Healthcare's Leadership Bench Turns Over: Hackensack Meridian, Keck Medicine, ChristianaCare Name New Chiefs

Healthcare's executive ranks are churning at a pace worth tracking. Over the past several weeks, at least a dozen organizations, spanning hospital systems, insurers, trade associations and health tech vendors, have announced CEO transitions, new C-suite hires or retirements. The pattern is not random. It reflects both the natural end of long tenures built during the 2010s consolidation wave and a scramble to install leaders who can navigate AI, data infrastructure and cost containment.

The headline move belongs to Hackensack Meridian Health. CEO Robert C. Garrett will retire on June 30, 2027, after a run that began in the early 1980s at Hackensack University Medical Center. He became president and CEO of Hackensack University Health Network in 2009, then co-CEO after the 2016 merger with Meridian Health that created New Jersey's largest health system. Garrett will stay on as CEO emeritus for a year to smooth the handoff. Under his watch, the nonprofit grew to 18 hospitals, nearly $10 billion in revenue and more than 500 patient care locations, and opened the Hackensack Meridian School of Medicine, the state's first new medical school in decades. Board Chair Keith Banks credited him as "the driving force behind HMH's unprecedented growth and transformation." A successor is expected before year's end.

That kind of multi-decade tenure is becoming rarer. At the Association of American Medical Colleges, President and CEO David J. Skorton will retire June 30, 2027, closing a run that began in July 2019 and included steering the organization through the pandemic. Skorton previously led the Smithsonian Institution, Cornell University and the University of Iowa. A search is underway.

Hospital and academic medicine transitions

Keck Medicine of USC is undergoing a broader shake-up. CEO Rodney Hanners steps down September 24 after six years, during which he expanded the Los Angeles system into Pasadena and the San Gabriel Valley. Steven Shapiro, M.D., currently senior vice president for health affairs and a former UPMC president, takes over, though the university is trimming the role's scope, shifting oversight of some health science schools back to the provost so Shapiro can focus on the academic medical enterprise. Beneath him, Chief Clinical Officer David Peng, M.D., becomes deputy executive vice president for health affairs, and Keck Medical Center CEO Marty Sargeant adds the title of system chief operating officer, both retaining their existing roles. Separately, Keck School of Medicine Dean Carolyn Meltzer is leaving to become president of the Radiological Society of North America, with pharmaceutical school dean Vassilios Papadopoulos stepping in on an interim basis.

ChristianaCare completed a leadership handoff of its own on September 1. Jenn Schwartz, who joined the Wilmington, Delaware system in 2018 as chief legal officer and was named executive vice president and chief strategy officer earlier this year, is now president and CEO. She succeeds Janice Nevin, M.D., who spent 23 years at the nonprofit, the last 12 as CEO, and is credited by the board with expanding the system's footprint and deepening investment in underserved areas. ChristianaCare runs three hospitals with 1,430 beds alongside a network of primary and outpatient care sites.

Johns Hopkins Health Plan has taken an interim approach after CEO James Holland departed in mid-August to become president of Medicaid at Humana. Chief Financial Officer Daniel Chojnowski, who has held that post for seven years, will lead on an interim basis while a permanent search continues. The insurer framed the move in a LinkedIn post as one meant to "provide stability and trusted guidance," describing Chojnowski as embodying "the modern CFO" evolved into a strategic partner.

Elsewhere, the moves skew toward finance and technology. Insurer Centene named Bradley Bolivar chief information officer effective August 31, succeeding the retiring Brian LeClare. Bolivar arrives from Fannie Mae, where he oversaw technology infrastructure and cybersecurity strategy. CEO Sarah London framed the hire around AI as "not just business enablers, but strategic capabilities." The Blue Cross Blue Shield Association tapped Dan Serrano, previously CFO for Aetna's Mid-Atlantic Region with stops at ChenMed and Healthfirst, as senior vice president and CFO. Teladoc Health brought in Michael Grasher, a three-decade insurance and financial services veteran most recently CFO at IFG Companies, as its new CFO.

Health tech is seeing its own turnover. Health Catalyst named Simeon Kohl CEO, President and board member effective September 14. Kohl previously led Performant Healthcare through a strategic turnaround that ended in its roughly $670 million sale to Machinify. Outgoing CEO Ben Albert shifts to chief business officer and exits the board; during his tenure he divested the Vitalware unit, a move that let the company retire its roughly $160 million credit facility. Cotiviti, meanwhile, appointed Erin Schmuker, formerly president of integrated pharmacies at OptumRx, as chief operating officer to scale its operating model. Kaiser Permanente added Shaun Smith, previously chief people and culture officer at NewYork-Presbyterian, as executive vice president and chief people officer effective October 12.

The American Medical Association also made a notable AI-focused hire, naming Jennifer Goldsack, founder and CEO of the Digital Medicine Society, as senior vice president and inaugural leader of its Center for Digital Health and AI. The center has already produced surveys tracking rising physician confidence in AI tools and persistent barriers to wearable data adoption. AMA CEO John Whyte, M.D., called it "a defining moment for medicine" in announcing the hire.

On the policy and industry-group side, the Pharmaceutical Care Management Association named CVS Caremark President Ed DeVaney as board chair, succeeding Express Scripts and Evernorth president Adam Kautzner, a rotation between two of the PBM industry's "Big Three" firms. Elevance Health named Patrick Fox, M.D., president of Carelon Behavioral Health, drawing on his prior role leading Wellpoint New Jersey and the company's Colorado Medicaid plan.

The Bottom Line

None of these moves individually reshapes an industry. Collectively, they point to a leadership market in transition: long-serving hospital CEOs are exiting on their own terms, insurers and tech vendors are prioritizing finance and data expertise, and organizations across the spectrum are building dedicated AI leadership rather than bolting it onto existing roles. For investors and operators watching healthcare's cost and technology trajectory, the composition of these new leadership teams, particularly who gets hired to run digital health, data infrastructure and financial strategy, will matter more than the retirements themselves.
