About Family Allergy & Asthma Care
We’ve brought peace of mind to families for over 25 years. Our friendly, caring team helps both adults and kids find relief from stressful food allergies, bothersome environmental allergies, and debilitating asthma.
Being moms and caring for our own families has given us a deeper understanding of how to care for you and your family. We understand the need for early morning and evening clinic hours, educational resources, a listening ear, and a caring heart. As board-certified allergists we have completed the highest level of training in allergies, asthma, and immunology which allows us to offer you expert care. We’re your devoted partners in solving your healthcare needs.

Fellowship-trained, board-certified allergists. And, we’re also moms.
Mary Hudelson, MD – DABAI, Director
Treating allergy patients is often like solving a mystery and requires time spent listening and gathering data in order to create a treatment plan that works! Now that’s truly fun!
When I founded FAAC in 1993, I wanted to do things differently to provide an innovative patient-centered experience. That’s why, when you visit us, we are able provide services such as allergy testing, sinus CT scans, and lung function tests in the office at the same time as your appointment; we offer extended office hours; and the same clinical team member stays with you through your entire visit.
My military service as an Army reservist activated for Operation Desert Storm was a life-changing experience. Not only did I meet my husband, I solidified my passion to care for entire families because it was my job to care for the military dependents (children and spouses) of Aviano Base in Italy while their family member was deployed. Upon my return to the U.S., I chose allergy/immunology as a specialty, partly because I would be able to care for all ages of people – babies to centenarians. And that’s just what I have done! And now, I’ve been in practice long enough that I often get to see the children of the children I cared for!
I love being an allergist! Every day, I am thankful for the opportunity I have to compassionately partner with patients and family members to make a positive difference in their lives.

I am passionate about improving every patient’s quality of life through better control of their asthma and allergies. I had allergies as a child and my treatment was life changing for me. I want to make that possible for others. It is so rewarding when one of my patients comes in and tells me how their asthma no longer hinders them from sports or their allergies no longer hinder them from their outdoor activities.Diplomate: American Board of Allergy & Immunology 1995- Present

I want to make that possible for others. It is so rewarding when one of my patients comes in and tells me how their asthma no longer hinders them from sports or their allergies no longer hinder them from their outdoor activities.
My interest and passion in allergies and asthma began at an early age. My dad was one of the early allergists in Texas. When he would come home in the evenings, I saw the joy he received from treating allergy and asthma as well as helping his patients find improved health. My dad was ahead of his time basing treatment for patients on the local pollen he counted at his station on the top of a Dallas building in the early 1950’s. For 15 years, I have enjoyed being the director of our nationally–certified pollen counting station which is one of two certified stations in the metroplex. We provide counts for other allergists in our region which helps everyone better care for families.
As a mom, I’ve experienced the panic and anxiety of raising kids with food allergies and asthma. I know the impact on families firsthand, and it’s created an innate passion for my practice and learning all I can to treat patients of all ages – infants to elders. Just like my colleagues, I’m double-boarded in allergy and immunology, as well as internal medicine. I’m also a fellow of the American Academy of Allergy and Immunology. Through my experience as an associate professor of medicine at UT Southwestern, being a mother, and doctor, I know that listening to patients and working with them to find the best treatment for their lifestyle is critical.

I am passionate about helping patients get to the root of their problems and work together to improve their quality of life. My goal is to empower patients through teaching/education regarding their condition and find solutions that work specifically for them. My training at Cincinnati Children’s Medical Center, a top pediatric allergy hospital, has given me knowledge of the most up-to-date and excellent treatment options. I am excited to bring that knowledge to my patients every day!Fellowship: Cincinnati Children’s Hospital Medical Center

NANA MIREKU, md – DABAI, PEDIATRIC ALLERGIST
I am passionate about helping people be set free from the limitations caused by allergies and asthma. Having suffered with allergies since childhood I have experienced firsthand the positive difference allergy treatment can bring.
My favorite thing is to take care of a child who has been socially impacted by their food allergies. I love it when they can experience the freedom to attend birthday parties, eat lunch with others at school or go to outings with friends. Empathizing with a parent whose child has food allergies is especially meaningful to me as I am also the parent of 2 children with food allergies. It can feel scary and overwhelming for parents to navigate the complexities of having a child with a life-threatening food allergy. My goal is to walk this journey alongside parents and their food allergic child to help them alleviate their fears and meet their goals. Educating and partnering in this way is truly my passion.
I love people and I love to learn. While I was training to become a pediatrician, I did a rotation in the allergy/immunology clinic at Children’s Hospital of Michigan and fell in love with the everchanging science of allergy. I completed an allergy fellowship at Detroit Medical Center in 2008 and started doing what I love.
I have lived in north Texas for the last 12 years practicing pediatric allergy, asthma & food allergy.

Compassionately caring for your family.
Angelica Ybanez, Board Certified, PA-C
I have always been passionate about health and wellness. For 9 years, I cared for patients in a primary care setting and truly enjoyed my patients and diligently strived to help them establish a healthier lifestyle. It’s now been my privilege to care for patients in the allergy and asthma specialty for the past 10 years at Family Allergy & Asthma Care.
I enjoy developing relationships with my patients at FAAC and always want to communicate clearly and compassionately to provide a collaborative approach. I want each patient to receive the highest level of personalized care and clearly understand their healthcare plan.
I enjoy all aspects of allergy and asthma but one area of allergy I am truly passionate about is food allergy. It brings me such joy to see the food allergy patients achieve their individual goals. Many of the food allergy patients I see come in on a weekly basis for oral immunotherapy and I truly look forward to our time together.
I want to make the process easy, clear and comfortable for each one of them and partner with their families to make life less challenging and develop a pathway to freedom. That freedom can make simple things like going out to eat a joy instead of a fear. My goal is to help make their life easier and less challenging. I am blessed to be the Mom of twin boys. I love spending time with my family, playing sports and being outdoors. It is rewarding to me to be in allergy and asthma where I can help other people feel better and be able to spend time with their family doing the things they love!

For 19 years, I cared for patients as a physician assistant in a primary care setting. This opportunity has given me a unique understanding of how many factors can influence a person’s quality of life. There are many aspects of life outside of healthcare that can affect a person’s wellbeing including financial and social issues, further complicated by the fast-paced world in which we live.
My goal is to treat the whole person, giving our patients the tools they need to live their best life. I’m here to help people find confidence and comfort during treatment of their allergy and asthma conditions.
Living with allergies and asthma can limit many aspects of a person’s life, including simple things such as being outside, going to a new restaurant or exercising. An open discussion about patients’ needs is crucial when developing an effective treatment plan. Voted in the top 10 percent nationally for effective provider communication, I know the importance of a two-way dialogue. At the center of appointments is listening and effective communication. I’m honored to care for people and to have the opportunity to develop a relationship with them. It is what I want as a patient and for the care of my husband and two daughters.
