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.

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.

A New Heart Disease Prevention Strategy: Combining Ezetimibe & Statins

Statement by Kirk Garratt, M.D., Medical Director of ChristianaCare's Center for Heart & Vascular Health "A new study is challenging the current approach to preventing heart disease by showing that combining ezetimibe (Zetia) with statins could be a highly effective treatment for all high-risk patients, not just those who can’t tolerate higher doses of statins. Ezetimibe works by blocking the absorption of dietary fats before they reach the liver, while statins block the conversion of these fats into bad cholesterol. Clinical studies have already shown that combining moderate doses of statins with ezetimibe works as well as high doses of statins alone. This new research, which used a sophisticated method to combine results from many studies, demonstrates the potential of using this combination more routinely. The impact could be significant—potentially avoiding thousands of heart attacks and saving many lives each year. Ezetimibe has minimal side effects and is available in generic form, offering a treatment option with few barriers to widespread use. However, patients should speak with their doctor to discuss whether this combination is right for them." Learn more:

Four-Peat! ChristianaCare Achieves Magnet® — the Top Recognition for Nursing Excellence — for the Fourth Time

Hundreds of nurses and their colleagues at ChristianaCare gathered in a conference room at Christiana Hospital and listened through a livestream across the organization’s campuses and practices for an announcement they’ve been anticipating for many months. “For your commitment to nursing excellence and quality care, we are thrilled to recognize ChristianaCare with its fourth consecutive Magnet designation,” said David Marshall, JD, DNP, RN, chair of the American Nurses Credentialing Center’s Commission on Magnet Recognition. “This accomplishment is a powerful testament to your dedication to the nurses who practice there, the entire health care team, and — most importantly — the patients you serve.” Shouts erupted, balloons and streamers floated up and, in the happy commotion, there was even a little cowbell. As the only four-time Magnet-designated health care organization in Delaware, ChristianaCare has achieved this global recognition — the highest honor in nursing practice — for continued dedication to excellence and innovation, high-quality patient care and experience, nurse engagement and work culture. “Magnet designation recognizes ChristianaCare nurses are simply the best!” said ChristianaCare President and CEO Janice E. Nevin, M.D., MPH. “A fourth Magnet designation is an incredible achievement and reflects the vital importance and commitment of our nurses as we serve together with love and excellence.” ChristianaCare has more than 3,000 nurses, and they make up the largest segment of ChristianaCare’s workforce. ChristianaCare is the largest nonprofit organization and private employer in the state of Delaware. This most recent designation for ChristianaCare includes Christiana Hospital, Wilmington Hospital, ChristianaCare HomeHealth and Community Care Services, through early 2029. What it means to be Magnet “Our fourth consecutive Magnet designation means that our nurses and all of our caregiver colleagues have upheld the ANCC’s very high standards in patient care since our first recognition in 2010,” said ChristianaCare Chief Nurse Executive Danielle Weber, DNP, RN. “That is a long time to bring your ‘A’ game every day — through 15 years of change, including a pandemic — and to sustain growth in professional practice, innovation and culture. Magnet recognition raises the bar for patient care and inspires every member of our team to achieve excellence every day.” The Magnet Recognition Program — administered by the American Nurses Credentialing Center, the largest and most prominent nurses credentialing organization in the world — identifies health care organizations that provide the very best in nursing care, exceptional nurse engagement and professionalism in nursing practice. The Magnet Recognition Program serves as the gold standard for nursing excellence and provides consumers with the ultimate benchmark for measuring quality of care. The ANCC Magnet Recognition Program® has conferred Magnet status to less than 10% of hospitals and health systems in the United States. There are 621 Magnet-designated health organizations internationally. ChristianaCare was the first in Delaware to achieve Magnet designation, in 2010. For nurses, Magnet Recognition means education and development through every career stage, which leads to greater autonomy at the bedside. For patients, it means the very best care, delivered by nurses who are supported to be the very best that they can be. While Magnet is a nursing-led initiative, the designation reflects the work of caregivers across the organization. Magnet redesignation itself is a rigorous process. Health care organizations must reapply for Magnet status every four years and demonstrate adherence to the Magnet concepts for nursing excellence and engagement and measurable improvements in patient care and quality. The ANCC commended ChristianaCare on these exemplars: Advocacy for and acquisition of organizational resources specific to nurses’ well-being. particularly through the Nursing Integrative Care Program. An innovative strategy to address the shortage of certified registered nurse anesthetists in Delaware through a partnership program between ChristianaCare and Wilmington University to launch the state’s first Nurse Anesthesiology program. Outstanding nursing research engagement and growth of the nursing research enterprise especially through the Nursing Research Fellowship in Robotics and Innovation.
