Mount Sinai South Nassau continued its expansion to meet the acute and emergency medical needs of the South Shore of Long Island with the planned opening of the Fennessy Family Emergency Department as the first phase in the opening of a new, four-story patient pavilion.

Fennessy Family Emergency Department

Mount Sinai South Nassau has opened the Fennessy Family Emergency Department, the first phase in the rollout of the newly constructed Feil Family Pavilion, continuing our expansion to meet the acute and emergency medical needs of the South Shore of Long Island. Named in recognition of Joseph J. Fennessy, the hospital’s former longtime Board Chair, and made possible by a significant gift by the Fennessy family, the modern and expanded Emergency Department doubles its previous footprint and capacity and is a cornerstone of the four-story, 100,000-square-foot Feil Family Pavilion, the rest of which will open in the coming months.

The Fennessy Family Emergency Department is the size of a football field and has the capacity to see approximately 80,000 patients annually. The Emergency Department features centralized nursing stations for direct oversight of patient rooms, bedside triage, and a state-of-the art trauma unit with an adjoining radiology bay. Designated a Level II Trauma Center by the American College of Surgeons, the Fennessy Family Emergency Department’s new trauma suite, which opened in 2023, includes three spacious care bays to facilitate the flow of trauma team members as they care for patients with life-threatening injuries. Each trauma bay is equipped with advanced medical technologies, including imaging systems that provide unobstructed viewing for intubations, difficult and emergent airway management, and bronchoscopy procedures. The suite can surge to six treatment areas in the event of a mass casualty event.

New Location

The Department’s main entrance for drive-up or walk-in patients has moved from Washington Avenue to the east side of Oceanside Road south of Oswald Court and north of Nassau Parkway while the entrance for ambulances remains on Nassau Parkway.

Feil Family Pavilion

The Pavilion is named after the family of Jeffrey Feil, a longtime Rockville Centre resident who is the Chief Executive Officer of the Feil Organization, a Manhattan-based real estate development firm, and his parents Louis and Gertrude Feil. Mr. Feil and his family have been longtime supporters of Mount Sinai South Nassau and have graciously donated more than $17 million to the hospital in the past several years.

The Feil Family Pavilion will include 40 new intensive and critical care beds and nine new, modernized operating suites. The pavilion’s expanded Intensive and Critical Care units, which double the current footprint, will allow Mount Sinai South Nassau to meet the region’s rising need for critical care services, as demonstrated during the COVID-19 pandemic. The operating room and its surgical suites will be configured and designed to accommodate this era’s nonstop advances in surgical technologies and equipment. The combined impact of the redesigned and larger operating room will allow Mount Sinai South Nassau and its staff of surgeons to increase its surgical scheduling capacity to accommodate projected volumes in same-day, elective, and emergency surgeries. The new operating suites also could pave the way for an open-heart program at the Oceanside campus, pending Department of Health approval.
