The CEO of Texas Health Resources will retire this year, the hospital system announced on Monday.

Barclay Berdan has worked at Texas Health Resources for nearly four decades and has been CEO since 2014, according to the system’s announcement. He will retire in September.

Winjie Miao, currently the system’s senior executive vice president and chief operating officer, will take over as CEO after Berdan’s September retirement.

In the meantime, the announcement said, Miao has been appointed president, a role she will assume in early April.

As the senior leadership shifts, the system has also named Laura Irvine as its new senior executive vice president and chief operating and growth officer.

The Texas Health Resources system operates nearly two dozen hospitals in the Dallas-Fort Worth area, according to the system’s website, along with dozens more primary care offices, outpatient facilities and surgery centers.

The system’s board of trustees chair, Hunter Hunt, said in the announcement that the transition is the result of “thoughtful planning.”

“Barclay’s leadership has shaped this organization in enduring ways,” Hunt said in the announcement, “and Winjie and Laura bring the experience and perspective needed to build on that foundation.”
