Our Mission
We provide the complete spectrum of allergy testing at our Sugar Land office — environmental, food, drug, venom, and contact testing — with most results reviewed during the same visit. For patients ready to address the underlying cause of allergic disease, we offer customized allergen immunotherapy, including traditional allergy shots and sublingual options. Immunotherapy is particularly impactful for Sugar Land residents because it can desensitize the immune system to the specific oak, pecan, mountain cedar, Bermuda grass, ragweed, and mold spores that dominate the Fort Bend pollen profile. Many patients tell us their lives change once they no longer have to plan around pollen seasons.
Asthma management is one of our most-requested services in Sugar Land, especially for school-age children and student-athletes in Fort Bend ISD. Houston’s climate — humid, hot, ozone-prone in summer, and cold-dry-windy in winter — is genuinely hard on reactive airways. We use objective in-office testing (spirometry, FeNO, bronchodilator response) to confirm the diagnosis, classify severity, and choose the right controller medication. For patients with severe or biologic-eligible asthma, eosinophilic asthma, nasal polyps, or atopic dermatitis, we provide Dupixent, Xolair, Nucala, Fasenra, and Tezspire infusions and injections on-site.

We've been going here for my kids allergy shots. Great place and staff. The only complaint I have is they have limited open hours during the week.

★★★★★It's a center of great excellence; I'd say it surpasses 5 stars. It's the first time in my 47 years that I've been treated so well, and my health has improved incredibly thanks to Dr. John P. Kelley, M.D. Everyone does a great job, including those who administer the allergy shots—they are kind and extremely professional. Thank you all, congratulations, and blessings.

★★★★★Dr. Chen has been great with our 4-year-old son. His staff is patient, friendly, and made the allergy testing process—never easy for a young child—as smooth as possible. Dr. Chen is knowledgeable, experienced with younger patients, and takes the time to ensure we feel comfortable with the treatment plan. I fully recommend SWAA to anyone seeking allergy care.
