Food Allergy Center
Oral immunotherapy that builds tolerance one small dose at a time
Our Food Allergy Center, led by pediatric allergist Dr. Ingrid Lindqvist, treats food allergy with oral immunotherapy (OIT). Your child eats a carefully measured, slowly increasing amount of the food every day, with each step up done in our clinic. The goal is protection from accidental bites, and for some families, much more.

- Tree nuts

- Egg

Allergy and asthma care in Arlington, Keller and Mansfield
Treatment that looks for the cause, not just the next refill
Antihistamines and inhalers have their place. But if you have been taking them every spring and fall for years, it is worth knowing what you actually react to. At Aller-Vista, our board-certified allergists test first, explain what the results mean for your family, and build a plan that can reduce how much medicine you need over time.
- Seasonal and indoor allergies
- Asthma and chronic cough
- Eczema, hives and contact rashes
- Food allergies, including OIT
Our team speaks your language. Many of our providers and front desk staff are bilingual, so you can talk through symptoms and results in the language you are most comfortable with.
What brings you in?
These are the conditions we treat most often. Each page explains symptoms, testing and treatment options in plain language.
Allergies
If your nose runs from cedar season into spring and your eyes itch every fall, we find out which pollens, molds or indoor allergens are behind it and build a plan around your results.
About allergiesAsthma
If you reach for your rescue inhaler more than you’d like, or your child coughs through the night, we measure your lungs, find your triggers and give you a written plan you can follow.
About asthmaEczema
If your skin cracks, itches and flares no matter which lotion you try, we look for allergic and everyday triggers, build a skin care routine that fits your family and discuss advanced options when needed.
About eczemaSinusitis
If you’ve had round after round of antibiotics or your sinuses never fully clear, we look for allergies, nasal polyps and immune problems that keep the cycle going, then plan the next steps with you.
About sinusitisChronic cough
If you’ve been coughing for months and cough drops, antibiotics or a chest X-ray haven’t given you an answer, we test for asthma, allergies and other common causes, one step at a time.
About chronic coughFood allergies
If every birthday party, school lunch or restaurant meal comes with worry, we confirm which foods are truly a problem, teach your family to handle reactions and discuss whether oral immunotherapy fits.
About food allergiesTesting and treatment
Accurate testing first. Then immunotherapy that can calm your immune system’s response over time, with medicines to control symptoms along the way.

Allergy testing
Skin prick, blood, patch and breathing tests that show what is behind your sneezing, rash, cough or food reactions. Skin test results are ready in about 15 to 20 minutes.

Allergy shots
A custom mix of the allergens you react to, given as regular injections that build tolerance over time. Walk in during shot hours at any of our three DFW clinics, no appointment needed.

Sublingual drops
Needle-free immunotherapy you take at home. A few drops under the tongue each day build tolerance to pollen, dust mites and pets, with far fewer trips to the clinic.

Oral immunotherapy
Tiny, carefully increasing daily doses of a food allergen that raise the amount it takes to cause a reaction. Our Food Allergy Center offers OIT for peanut, tree nuts, milk, egg, wheat and sesame.
What’s in the air around Dallas–Fort Worth
North Texas has a pollen season almost every month of the year. If your symptoms follow the calendar, testing can tell us which of these is behind them.
| Allergen | Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|---|

Mountain cedar pollen blows north from the Hill Country in December and January and hits even people who never had allergies before.
Trees and grasses overlap from March to May, which is why spring is the hardest stretch for many patients.
Immunotherapy takes months to build up. Starting in summer means you are better protected by ragweed and cedar season.

Meet your allergy team
Three board-certified allergists and two advanced practice providers, across three clinics. Spanish and Arabic spoken.

Dr. Nabil Saadeh, MD
Founder and medical director
Dr. Saadeh opened the first Aller-Vista clinic in Arlington in 2014 after years of watching patients cycle through urgent care for the same spring symptoms. He believes most people with allergies deserve a clear answer about what they react to and a plan that goes beyond the next refill.
- Focus
- Adult and pediatric allergy, allergy shots, hives and drug allergy
- Sees patients in
- Arlington, Keller
- Languages
- English, Arabic

Dr. Ingrid Lindqvist, MD
Pediatric allergist, director of the Food Allergy Center
Dr. Lindqvist trained in pediatrics before specializing in allergy and immunology, and food allergy has been the center of her work ever since. She built the Aller-Vista Food Allergy Center around one idea: families should understand every step of oral immunotherapy before they start it.
- Focus
- Food allergy and oral immunotherapy, oral food challenges, infant eczema and early allergen introduction
- Sees patients in
- Arlington, Mansfield
- Languages
- English

Dr. Adaeze Nwosu, DO
Allergist and immunologist
Dr. Nwosu leads asthma and eczema care across Aller-Vista. She is often the person patients see when inhalers and creams have stopped being enough and it is time to look at the full picture, including breathing tests, triggers at home and whether a biologic medicine makes sense.
- Focus
- Severe and difficult asthma, atopic dermatitis (eczema), biologic therapy
- Sees patients in
- Keller, Mansfield
- Languages
- English

Tomás Arriaga, PA-C
Physician assistant
Tomás has worked in allergy and immunology since 2017. He performs skin testing, sees follow-up patients on allergy shots and drops, and manages many of our sinus and chronic cough patients alongside our physicians.
- Focus
- Allergy testing, sinus and chronic cough, shot and drop follow-ups
- Sees patients in
- Arlington, Mansfield

Lucía Paredes, FNP-C
Family nurse practitioner
Lucía spent eight years in pediatric primary care before joining Aller-Vista, and she still thinks like a family practice clinician: what will this plan look like at 7 a.m. on a school day? She sees children and adults for follow-up visits at our Keller clinic.
- Focus
- Pediatric allergy follow-ups, asthma action plans, epinephrine and inhaler teaching

What patients tell us
A few words from families we care for in Arlington, Keller and Mansfield. Shared with permission.
Our son started peanut OIT with Dr. Lindqvist last year. Every up-dose day the nurses explained exactly what to watch for, and we always had a number to call after hours. He just passed his maintenance challenge and we cried in the parking lot.
Tomás did my testing and walked me through the results in Spanish so my mom could follow along. Two years into shots and I made it through cedar season without living on antihistamines.
Dr. Saadeh listened to the whole story instead of handing me another inhaler. The breathing test explained a lot. Being able to talk through things in Arabic with the front desk made my parents comfortable too.
Our daughter’s eczema had been bad since she was a baby. Dr. Nwosu found a contact allergy nobody had tested for and gave us a plan we could actually follow. Her skin has not looked this good in years.
I travel for work and could never keep up with shots. Drops fit my schedule. The team was upfront about the cost and what insurance would and wouldn’t pay before I started.
I had coughed for most of a year. Lucía and Dr. Nwosu worked out it was a mix of postnasal drip and asthma. Three months later I can get through a church service without leaving the room.
