Kelly Mather, Sonoma Valley Hospital CEO, resigns

Sonoma Valley Hospital CEO Kelly Mather has accepted a new position at another health care company but will stay on part-time during her successor’s transition before she begins her new role on Jan. 1, hospital officials said. “I think we’ve been very fortunate to have her level of skill and talent,” said Jane Hirsch, board chair of the Sonoma Valley Hospital (SVH) of Mather. “This will be a nice new challenge for her, it was something she was ready for.”
