Nearly a Century of Allergy and Asthma Expertise

At North Texas Allergy and Asthma Associates, we have been helping children and adults breathe easier since 1927.

Kind words from our patients

Everyone was very warm & nice. Dr. Kara chef explained my condition in great detail and gave me a regimen to use for my hives.

Kelsey L.

I had a wonderful experience with North Texas Allergy! Dr. Karamched was incredibly helpful, thorough, and made me feel like she was truly invested in my health and well-being. Happy to have found such a wonderful doctor and practice for my allergies and can’t recommend either enough!

Angela H.

Dr Narayan is a consummate professional and her office has provided the best patient experience I have experienced in the history of my allergy care (and do I have a history..). I highly recommend them as they will listen to you and work to develop the best possible plan for your medical care.

Cynthia L.

Dr. Gupta is a superb physician who is so much more than just an allergist. He is aware of and attentive to the interactions that occur between bodily systems. He also takes time to get to know his patients as individuals including, in my case, the multiple family members who are treated by him. I feel exceedingly fortunate to be part of his practice and happily recommend him to anyone who needs an allergist or an expert in the treatment of asthma.
