Dr. Mary D. Blomquist


Mary D. Blomquist, M.D.
Mary D. Blomquist, M.D., has been in practice since 1990 and specializes in pediatric and adult asthma, allergy and immunology and has expertise in the diagnosis and treatment of adult and pediatric asthma, respiratory, food, insect and drug allergies, chronic rhinosinusitis and immunodeficiency syndromes.

“I was intrigued by the immune system because it can affect every system in the body. If it is overactive, the patient will have allergies or autoimmune disease. If it is deficient, the patient is at risk for infections. During my Allergy and Immunology fellowship at Texas Children's Hospital, I cared for children with allergies and asthma as well as some with severe combined immunodeficiency. With their demonstrated willingness to tackle difficult problems, it was an excellent place to gain experience from a wide variety of patients.

Later, I personally experienced the challenge of raising my own child with asthma, allergic rhinitis, and food allergy. My daughter now handles all aspects of her peanut allergy successfully. Living with these conditions gives me a better understanding of my patients and their families’ struggles.

As allergists, we can have a significant impact on a patient’s quality of life. Southwest Allergy & Asthma Center combines our superb team of specialists with leading-edge treatments to give our patients optimal results in their health.
