Winnie Mack, tapped in April to lead Nassau University Medical Center to help turn around the struggling public hospital, will depart after six months as president and chief executive, NuHealth chairman George Tsunis said.
Mack was serving in the hospital’s top job through a temporary partnership between Northwell Health of Manhasset and NuHealth, the public benefit corporation that runs NUMC. The partnership will continue, Tsunis said.
Northwell, the state’s largest health system, entered into a multiyear partnership in which it would provide management consultants on a three-year basis and devise a five-year strategic plan for NUMC and related facilities, including the A. Holly Patterson Extended Care Facility in Uniondale.
Northwell gave notice to NuHealth on Monday morning that Mack would be leaving Oct. 15, Tsunis said. Mack was to be paid $550,000 per year with NuHealth reimbursing Northwell $275,000 — six months' pay — as long as the state reimbursed the corporation, Tsunis said.
Mack’s agreement to work at NUMC was for a maximum of two years, and there was an option every six months for her to continue, Tsunis said. Mack reported to NuHealth's board.
“Winnie Mack will not be continuing on as interim president and CEO past her six-month contract,” Tsunis said in an interview. “It was always meant to be short term. We’re all incredibly grateful for Winnie and for all she has done for NUMC and wish her well in the future.”
Mack had worked as senior vice president of operations for Northwell.
Jason Molinet, a Northwell spokesman, said Northwell had "no comment at this time." Mack did not respond to requests for comment.
Tsunis said NuHealth will search for Mack's replacement with the help of Northwell's talent and acquisition department.
In April, Michael J. Dowling, president and chief executive of Northwell Health, said in a statement that Northwell "believes we have a social responsibility to assist NuHealth, which is an indispensable asset and critical resource for residents of Nassau County.”
The Northwell-NuHealth venture was announced last Nov. 1. Tsunis said Northwell was to help NUMC achieve "a transformative rebirth — a turnaround."
Last year, NuHealth's operations lost $46.6 million, compared with a $25.7 million operating loss in 2017. The health system's operating budget last year was $587.6 million.
An audit in June by Grant Thornton LLP, a Manhattan accounting firm, said NuHealth “has experienced recurring operating losses” and “is dependent on the continuation of federal, state and local subsidies, certain of which are scheduled to end or be reduced. These matters raise substantial doubt about NHCC’s ability to continue as a going concern.”
