GREENWICH — A health-care professional with a background in nursing has been named the chief operating officer and executive vice president at Greenwich Hospital.

Diane Kelly was recruited from the Berkshire Medical Center in Pittsfield, Mass., to take over the position of COO in Greenwich, which had been vacant.

“An opportunity that was presented to me came at the right time in my life, both personally and professionally,” she told the Berkshire Eagle newspaper, about the move to Greenwich.

Kelly had worked for the Berkshire Medical Center for 34 years. She started out as a nurse in 1985, later assuming the directorship of patient safety and vice president of quality and safety at the Massachusetts hospital. She was also the clinical leader of the psychiatric unit. Kelly also obtained a doctorate in nurse practice and a master’s degree in business administration. The former nurse had served as chief operating officer at the Berkshire facility since 2009.

“Of course we will miss her, but at the same time we are all very proud of her,” Berkshire Medical Center CEO David Phelps said in a statement.

In Greenwich, the hospital administration said Kelly was chosen after an “extensive” search.

“Diane has a proven track record in health care administration with many years of experience in direct patient care and hospital operations. She is renowned for her ability to collaborate with physicians and ensure the success of her organization,” Greenwich Hospital President Norman Roth said in an announcement.

Kelly is replacing Sue Brown, who retired last month. Brown had been serving in the COO role, which was vacated when Brian Doran left in 2014, according to Greenwich Hospital.

Kelly’s appointment takes effect April 30.
