Chief Executive Officer of Tewksbury Hospital Sandra Akers will soon be leaving her post.

"I have been appointed as bureau director for the public health hospitals, overseeing four of the state hospitals, including Tewksbury," Akers said Thursday. The job is still under the Department of Public Health umbrella.

The bureau operates Lemuel Shattuck Hospital, Tewksbury Hospital, Massachusetts Hospital School and Western Mass Hospital.

The change in job is effective Monday, Akers said.

Akers, who started at Tewksbury Hospital in 2004 as the chief of the nursing program, has served as CEO since 2006.

"I will still be involved with Tewksbury," Akers said noting she will still have an office onsite. 

"Over the past six years we've seen tremendous growth," Akers said listing a six-bed dialysis center, a new neuro-rehabilitation program and an employee wellness program that won the Champion Award from DPH as some of the hospital's accomplishments.

"I'm excited for this opportunity," Akers said. 

As of Monday, current Chief Operations Officer Debra Torsti will serve as interim CEO until the interview process begins.
