After 22 years as Sharp Healthcare’s CEO, Michael Murphy plans to retire next year.

Under his leadership Sharp has grown to a $3.5 billion organization, employing more than 18,000 health care workers. Murphy's last day will be Feb. 28, 2019.

“The collective Sharp team has accomplished so much together. I am proud and humbled to have worked with all of the leaders, staff, physicians, board members and volunteers who have made Sharp such a special place,” Murphy said in a news release.

“While I am excited about my upcoming retirement, I will remain fully committed over the next 11 months to do everything possible to advance Sharp’s journey to be the best place for employees to work, physicians to practice medicine, and patients to receive care.”

Sharp’s board intends to hire a successor in the next eight to 10 months. Board Chairman Richard Freedman will lead a search committee, also drawing on an executive search firm.

“We are confident that we will have a long list of qualified health care executives who will be excited to lead Sharp into the decades that lie ahead,” Freedman said.

In addition, Daniel Gross, Sharp’s executive vice president of hospital operations, has announced he’ll retire in early 2020.

“The year 2020 will mark my 41st year at Sharp; I am grateful for the amazing opportunities it has provided,” Gross said.
