Responding to a sudden vacancy, the Cancer Treatment Centers of America is moving the CEO of its Chicago-area hospital to fill the same post at its Georgia facility.

The Illinois-based company said Anne Meisner will be the head of CTCA’s hospital in Newnan, in the southern part of metro Atlanta.

She will replace Kane Dawson, who abruptly resigned three months after the hospital opened.

The company said Meisner, a registered nurse, has been with CTCA for more than 20 years. For the last six years, she has been president and CEO of CTCA’s Midwestern Regional Medical Center in suburban Chicago.

CTCA said Meisner created a care model where all services desired by cancer patients are delivered in one location. She also expanded Midwestern’s stem cell and cell therapy program; expanded its surgical services and tripled its surgical space; and opened a Quality of Life clinic, the company said in a press release.

Cancer Treatment Centers of America Chief Operating Officer Roger Cary has been  serving as interim president and CEO of the Georgia hospital.

The $150 million Georgia facility is the company’s fifth regional hospital. It has committed to getting most of its patients from outside the state.

Dawson was hired as the hospital CEO in 2011, a year before its opening. Prior to that appointment, he was the chief operating officer for CTCA at Eastern Regional Medical Center in Philadelphia, where he helped open the facility in 2005.

The company has not commented on the reasons for Dawson’s departure from the Newnan hospital.

Meisner and her family will relocate to Newnan before the end of the year, CTCA said.
