Meet Dr. Mary C. Brennan
I knew early in high school that I wanted to be a physician. My desire came from watching my parents struggle with health issues. As I progressed through medical school, I knew that pediatrics was the field for me. I wanted to partner with parents or caregivers in a way to help them find the right path. I'm passionate about providing parents and then older children/teens with information and recommendations that can help them thrive physically and mentally.
I attended LSU in Baton Rouge for undergraduate, and then to LSU School of Medicine in New Orleans. I studied pediatrics at Baylor College of Medicine and Texas Children's Hospital in Houston.
In 1990 I moved to Fort Worth and opened my private practice with Deborah Hucaby M.D. When Cook Children's formed the physician network, we were one the original practices to join. Shortly, after that Dr. Alice Phillips joined me in our current practice.
As a pediatrician, I'm blessed to see the children move from total dependency to independence through childhood to adolescence.
When not at work, I love spending time with my three sons. We love being outdoors with our 3 dogs, riding bikes along the many trails in Fort Worth, volunteering at our church, or trying out new hobbies - like fly fishing.
Dr. Carol Mary Brennan is an amazing doctor. She has great bedside manner and makes sure that we leave with knowledge and they we're comfortable with the recommendations, suggestions or medication she gave us. Thank you. – Patient family

Dr. Brennan went out of her way to listen to my daughter today. She had concerns about her autism and anxiety and the doctor took time to really listen and let my daughter talk until she felt better about her concerns. Dr. Brennan included me after they talked and filled me in with general information about their discussion. We both left the appointment today feeling good about what was discussed.
