before they start

We help identify triggers and create practical strategies to reduce exposure at home, school, work, and daily life.

Build sustainable management habits

From environmental control to medication guidance and lifestyle adjustments, we focus on realistic plans that support lasting stability.

Care that evolves with you

Whether managing childhood asthma, adult allergies, or immune-related conditions later in life, treatment plans are adjusted as needs change.
