With more than a dozen years of experience in promoting wellness, Medical Director of Child Wellness Stephanie Walsh, MD, is a leader in the field. A board-certified pediatrician and diplomate of the American Board of Obesity Medicine, Dr. Walsh played an instrumental role in establishing the Children’s Strong4Life movement.

Surgeon-in-Chief, Children’s Healthcare of Atlanta
Children’s Healthcare of Atlanta Surgeon-in-Chief Mark Wulkan, MD, is an expert in advanced, minimally invasive surgical techniques. The exclusive surgeon for the Strong4Life Clinic, he introduced pediatric bariatric surgery to the clinic in 2004. Seeing children’s lives arrested by obesity and working with patients who have turned to bariatric surgeries, like gastric bypass surgery, inspired Dr. Wulkan to play an active part in bringing more specialized support to kids and their families at Children’s Strong4Life Clinic. A parent to three kids, Dr. Wulkan is a huge proponent of role modeling healthy habits beginning early in life. He says his biggest parenting challenge is finding time to eat together as a family.

Wulkan has been repeatedly recognized by Atlanta Magazine in its annual “Top Doctors” issue. He graduated from Emory University School of Medicine in 1989 with summa cum laude honors and completed his residency in general surgery at Jackson Memorial Hospital Medical Center at the University of Miami in 1994. He also completed a fellowship in pediatric surgical critical care at the University of Pittsburgh and Pittsburgh Children’s Hospital in 1995 and a research fellowship at the University of Alabama and The Children’s Hospital of Alabama in 1996, where he completed an additional residency in pediatric surgery in 1998.

Wulkan is an avid running enthusiast and belongs to a running group made up of his colleagues on the medical staff here at Children’s.
