Dr. Mark Schnellinger is a writer and longtime pediatric emergency medicine physician. He was educated at Maimonides Medical Center and completed a fellowship in pediatric emergency medicine at the University of Minnesota. He currently works at Children's Minnesota.

During his time in the pediatric emergency room, Dr. Schnellinger noticed that many children and their caregivers were often scared and vulnerable as they dealt with the realities of illness and injury. He wondered if there was a way he could help children and their caregivers understand what was going on inside their body in an engaging and fun way.

The Medicine Stars became his answer to this common struggle—a series of books that teach middle-grade children about illness and injury, not through shots and doctor's visits, but rather through captivating adventures that use real-life medical metaphors.
