St. Elizabeth's hospital CEO talks about the move from Belleville to O'Fallon on Nov. 4.

Just months after spearheading the opening of a new hospital, the president and CEO of St. Elizabeth's Hospital has resigned to pursue new career opportunities, the hospital's parent company announced Tuesday.

Her resignation is effective immediately.

Peg Sebastian joined Hospital Sisters Health System in 2009 as president and CEO of St. Joseph's Hospital in Highland. In January 2016, she was appointed president and CEO of St. Elizabeth's.

As CEO, Sebastian oversaw the closure of St. Elizabeth's Hospital in Belleville and the opening of the new hospital in O'Fallon. She also oversaw projects at St. Joseph's.

St. Elizabeth's opened on Nov. 4 just as the Belleville facility closed.

Prior to her tenure at HSHS, Sebastian was president and CEO of Sebastian Group, LLC, a healthcare consulting company specializing in construction, operation and planning for new facilities.

Patricia L. Fischer, chief operating officer of HSHS St. John's Hospital in Springfield, will serve as interim president and CEO for St. Elizabeth's. The hospital group will conduct a national search for a permanent president and CEO.

Jim Dover, president and CEO of the system's Southern Illinois Division, will provide on-site support to the hospital's leadership team during the interim.

“We appreciate Peggy’s many contributions to HSHS, in particular her leadership and oversight of our two major construction projects in Highland and O’Fallon. We wish her the very best as she begins another chapter in her career,” Dover said.
