Gaithersburg-based Adventist HealthCare announced that Patsy McNeil, MD, MBA, FACEP, Executive Vice President and System Chief Medical Officer, will leave the organization on November 6, 2026, to pursue a new professional opportunity with Riverside Health in Newport News, Virginia.
McNeil has served as Adventist HealthCare’s second-in-command, overseeing clinical operations, quality, patient safety, medical staff affairs and strategic healthcare transformation initiatives across the health system’s hospitals, ambulatory care sites and physician offices.
McNeil joined Adventist HealthCare in 2018 as Chief Medical Officer of Adventist HealthCare Shady Grove Medical Center and went on to hold progressively senior leadership positions within the organization.
During her tenure, McNeil helped lead several major systemwide initiatives. Adventist HealthCare became the only health system in Maryland to have all of its hospitals receive “A” grades from The Leapfrog Group in Spring 2026. She also oversaw the system’s clinical response to the COVID-19 pandemic, which Adventist HealthCare said resulted in an inpatient COVID mortality rate of less than half the national average.
According to Adventist HealthCare, McNeil’s leadership also helped reduce medical staff turnover by nearly 20% and contributed to improvements in Maryland Quality Program performance, which went from a net loss to $16.8 million in revenue. Her work also focused on strengthening collaboration between physicians and executive leadership and improving physician engagement.
“Patsy helped shape Adventist HealthCare into a stronger and more innovative organization,” said John Sackett, President and CEO of Adventist HealthCare. “Her leadership elevated quality and patient safety, strengthened physician partnerships and helped position our system for the future. We are deeply grateful for her dedicated service.”
McNeil called serving Adventist HealthCare “one of the greatest privileges of my career,” adding that she is proud of what the organization accomplished and grateful for the caregivers, physicians and leaders she worked alongside.
