MultiCare Health System will say goodbye to president and CEO Diane Cecchettini, due to her just-announced plans for retirement.

The health system, with five hospitals and numerous clinics around the South Sound, and roughly 10,600 workers, is the largest private employer for Pierce County.

Formerly an employee of UCLA Medical Center in Los Angeles and Sacramento's Sutter Health System, Cecchettini came to MultiCare as vice president for patient services in 1989. A decade later, she became the first woman and nurse hired as president and CEO.

A recruiting committee is currently in place and actively searching for a new MultiCare leader before Cecchettini retires in the second quarter of 2014.
