NORTHERN CALIFORNIA – The chief executive officer of Adventist Health’s St. Helena Hospital Region has stepped down.

On Friday morning, Bill Wing, chairman of the Board of St. Helena Hospital Region, announced the resignation of Terry Newmyer.

Hospital officials did not give a reason for Newmyer’s resignation.

Newmyer was appointed to the position in January 2009, succeeding JoAline Olson.

In a memo to employees, physicians and volunteers, Wing wrote, “I want to acknowledge Terry’s service to the St. Helena Region, the Northern California Network and to our healthcare system.”

Wing has appointed Steve Herber, MD, EVP/CMO, as interim CEO of the St. Helena Hospital Region.

In addition to his role as CEO, Newmyer served as the president of the Northern California Network of Adventist Health including the three hospitals of the St. Helena Hospital Region as well as Ukiah Valley Medical Center and Frank R. Howard Memorial Hospital in Mendocino County.

As chairman of the board, Wing will assume leadership over the Northern California Network.

Adventist Health has initiated an executive search for a permanent replacement.

In closing remarks to staff, Herber reminded them that “As caregivers of Adventist Health, our first and primary focus remains on our patients and on delivering superior care. Our mission and vision remain fully intact and as vibrant as ever. We are here, and we will live up to the promise and commitment we’ve made to our communities.”
