She earned her MD from Jefferson Medical College of Thomas Jefferson University (2002), completed a dual-institutional pediatrics residency at Jefferson and Alfred I. duPont Hospital for Children, and returned to Jefferson and Christiana Care for a three-year Neonatal-Perinatal Medicine fellowship.
As Principal Investigator at Delta, she leads pediatric, maternal-fetal, and neonatal trial initiatives, bringing 17+ years of in-house neonatology through Onsite Neonatal Partners, including 11 years at Nemours Children's Hospital in Orlando, plus medical-director consulting for Blue Cross Blue Shield (2018–2020) and Centene Healthcare Management (2020–2023).
Her peer-reviewed work in the Journal of Perinatology includes a 2009 first-author study on placental pathology in very low birth weight infants of preeclamptic mothers and a 2006 paper on racial disparities in prenatal care. Earlier research earned the Philadelphia Perinatal Society's Thomas R. Boggs Jr. Research Award, and she currently leads three quality-improvement studies at the St. Joseph's/Candler Health System.
Beyond the clinic, Dr. Zook has served as a neonatology consultant in Ghana and volunteers with Mercy Ships and the Mama Project, and is a three-time recipient of the St. Joseph's/Candler "We Care" Award for Values in Action, chosen by staff and patients.
