Our providers treat all allergies and breathing conditions, including food, drug, and pet allergies; nasal congestion and chronic cough; and skin conditions such as hives and eczema. At your appointment, your care team will evaluate you and determine whether care from an otolaryngologist (ENT) or an allergist will lead to the best outcomes for you. Sometimes your condition may require care from both specialties.

Asthma affects millions of Americans and is the most common chronic disease in childhood. Asthma allergies refer to the link between asthma and allergic reactions. Allergens like pollen, dust mites, or pet dander can trigger asthma symptoms, causing airway inflammation and constriction, which results in breathing difficulties and other respiratory issues for individuals with asthma.

Allergies are the result of your immune system’s hypersensitive response to typically harmless substances, known as allergens, like pollen, dust mites, or certain foods. These reactions can lead to a range of symptoms, from sneezing and itching to more severe respiratory or skin issues.

Chronic cough, lasting more than eight weeks, can significantly impact your quality of life and may be caused by allergies, lung conditions like asthma, heartburn, infections, or medications. Our clinical experts will collaborate with you to pinpoint the underlying cause and offer tailored treatments such as allergy interventions, lifestyle adjustments, medications, and asthma management to alleviate your chronic cough and improve your well-being.

Contact dermatitis, a rash caused by skin reactions to substances, can result from allergies or exposure to irritating chemicals. Allergic contact dermatitis arises from an immune system overreaction to allergens, while irritant contact dermatitis occurs when a substance damages your skin’s protective layer. Symptoms may include redness, itching, swelling, and dryness. Treatment options range from steroid creams to oral medications, with allergen identification through allergy testing to help avoid triggers and minimize symptoms.

Eczema, characterized by red, itchy, and inflamed skin, results from an overreactive immune system. While it affects up to 20 percent of children, the majority outgrow it, with only 1-3 percent of adults affected. Symptoms include itching, skin bumps, rash, flaking, and sensitivity. Eczema often has a genetic component and is more common in individuals with other allergies like hay fever and asthma. Effective treatments include allergen avoidance, moisturizing lotions, anti-inflammatory creams, allergen immunotherapy, and newer biologic therapies for non-responsive cases.

Eosinophilic esophagitis (EoE) is a recently identified immune disorder of the esophagus, affecting about one in 2,000 individuals. It leads to swallowing difficulties caused by inflammation in response to triggers like heartburn, food allergies, or seasonal allergies. Symptoms include dysphagia, food regurgitation, irritability in infants, nausea, abdominal or chest pain, and sleep disturbances. Genetic and environmental factors contribute to EoE, with asthma, seasonal allergies, food allergies, and eczema increasing the risk. Common allergenic triggers for EoE include eggs, dairy, wheat, soy, peanuts, nuts, fish, and shellfish, often requiring esophageal tissue biopsy for diagnosis.

Immune deficiencies weaken your body’s resistance to infections, sometimes due to genetic factors or medications like corticosteroids. Symptoms may involve recurrent infections in various body parts, and while lifestyle improvements and vaccines can help, advanced treatments like replacement immunoglobulin therapy provide essential antibodies to fight infections.

Nasal polyps, soft and noncancerous growths in the nasal passages, can lead to chronic congestion, sinus infections, and loss of smell. They are more common in adults and can cause a range of symptoms, including a stuffy nose, headaches, and reduced sense of smell. Medications and surgery are treatment options, with allergy testing to identify potential triggers for these growths.


Nasal congestion, a common issue for many, occurs when the membranes in the nasal passages become swollen and produce excess mucus in response to irritants. These irritants can be allergens, non-allergic factors like pollution or smoke, infections, or changes in environmental conditions. Our allergy testing and specialists can help pinpoint the cause and provide tailored solutions to manage nasal congestion.

Peanut desensitization, or desensitization therapy for peanut allergies, is a treatment method that gradually exposes individuals to increasing amounts of peanut protein under controlled conditions. This approach aims to reduce or eliminate the severity of allergic reactions to peanuts by helping the immune system become more tolerant to this allergen over time. It can be particularly beneficial for those with peanut allergies, offering a path toward greater safety and peace of mind in managing their condition.


Relief treatment plans are individualized for each patient. At the Relief Allergy & Sinus Institute, we employ a first-of-its kind  multidisciplinary approach to  your care which includes experts in allergic diseases, nasal and sinus conditions, immunologic disorders and asthma so you can be sure you are receiving the latest most advanced care. These experts will work together to develop a personalized treatment plan for your specific condition  with the  goal of rapid relief for your symptoms and improve your quality of life.

Peanut allergies affect approximately 1 million children in the United States, with only one in five eventually outgrowing them. They are the leading cause of life-threatening food allergic reactions in the country. Desensitization involves gradually exposing you (or your child) to increasing amounts of peanuts to reduce the overreactive immune response, preventing severe allergic reactions.

Allergy shots, or allergen immunotherapy, are a preventive treatment for allergies. By gradually exposing you to allergens through small injections, we aim to reduce or eliminate your allergic symptoms by desensitizing your overreactive immune response, addressing the root cause of your allergies.

Cluster immunotherapy is an accelerated desensitization method utilizing allergy shots in clusters, often just one or two days a week, to reach a maintenance dose more rapidly than traditional immunotherapy, effectively reducing or eliminating allergic symptoms.

Some of the most common offenders in drug allergies include aspirin and non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen/Advil and naproxen/Aleve. Others are antibiotics such as penicillin, x-ray dyes and some chemotherapy drugs. Even your herbal supplements may be allergy culprits.

Our patch testing technique is designed for diagnosing allergic contact dermatitis, a skin condition triggered by allergens. This method is needle-free and involves applying patches with suspected allergens to your back for a couple of days. After removal, our allergy provider evaluates your skin’s reactions, which can range from mild redness to more severe allergic responses like itching. This process allows us to pinpoint the specific substances causing your skin discomfort and tailor your treatment accordingly.

Immunodeficiency disorders, such as IgG deficiency, weaken your immune system and make you susceptible to recurrent or persistent infections that are challenging to treat. Immunoglobulin replacement therapy, administered intravenously or subcutaneously, is an effective approach to boost IgG levels and enhance your immune response, helping combat these infections and improve your overall health.

Venom immunotherapy, or insect allergy shots, are a preventative treatment for allergic reactions. These injections may greatly reduce or even put an end to your allergy symptoms. Other drugs like antihistamines treat your symptoms whereas venom immunotherapy treats the cause of your insect allergy symptoms.
