Mount Sinai's new $70.9M multispecialty center to open next week

Mount Sinai Health System will open its new, multispecialty ambulatory facility in Wantagh next week, with plans to centralize its services in southeast Nassau County. 

The 63,000-square-foot, $70.9 million health care facility, Mount Sinai — Wantagh, is a four-story center that will offer several medical services, including oncology and cardiology, in an outpatient setting, hospital officials said. The center was designed with hospital-grade capabilities that hospital officials say will make it easier for patients to get the treatment they need, and is set to open in phases, starting July 15. The final phase will be completed in September.

“Traditionally, we have asked patients to travel to multiple sites for blood work, for X-rays, and then back to see a specialist," said Dr. Adhi Sharma, Mount Sinai's president, in a statement. "This new model puts all of that and more under one roof. It is much more patient-friendly."

Mount Sinai — Wantagh is the fifth multispecialty center for the health network and underwent nine years of development, said Kenneth Long, Mount Sinai's senior vice president and chief operating officer, in an interview with Newsday. There are also centers in Greenlawn, Manhasset, Carle Place and Long Beach.

"Our pathway has been migrating to these larger sites," Long said.

The center will eventually encompass oncology, women's care, radiology, orthopedics, pain management, cardiology, endocrinology, urology, neurology and gastroenterology. 

The first phase of opening includes the cancer center, with chemotherapy infusions coming in September. The medical staff will start seeing existing patients, and will gradually ramp up new appointments, said Tinika Henry, the director for network operations who will be the administrator for the site.

Each department has its own waiting room and staff. There are currently 109 employees on site, including nurses, medical assistants, managers, supervisors and administrative staff, according to Henry.

As each department opens, their respective outpatient facilities at other Mount Sinai locations on Long Island will be repurposed into primary care offices.

"Out in the community, we want to keep that local flavor of primary care, then just concentrate the specialties in these bigger centers," Long said.

Dr. Sunil George, a Mount Sinai nephrologist and the associate director of the Greenlawn office, will move his practice to Wantagh and serve as the center's medical director.

George said, in particular, the spacious consultation rooms will help doctors talk to patients in a private setting.

"As a clinician I really appreciate these rooms," George said. "So if I bring a family in and say, 'Let's talk about something, let's look at an image,' I can sit them down, pull up the labs, pull up the imaging, and actually go over it with them in real time."

The site was purchased by Mount Sinai in 2016 and received zoning approval in 2022 from the Town of Hempstead. The system also opened a new emergency room in May.

Mount Sinai Health System reported $11.9 billion in revenue in 2024, according to its corporate site. The system has seven hospital campuses in New York, including Mount Sinai South Nassau in Oceanside.
