In her role, Leffler leads the ChristianaCare Center for WorkLife Wellbeing and strategies to enhance the professional fulfillment and well-being of ChristianaCare’s nearly 14,000 caregivers, overseeing advocacy programs and initiatives to optimize their experience and foster a culture of well-being throughout the organization. She works closely with leaders across key departments to address factors impacting caregiver well-being.


Leffler most recently served as the inaugural chief wellbeing officer at Nemours Children’s Health, where she helped the organization to achieve the 2022 Joy in Medicine distinction from the American Medical Association for prioritizing proven efforts to enhance the professional fulfillment of physicians. There, she established a Center for Associate Wellbeing; led the first systemwide assessment to strategically address well-being and burnout; and implemented a peer support program and expanded the scope of resources available to support the emotional and mental health needs of employees. In collaboration with organizational leaders, she supported targeted clinical team assessments and systems-based interventions to foster well-being.


Prior to this role, Leffler served as a pediatric rheumatologist at Nemours and as an assistant professor of pediatrics in the Division of Rheumatology at Thomas Jefferson University.


Since 2017, Leffler has served as the course director of the Chief Resident Leadership Training Program for the Accreditation Council for Graduate Medical Education (ACGME). In response to the COVID-19 outbreak, she co-chaired ACGME’s National Task Force on Well-Being.


She and her team developed a national graduate medical education well-being community, which she continues to convene, to understand the evolving challenges and share strategies to improve well-being. She represents the ACGME as a coach for the National Academy of Medicine Action Collaborative on Clinical Well-Being and Resilience. She also serves as a consultant to the Professional Satisfaction team at the American Medical Association.


Leffler earned her medical degree from the Philadelphia College of Osteopathic Medicine, followed by a residency in pediatrics at Nemours and Thomas Jefferson University Hospital, where she served as chief resident. She subsequently trained in pediatric rheumatology at Nemours and Jefferson. She also earned a Master of Public Health from Temple University and studied chemistry at St. Joseph’s University.


Recently, Leffler completed the Georgetown Executive Leadership Certification Program.
