Allergy & Immunology

Our specialists treat conditions like acute and chronic sinusitis, nasal polyps, allergic rhinitis, and environmental allergies that cause congestion, facial pressure, and sneezing. We also manage eye allergies, hay fever, and allergic bronchopulmonary aspergillosis (ABPA) in patients with asthma or cystic fibrosis. Personalized testing and treatment plans help you breathe easier year-round. 

We provide care for allergic skin conditions such as eczema, contact dermatitis, persistent hives, angioedema, and hereditary angioedema. Our team identifies triggers, relieves itching, and prevents flare-ups with tailored treatments and education. Ongoing management helps restore comfort and protect skin health. 

Our clinic diagnoses and treats all types of allergies, including food, drug, insect, animal, and pollen allergies. We create individualized care plans to manage reactions and prevent emergencies. For severe allergies, we provide anaphylaxis management and education on epinephrine (EpiPen®) use for rapid response. 

We evaluate and manage immune-related conditions such as eosinophilic disorders, primary immune deficiencies, and acquired immunodeficiency syndromes. Both children and adults benefit from early diagnosis, infection prevention, and targeted therapy. Our goal is to strengthen immune function and improve long-term health outcomes. 

We offer multiple testing options to identify allergic triggers, including skin testing, patch testing, blood testing, and drug allergy testing. These tests help detect sensitivities to environmental allergens, foods, medications, and insect stings. Accurate diagnosis allows for safer, more effective treatment planning. 

Our testing services identify reactions to pollen, dust mites, pet dander, mold, and common food allergens like nuts, eggs, dairy, and shellfish. This helps guide dietary changes, avoidance strategies, and immunotherapy options. Testing is quick, safe, and tailored to your allergy history. 

We provide allergy shots and oral immunotherapy to gradually reduce sensitivity to environmental and food allergens. These long-term treatments retrain the immune system to react less strongly over time. Patients often experience fewer symptoms and a reduced need for medication. 

Under medical supervision, oral food challenges and drug challenges (e.g., penicillin) safely confirm or rule out allergies. These procedures are performed in controlled settings to ensure patient safety. Confirming tolerance allows for broader treatment options and peace of mind. 

We design personalized plans for managing seasonal and year-round allergies, combining avoidance strategies, medications, and immunotherapy. Our approach helps minimize flare-ups caused by pollen, mold, or indoor irritants, so you can enjoy relief every season. 

We offer desensitization therapy for allergies to bee, wasp, or fire ant stings, significantly reducing the risk of severe reactions. Education and emergency preparedness, including EpiPen® use training, are part of every care plan for added safety. 

Our ongoing care programs help patients manage chronic allergies and prevent life-threatening reactions. This includes emergency action plans, periodic testing, and treatment adjustments as needs evolve. We focus on empowering patients with tools to live safely and confidently.

Allergic reactions can manifest in various ways, but common symptoms include sneezing, itching, watery eyes, nasal congestion, and skin rashes. If you frequently experience these symptoms, it's advisable to consult with an allergy specialist for accurate diagnosis and tailored treatment options. 

You should consider seeing a specialist if you experience: 

• Persistent or seasonal allergy symptoms 
• Recurrent infections 
• Unexplained rashes or swelling 
• Food or drug reactions 
• Difficulty breathing due to asthma or allergies 

Distinguishing between allergies and respiratory infections can be challenging due to overlapping symptoms. Allergies are typically chronic or seasonal and occur without fever, while infections come on suddenly, often with fever, body aches, or fatigue. Our specialists use clinical evaluations and allergy testing to determine the root cause of your symptoms. 

Symptoms of a food allergy can range from mild reactions such as itching, swelling, or hives to severe reactions like shortness of breath or anaphylaxis. If you notice symptoms after eating certain foods, schedule a visit with our allergy team for testing and personalized management. 

The eight most common food allergens are peanuts, tree nuts, milk, eggs, soy, wheat, fish, sesame, and shellfish. However, reactions can occur from a wide range of foods. We offer comprehensive food allergy testing to help identify your specific triggers. 

Yes, it's possible to develop new allergies as an adult, even if you've never had symptoms before. Factors like environmental changes, hormonal shifts, and genetic predisposition can trigger adult-onset allergies. Our specialists can help identify the cause and recommend effective treatments. 

Absolutely. Allergy testing is safe and well-tolerated for children, including infants and toddlers. We use age-appropriate methods like skin prick testing or blood tests to identify triggers and create customized treatment plans for children with food allergies, eczema, or environmental triggers.

Yes, allergy shots (immunotherapy) are one of the most effective treatments for reducing allergic symptoms over time. They work by gradually desensitizing your immune system to specific allergens, such as pollen, dust mites, or pet dander, and can offer long-lasting symptom relief even after treatment ends. 

Both allergy shots and allergy drops are forms of allergen immunotherapy designed to reduce allergic reactions. They differ in how they’re administered and what they're approved for: 

• Allergy Shots (Subcutaneous Immunotherapy - SCIT): 
• Administered by injection in a medical office 
• Typically given weekly, then monthly over 3–5 years 
• FDA-approved in the U.S. for environmental allergies (e.g., pollen, dust mites, pet dander) 
• Allergy Drops (Sublingual Immunotherapy - SLIT): 
• Placed under the tongue and can be taken at home 
• Taken daily and typically continued for 3+ years 
• Not FDA-approved for all allergens in the U.S., but commonly used for grass, ragweed, dust mites, and some food allergies 

Which is right for you? It depends on your allergy type, lifestyle, and treatment goals. Our allergy specialists can help you decide which option offers the best balance of safety, convenience, and effectiveness for your needs. 

An allergist/immunologist is a physician who specializes in diagnosing and treating allergic conditions and immune system disorders, including primary immunodeficiencies. These specialists help manage chronic infections, anaphylaxis, asthma, eczema, and immune-related conditions that impact quality of life.

Immunological disorders include conditions where the immune system is either overactive or underactive. Examples include: 

• Primary immunodeficiencies (e.g., CVID)
• Recurrent or chronic infections due to immune dysfunction
• Severe allergic conditions (e.g., anaphylaxis, food allergy, asthma, eczema)
• Mast cell disorders or other immune dysregulation syndromes

Our clinic provides specialized care and long-term management plans for these conditions.
