Welcome to Our Practice


At Texas Regional Asthma and Allergy Center, our priority is to deliver quality care to informed patients in a comfortable and convenient setting.

Quality Care

When you have healthcare needs, you need to turn to a doctor who listens and responds ... an experienced professional who knows the field and can effectively diagnose and treat your needs ... a friendly staff who counsels you on the best ways to maintain and improve your health. Our Southlake practice meets all these criteria. Plus, you benefit from a dedicated team of trained professionals who give you the individualized attention you deserve.

Informed Patients

The allergists at Texas Regional Asthma and Allergy Center believes that informed patients are better prepared to make decisions regarding their health and well being for allergies, allergy treatment, and asthma. For this reason, we’ve included all of the important details about our services and procedures on this website.

Comfortable, Convenient Setting

The best care in the world doesn’t mean anything if you can’t access it. At Texas Regional Asthma and Allergy Center, we strive to make our Southlake office as efficient and convenient as possible. Included in these web pages is information about Texas Regional Asthma and Allergy Center’s office, including our Southlake location, maps, directions, hours, insurance and appointment scheduling.
