Testimonials Of Patients

At Family Allergy and Asthma Care, it is our mission to enhance the health and well being of our patients and their families

Karen G.

Flower Mound, Texas
I see Dr. Marie Fitzgerald at this clinic. She's very thorough and takes the time to explain things to you if you ask her more in depth questions. I like that she really tries to understand what's going on with you versus just prescribing you a pill and shuttling you out the door. She also teaches at UT Southwestern, which is a nice credential to have.

Mitch M.

Carrollton, Texas
The nursing staff is well professional and well spoken. ANY and ALL questions I have EVER had have been answered in a timely manner. I have had shots on a regular basis here and it's been a good experience there too. With the wifi available you can get work done while you wait to get the all clear to leave.

Derek S.

McKinney, Texas
I have been a patient of this clinic for 8 years now. It has truly been a life saver. I say that because I had a near death reaction and I was literally saved walking in the door by the most responsive care you could get anywhere. I can say that all the Doctors here are the most professional, the most educated and the most competent of any in the industry.

Mark S.

Denton, Texas
The office is neat and clean and the building is easy to find and get in and out of. I hope that if you are looking for a family allergist you would at least consider going to Family Allergy in Flower Mound. I would recommend this place to any friend or family member.


Successful patient care begins with time: time we spend getting to know your lifestyle, answer your questions and address every concern. From infants to seniors, we want our patients to enjoy an active lifestyle, not letting asthma or allergies get in the way.
