About A&ENT Associates

Mission Statement

Adding value to our community as the leaders in allergy, asthma, and sinus care.

Our History

Established in 1957, Allergy & ENT Associates is the largest multi-specialty Allergy, Asthma, and ENT group practice in the Houston area with eighteen locations. We specialize in the diagnosis and treatment of allergy, asthma, and sinus disease.

Our Future

We prioritize multi-specialty collaboration and rely on our team of highly qualified Physicians, well-trained Nurse Practitioners, and Physician Assistants. It’s a group effort here at Allergy & ENT Associates, so you can be sure you’ll find the right healthcare provider for your needs. Our successful practice model has also allowed us to continue to expand nationally.

What can you expect from a visit?

Our patients meet our allergists first who can help determine which kind of treatment is the best course of action. We know that allergies, asthma, and ENT complications are often related, so we make it a priority to collaborate and find a personalized solution for each patient.
