Dr. Dallas is wonderful. He is is very thorough and very perfessional. He answered all my questions and made both myself and my daughter feel heard. I appreciate how he takes the time to ask questions and really listen. He is kind and courteous and has a very good bed side manner. Id recommend Dr Dallas to anyone with pediatric endocrinology needs. The nurse who called us im and took my daughter's weight, height, and blood pressure was also exceptional. She was very kind and attentive. She made both my daughter and I feel at home and comfortable.

We have been coming to Cook Children's since November of 2023 and have never had a bad experience. That includes having a major surgery, hospital stay, radiation treatments, lots of lab work, have utilized the pharmacy, and health with many staff. ALL have been nothing short of a blessing! Thank you for making such a safe and caring place for kids on all journeys and their families to come and find hope and exceptional care on all levels.

Dr. Dallas is such a great physician who genuinely cares about our girl. He goes above and beyond to make sure we understand and are comfortable with everything before we leave. He takes his time and doesn't rush. He has been one of our biggest blessings on the journey we're on with our daughter. I'm glad he is getting his retirement, but saddened that he will no longer be our Dr. All who follow in his footsteps has BIG shoes to fill.
