Rob Deininger named president/CEO of AdventHealth’s East Florida Division

AdventHealth has named Rob Deininger president and CEO of its East Florida Division, which includes facilities in Volusia, Lake and Flagler counties, effective May 4, 2025.

Deininger replaces Audrey Gregory, who was recently named president and CEO of AdventHealth’s newly formed Multi-Division Delivery Network. Deininger will report to Randy Haffner, president and CEO of AdventHealth Florida.

“Rob is a tried-and-true leader,” Haffner said. “His depth of knowledge and solution-oriented, strategic approach, paired with his passion for our mission, is certain to continue supporting AdventHealth’s vision and growth in East Florida.”

In his new role, Deininger will oversee the strategic direction, development and execution of key strategies that support the total network of care and help build influential relationships with key constituents, community partners and consumers. He will also serve as the primary executive for the East Florida Division’s partnership with HealthFirst in Brevard County.

After 13 years as a commercial airline pilot, Deininger joined AdventHealth in 2008. Throughout his time with the organization, he has served in progressive leadership roles, including president and CEO of AdventHealth Fish Memorial. During his time there, Deininger helped to grow and expand services through a new hospital-based, offsite emergency room and a 140,000-square-foot expansion of the hospital campus, which opened in April 2021.

He has also previously served as vice president of operations for AdventHealth Orlando and vice president of research operations. Notably, Deininger served as system incident commander for AdventHealth’s pandemic response team. Most recently, he served as market CEO for the AdventHealth Central Florida Division’s quaternary hub, comprised of AdventHealth Orlando, AdventHealth Winter Park, AdventHealth for Women and AdventHealth for Children.

“I’m honored and humbled by the opportunity to lead our East Florida Division,” Deininger said. “Dr. Gregory has built upon the division’s firm foundations during her tenure, and I look forward to continuing that momentum to bring our promise of wholeness to life for the community.”

In addition to a Six Sigma Black Belt, Deininger holds a bachelor’s degree in technology as well as a master’s in business administration from Andrews University in Berrien Springs, Michigan. He is an active member of the American College of Healthcare Executives, the American Society for Quality and the Society of Research Administrators.
