Mount Sinai South Nassau marked a major milestone on Oct. 21 with the dedication of its new $150 million Feil Family Pavilion — a four-story, 100,000 -square-foot addition that expands the hospital’s emergency, surgical and critical care services while positioning it to introduce open-heart surgery next year.
Hospital leaders, community members and elected officials joined Mount Sinai Health System executives for the opening ceremony and ribbon cutting, celebrating the largest capital project in the Oceanside hospital’s history. The new pavilion features an expanded Fennessy Family Emergency Department, 40 intensive and critical care beds and nine advanced operating suites expected to open in the spring.
The hospital’s president, Dr. Adhi Sharma, called the opening “an important milestone in our long history of serving the South Shore of Long Island,” noting that the new design is already helping reduce wait times and improve care in the emergency department. The project, he added, reflects a decade of planning to meet the growing health needs of the surrounding communities.
For Sharma and the hospital’s leadership team, the dedication represented the culmination of years of effort and the foundation for what comes next. The pavilion is part of a 10-year master plan to expand services, enhance technology and continue transforming Mount Sinai South Nassau into a regional medical hub.
“The facilities are so modernized and patient-centered that our staff are able to take even better care of the patients,” Sharma said. “We designed it to be so that patients’ families are now able to stay with the patients because there is more space.”
The new operating suites are designed for both minimally invasive and open procedures and will house the hospital’s forthcoming open-heart surgery program, which will be the first on Long Island staffed and overseen by cardiac surgeons from the Mount Sinai Fuster Heart Hospital in Manhattan. U.S. News & World Report has ranked Fuster Heart Hospital No. 2 in the nation for cardiac care.
“Our patients and their families should not have to travel to North Shore or Manhattan to receive this kind of advanced care,” Sharma said.
The pavilion was made possible through what Sharma coined the Feils’ “philanthropic support.” Jeffrey Feil, CEO of The Feil Organization — a family-owned real estate investment, development and management firm — and his family have contributed more than $18 million to Mount Sinai South Nassau over the years, with another $1 million recently pledged. Their gifts have supported emergency medicine, cancer care and, most recently, the expansion of critical and surgical services.
Hospital officials said the Feil family’s generosity embodies the kind of partnership that drives Mount Sinai’s mission. Tony Cancelieri, co-chair of the hospital’s Community Advisory Board, praised the family’s ongoing commitment, explaining that their support “has always been rooted in a very genuine and deep admiration for the hospital’s work to improve the lives of South Shore residents.”
Dr. Brendan Carr, president and CEO of the Mount Sinai Health System, said the pavilion reflects the strength of the partnership between the Oceanside hospital and the broader health network. “We’re strongest when we work together,” Carr said.
In addition to expanding space and capacity, the pavilion introduces a range of design features and medical technologies focused on patient comfort and efficiency. The hospital’s critical care footprint has doubled, allowing Mount Sinai South Nassau to treat more patients with advanced conditions while giving families a more supportive environment during recovery.
“The new design is already improving patient care,” Sharma said, “and it’s just the beginning of what this facility will make possible.”
The ceremony concluded with a ribbon cutting and an invocation from Rabbi David Lerner, of Congregation B’nai Sholom-Beth David, who told the crowd, “Together we can build a caring society, piece by piece, hospital by hospital, community by community.”
