What Our Patients Say About Us
Dr. Foster and staff are very caring and friendly. With immunotherapy, I have gone from needing an asthma inhaler daily to almost never having asthmatic symptoms. You won't find a better doctor to treat allergy and asthma issues.

Great office!! I visited the South location, on Colorado. Everyone from the front office staff to Dr. Foster (Roshni) were very friendly and professional. I was a new patient, but they worked me in when they realized how badly I felt. Cannot tell you how grateful I am for how much they helped me get over quite a nasty sinus infection this week!!
Ellen D.
I have enjoyed visiting husband and wife team, Drs. Foster. The office staff is friendly and helpful. My allergy needs were well addressed in a thorough manner and my son's potential peanut allergy testing and challenge all went smoothly. I appreciate the charity work they do as well. They are very blessed and pass the compassionate care to us.

Dr. Roshni Foster and her staff are caring, helpful and highly knowledgeable about my allergy issues. North Texas Allergy quickly identified my allergies and successfully managed them through the doctor's maintenance program. Since getting care from Dr. Foster, I have not encountered allergy-based colds that I normally suffer from several times a year. I cannot say enough how much they have helped me. I highly recommend them to anyone in the north Texas area suffering from allergies. Thanks so much Dr. Foster and staff!!!
Stephen R.
I am so grateful for this team. The staff is just over-the-top kind and helpful. They are really considerate of my time and needs, and always go out of their way to help me with insurance and saving money. Both Drs. Foster really take the time to listen and they make it clear that their goal is to improve my quality of life, not just get me out the door. They have greatly improved my health and my son's health. I can't recommend them enough!
