CHRISTOPHER COLLACO, MD, PH.D - ADVANCED ALLERGY AND ASTHMA CENTER REVIEWS
Dr. Collaco is a terrific allergist and thorough doctor who takes excellent care of his patients. I went to ER and they just gave me Cortisone shot , a week later went to my PCP she also gave me a Cortisone shot. I walked into Dr. Collaco and he took his time evaluating me seeing what medicines would work the best. Genuinely cares for his patients. I will be back to get allergies under control after I get better. I highly recommend this doctor if you suffer from allergies , he has been my doctor for 7 years.
Our family has been going to Dr. Collaco for years. He and his entire staff are great and always treat us like family. Dr. Collaco takes time to explain in great detail any treatment plan and answer any questions we may have. Highly recommend the Advanced Allergy and Asthma Center.
Dr. Collaco is a great allergist. I suffered from allergies for several years and when I found Dr.Collaco I was miserable. He was great! Took great care of me and I started taking allergies shots. It was a life changing. Very happy with his clinic.

DOANH NGUYEN, MD, FAAAAI - TEXAS ALLERGY, ASTHMA & SINUS REVIEWS
I love it here! Dr. Nguyen is always on time and he is so patient and accommodating. I’ve been going to this office for over a year and I’ve never had a complaint. The shots have been very effective and I can finally enjoy being outdoors again. He has fixed my allergies and I couldn’t be more grateful!
This allergist has been me and my brother’s doctor for a couple years now. We come routinely for allergy shots and have been both been feeling so much better. The trick is staying on top of your shots and then you start to really feel the difference. The doctor is patient and understanding when we have questions about our treatment. We would highly recommend. Two thumbs up!
Great service, great Doctors and staffs..highly recommended.
