New York City's Top Rated Allergists

NY Allergy & Sinus Centers is an allergy, asthma, sinus and immunology practice with nine offices across Manhattan, Queens, Staten Island and Long Island. We have been treating New Yorkers for more than 30 years.

NYASC Allergists

Most patients complete testing and get a diagnosis in a single visit, and in many cases we can start treatment the same day. We see adults and children, we take referrals for complex cases, and we accept most major insurance plans.

What we treat

Allergy is not one condition, and the reason people end up seeing us varies a great deal.

Food Allergies

Peanut, tree nut, milk, egg, wheat, soy, sesame, fish and shellfish, plus the less common ones people struggle to get answers on. Our A to Z allergy library covers well over a hundred individual foods and triggers. Start with food allergies if you are not sure where your reaction fits.

Environmental and seasonal allergies

Tree, grass and weed pollen, dust mite, mold, cockroach and pet dander. New York has a long pollen calendar and a housing stock that keeps indoor allergens in play year round, so a lot of people here are reacting to more than one thing at once.

Skin conditions

Eczema, hives, contact dermatitis and reactions to metals, fragrance and preservatives.

Drug Allergies

Penicillin, NSAIDs, anesthetics and chemotherapy agents. Most people who carry a penicillin allergy label do not have one, and testing to remove that label changes what antibiotics are available to you for the rest of your life.

Asthma and respiratory conditions

Asthma, chronic cough, rhinitis and hay fever.

Sinus and nasal conditions

Sinusitis, nasal polyps and non-allergic rhinitis. We offer minimally invasive sinus treatment, nonsurgical sinus care and 3D sinus imaging in the office, so a chronic sinus problem gets worked up in one place rather than bounced between an allergist and an ENT. More on nose and sinus health.

Sleep Apnea

Sleep apnea sits in this practice for a reason. Persistent nasal congestion forces mouth breathing, and mouth breathing makes obstructive sleep apnea more likely and more severe. If your congestion is allergic, treating the allergy is part of treating the apnea, and that connection gets missed when the two are handled by separate practices.

We can arrange a sleep study, and for patients who cannot tolerate CPAP or would rather not use it, we fit custom oral sleep appliances that hold the jaw forward to keep the airway open.

We also see and treat anaphylaxis, and part of every food and venom allergy consultation is making sure you leave knowing what to do in the first minute of a reaction.

Testing and diagnosis

Guessing at a trigger by elimination alone tends to waste months. We test. More detail on all of it is on our allergy testing page.

Skin Prick Testing gives results in about twenty minutes and is the starting point for most environmental and food allergy work.

Blood Testing measures specific IgE and is useful when skin testing is not an option, such as when a patient cannot come off antihistamines or has widespread eczema.

Patch Testing identifies delayed contact reactions to metals, fragrances, preservatives and adhesives. Results are read over several days rather than the same visit

Intradermal Testing is more sensitive than skin prick and is used for venom and drug allergy work.

Oral food and drug challenges are the definitive test. Supervised, in the office, with the equipment and staff to manage a reaction. This is how a suspected allergy gets confirmed or ruled out for good.

Elimination Testing has a place, usually alongside other testing rather than instead of it.

Treatment

Testing tells you what you are reacting to. Treatment is the part that changes your life, and it is where practices differ most.

Allergy shots

Subcutaneous immunotherapy is the only treatment that changes the underlying allergy rather than managing the symptoms. It takes three to five years and the protection lasts well beyond that.

Sublingual immunotherapy is an alternative for patients who cannot commit to regular in-office injections.

We offer OIT for peanut and other food allergies. The goal is not a cure. It is raising the amount you can tolerate to the point where an accidental exposure stops being an emergency.

Palforzia, the first and only FDA approved oral immunotherapy product, was withdrawn from the market on 31 July 2026. That does not change what is available to patients here. Peanut OIT continues, and it did before Palforzia existed.

OIT is done under medical supervision, in the office, with observation after each dose increase. Never at home and never on your own.

Dr. Lin performs aspirin desensitization for patients with aspirin-exacerbated respiratory disease, which is often the missing piece for people with nasal polyps that keep coming back after surgery. Some cases are done in the office and some in a hospital setting. Your allergist will decide which is appropriate.

For severe asthma, chronic hives and eczema that has not responded to standard treatment, we prescribe and manage biologic therapy through a concierge program, so the paperwork, prior authorisation and scheduling are handled here rather than left with you.

We take part in clinical trials, including trials of Dupixent. Patients who are interested can ask about current enrollment, and you can read more on our clinical trials page.

Patients at risk of anaphylaxis leave with a prescription for epinephrine and a plan for using it. Options are EpiPen, Auvi-Q and neffy intranasal epinephrine, and which one suits you depends on age, weight and whether needles are a barrier. The FDA removed the lower age limit on neffy in 2026, so it is now an option for younger children too, which matters for families where a needle is the reason a device gets left at home. Our comparison of the three goes through the differences.

Antihistamines have a role after epinephrine has been given, to help with the histamine-driven part of a reaction. They are not a substitute for epinephrine and they are not what you carry for a food or venom allergy.

Where our providers have particular depth

Everyone here sees the full range of allergic conditions, and who you see depends on which office suits you and when you can get in. That said, some have gone deeper in particular areas, and if you already know roughly what you are dealing with, it may be useful to know

Children

Dr. Nejat is board certified with the American Board of Pediatrics and has spent 30 years treating children and adults side by side.

Food allergy and oral immunotherapy

Dr. Rashtian’s research background is in peanut and tree nut allergy. Toni Santiago, PA-C works extensively in food allergy and oral immunotherapy.

Drug allergy, including penicillin

Dr. Lin takes referrals for drug allergy and is board certified with the American Board of Allergy and Immunology. Dr. Patel also works closely in this area.

Research and publications

Our physicians publish. That matters less for bragging rights than for what it means day to day: the people treating you are reading the literature and contributing to it. Dr. Lin has published on dupilumab-associated limbic keratoconjunctivitis in The Journal of Allergy and Clinical Immunology: In Practice, on mepolizumab in eosinophilic pneumonia in The Journal of Asthma, and has contributed chapters to Stiehm’s Immune Deficiencies and Integrative Medicine: Principles for Practice. He is also a co-author on a 2026 case report in Clinical Case Reports describing systemic hypersensitivity to tirzepatide but not semaglutide, and on the abstract behind it in Annals of Allergy, Asthma & Immunology. That GLP-1 work came out of what we were seeing in the office. Patients on semaglutide and tirzepatide were presenting with reactions nobody had characterized yet, so it got written up. Dr. Rashtian has published on asthma in The Journal of Asthma, and Dr. Nejat’s earlier work appears in Pediatric Allergy and Immunology and the American Journal of Respiratory and Critical Care Medicine. Individual publication lists are on each provider’s profile.

How to choose an allergist in New York

Check the board certification. Allergy and immunology is a subspecialty. A physician gets there through a residency in internal medicine or pediatrics and then a two or three year fellowship. You can verify any physician’s certification free at certificationmatters.org. Do not rely on a directory profile, which is often auto-generated and frequently wrong.

An allergist is not the same as an ENT. If your problem is structural, an ENT is the right call. If your symptoms are driven by an immune response, an allergist is. Chronic sinus problems are often both at once, which is why a practice that does allergy testing and sinus imaging in one place saves you a round trip.

Ask what happens in the first visit. Some practices test on the first visit and some book you back. If you are taking time off work, that is worth knowing before you go.

Ask what treatments are done in-house. Oral immunotherapy, aspirin desensitization, drug challenges and biologics all require staff, time and equipment to run safely. Plenty of practices will diagnose you and refer the treatment elsewhere. There is nothing wrong with that, but you should know before you start.

Come off antihistamines first, if you can. Most skin testing needs you off them for around five to seven days. Call ahead and ask, because turning up medicated usually means rebooking.

Bring the specifics. What you ate or were exposed to, how long until symptoms started, how long they lasted, what you took, and whether it has happened more than once. Photographs of a rash are genuinely useful. The history does more diagnostic work than any single test.

Second opinions are normal. If you have been told to avoid a long list of foods on the basis of a blood panel alone, that is worth a second look. Sensitization on a blood test is not the same as a clinical allergy, and unnecessary avoidance carries its own costs.
