The Emergency Department at Children’s Health℠ serves as a major referral center for Dallas County and the surrounding region, making it one of the busiest pediatric emergency medicine clinical services in the country.

“Most people would be surprised at the number of patients we see every day, the number of highly skilled doctors involved in the care of each child, and the number of staff available to meet all of our patients’ needs,” says Dr. Halim Hennes, director of the Division of Pediatric Emergency Medicine.

Specially qualified doctors and staff and a facility exclusively devoted to providing age-appropriate and immediate services to ill and injured infants, children and teens is a distinctive competency of the department.

“Children are not just small adults. They have different anatomy, their disease process is different from adults, and the way they react to pain is different. It takes special skill and knowledge to effectively manage and treat pediatric patients. Having all the different kinds of pediatric subspecialists, trained pediatric technicians, and pediatric nurses is what makes a difference for our patients,” he says.

Dr. Hennes was motivated to become a doctor in his early years growing up in Egypt.

“In my freshman year of high school, I used to accompany elderly members of my family to their doctor appointments,” he explains. “Our family physician was an angel and he always talked to me about medicine. He became my idol and that was how my interest in medicine started.”

While the emergency medicine environment is a stressful one, Dr. Hennes is inspired by his young patients.

“Taking care of sick children, helping them and their families and watching them get better is what brings me and my entire staff together every day,” he says.

Dr. Hennes is certified by the American Board of Pediatrics. He earned his medical degree from Ain Shams University in Egypt and served as a pediatric intern at the Medical College of Wisconsin, where he also completed his residency and an emergency medical service fellowship.

He is a Fellow of the American Academy of pediatrics and a member of the Ambulatory Pediatric Association, the National Association of EMS Physicians, the Society of Academic Medicine and the Wisconsin Medical Society. He is professor of Pediatrics and Emergency Medicine at UT Southwestern Medical Center with research interests in brain injury, pain management and pediatric sedation. Dr. Hennes has written more than 70 research publications and book chapters and received many federal grants to support his research activities. He also served on many national and regional professional societies.

Outside of his practice, he enjoys swimming and reading.
