What Texas Allergy Group does

Texas Allergy Group PLLC is a physician-owned allergy, asthma, sinus, and immunology practice headquartered in Houston, Texas, operating six office locations across the Greater Houston metropolitan area including Katy, Cypress, Southwest Houston (Chinatown), Northwest Houston (Red Oak), Memorial City, and the Medical Center. The practice is staffed by three board-certified allergists and immunologists (Doanh Nguyen, MD FAAAAI; Aneesh Angirekula, MD; Chen Lin, MD) and two nurse practitioners (Sandy Gonzalez, NP; Jenny Pham, NP). It delivers care to adult and pediatric patients with allergic rhinitis, asthma, sinusitis, food allergies, eczema, chronic urticaria, drug allergies, insect sting allergies, mast cell activation syndrome (MCAS), primary immunodeficiency, and related inflammatory conditions, with multilingual support in Vietnamese, Korean, and Spanish.

The practice organizes its clinical offering around four dedicated specialty clinics — Food Allergy Clinic, Allergic Inflammation Clinic, Eczema Clinic, and Chronic Urticaria Clinic — supported by a comprehensive diagnostic and treatment menu. Diagnostics include skin prick and intradermal testing, patch testing, spirometry, FeNO measurement, oral food and drug challenges, penicillin and local anesthetic allergy testing, and sinus CT imaging. Treatments span allergen-specific immunotherapy (subcutaneous shots and sublingual drops/tablets), food and drug desensitization (OIT/SLIT), aspirin and insect venom desensitization, biologics monoclonal antibodies (Nucala, CinQair, Xolair, Fasenra), and immunoglobulin replacement therapy. The practice also operates a Clinical Research Unit in collaboration with the Institute for Allergic Inflammation and offers Long COVID and MCAS management services.

Texas Allergy Group generates revenue through professional services billed to patients and insurance carriers, including consultations, diagnostic procedures, immunotherapy administration cycles (3-5 year maintenance), and high-value biologics infusions. The practice functions as a direct-to-consumer healthcare provider, accepting a wide range of insurance plans and offering CareCredit financing for out-of-pocket expenses. Appointments are scheduled online via the Wiki Allergies platform or by phone, with same-day visits available at select locations and no appointment required for allergy injections. The practice maintains an active Facebook presence and a comprehensive content-marketing website for patient acquisition in the Houston metro market.
