Jonathan Ellen named President of All Children’s Hospital


Jonathan Ellen, M.D., has been appointed President of All Children’s Hospital. In his new role, he will also serve as President of the All Children’s Hospital Foundation and Chairman of the All Children’s Health System Board (which oversees the All Children’s Specialty Physicians group and other entities). Dr. Ellen has served as Interim President since the retirement of Gary Carnes this past February. Prior to that time, he was the Johns Hopkins University School of Medicine vice dean for All Children’s Hospital and All Children’s Hospital physician in chief.

Since arriving at All Children’s in 2011, Dr. Ellen has led the effort for the development of mission-centric research and education initiatives, including a new pediatric residency program and translational research programs that have strengthened the integration of research and education with outstanding clinical care at the 259-bed St. Petersburg hospital.

“We are impressed with the vision, knowledge and experience Dr. Ellen brings to the position,” said Jack Kirkland, Chairman of the All Children’s Hospital Board of Trustees. “We are certain that we have selected the right person to lead All Children’s in its journey to become a top pediatric academic medical center.”

All Children’s Hospital became a fully integrated member of Johns Hopkins Medicine in April 2011. Since then, the hospital has established a new Office of Medical Education and Office of Research, launched a clinical research mentorship program and created new opportunities for collaboration between clinicians in Baltimore and St. Petersburg.

Dr. Ellen joined the Johns Hopkins University School of Medicine faculty in 1999 and in 2006 was named vice chair of the Department of Pediatrics and director of the Center for Child and Community Health Research. In the same year, he also became director of the Department of Pediatrics and Neonatology at Johns Hopkins Bayview Medical Center, where he already had established a growing research program to complement the academic and clinical missions of that campus. He is a professor of pediatrics at the Johns Hopkins University School of Medicine and a professor in the Department of Epidemiology and the Department of Population, Family and Reproductive Health in the Johns Hopkins Bloomberg School of Public Health. 

Raised in Philadelphia, Dr. Ellen graduated from Temple University Medical School and completed his residency in pediatrics at Children’s Hospital of Philadelphia. He completed a fellowship in adolescent medicine at the University of California San Francisco (UCSF) in addition to fellowships in sexually transmitted diseases at UCSF, the San Francisco Department of Health and the CDC. He has received numerous grant awards from the NIH and CDC and has authored more than 140 peer-reviewed scientific articles and 30 reviews, editorials and book chapters.
