ST. PETERSBURG — Johns Hopkins All Children's Hospital has announced the hiring of Dr. Jennifer Arnold to lead its expanding Simulation Center.
Arnold, a nationally known neonatologist and pediatric expert in educational medical simulation, comes to Johns Hopkins All Children's in advance of the center's planned move into a new research and education building slated to open next year. The new facility will triple the center's space and expand its mission, according to the 259-bed hospital.
“Dr. Arnold will help us expand our mission to improve patient safety and outcomes for children,” says Dr. Jonathan Ellen, president and vice dean of Johns Hopkins All Children's Hospital.
