Allergy And Asthma Center, Adults & Children

Really liked Christina ! Listens and does not rush. Great personality and explains everything. Very nice office staff and medical assistants in both the Frisco and McKinney locations.

I had visited here for my kids breathing issues and the same was sorted out in one single visit. The doctors team here are very kind and address ur concern end to end<br>very much satisfied with the outcome

Dr El Hag is a fantastic doctor. He is very thorough, extremely knowledgeable and knows exactly how to treat symptoms. His staff is wonderful as well.

Consistently excellent allergy shots! I’ve struggled with hay fever since I was young, and the treatments here have been life-changing. My symptoms improved within 5–6 weeks and were almost completely gone after about 8–10 weeks of consistent shots. The staff is friendly and crystal clear about guidance for allergy shots and follow-ups

My child is a patient of Dr. El Hag’s and we can’t recommend him enough! My kid was a little bit of a weird case with sinus infections every month/weakened immune system and Dr. El Hag/his staff were the only ones who were able to figure out what was truly going on. He was the only one who was able to treat her effectively and didn’t stop until he found the true cause of what was going on with her. He and his staff are very knowledgeable and always willing to help! We wouldn’t go to anyone else! If you’re looking for an allergist/immunologist - he is your guy!

My family came into the office after my son had a bad allergic reaction and was very worried. We want to give a special thank you to PA Christina for helping us through the entire process and made us feel safe. The whole experience was amazing and very informative! The entire staff was great and although we hope we don't need to come back for another emergency, it's great to know that PA Christina will always be there for us!!

Dr. El-Hag and the entire staff are very knowledgeable and always very helpful when solving my allergy issues. I would highly recommend them.

Dr Elhag allergy treatment was one of the best health decisions I made. I can now walk and enjoy outdoors without the horrible allergy symptoms. It made my life much better. I highly recommend Dr Elhag for life changing allergy treatment.

I have severe atopic dermatitis, lots of food allergies, and I frequently get sinus infections. Their treatment is always efficient and thorough. I've been treated for sinus infections elsewhere and have come back here later when the other treatment hasn't worked. I highly recommend!

Dr. El-Hag is an attentive and caring doctor and he runs his practice to be clean, organized and safe. I have had a few reactions trying to get to the maximum dosage and his care team (nurses & PA) have provided swift, professional and throughout care for me in scary situations. I am not able to achieve the generally recommended max dose, but Dr. El-Hag has worked with me to find a max dose that is right for me. Dr. El-Hag has also referred me to other excellent doctors when my medical needs went beyond the scope of allergies. His team has been diligent to follow up with me as medical issue arise to ensure I do not 'fall through the cracks' and receive the care I need. The nurses all give excellent shots and are vigilant to watch for reactions. Christina, the PA, has an empathetic and gentle demeanor and is excellent in an emergency. I would highly recommend the Allergy & Asthma Center!
