A 20,400-square-foot surgery center is opening this month at 371 Old Country Road in Carle Place, and the name over the door belongs to one of the largest academic health systems in New York. Mount Sinai Health System announced Tuesday that Peakpoint Central Nassau Surgery Center is opening in September, bringing outpatient operating rooms to a stretch of Old Country Road most Nassau drivers pass without a second look.

What is actually inside

The center holds two operating rooms, two procedure rooms and 17 recovery bays. Three of those bays are private rooms, and three are built for 23-hour stays, which is the detail worth pausing on. Ambulatory surgery means you go home the same day, and for most procedures that is exactly what happens. The 23-hour rooms cover the cases in between: surgeries that do not need a hospital admission but do need a night of monitoring before the drive home. A freestanding center that can keep a patient overnight can take on procedures a simple same-day facility cannot.

Nine specialties are moving in at once: gastroenterology, gynecology, ophthalmology, orthopedic and spine surgery, otolaryngology, pain management, plastic surgery, podiatry and urology. That list covers most of the routine surgical care a family needs over a lifetime, from a colonoscopy to a cataract to a knee.

Who is behind it

Peakpoint Central Nassau is a joint venture between Mount Sinai, a group of its surgeons and Merritt Healthcare, a company that develops and runs ambulatory surgery centers. The medical director is Michael Gorin, a Mount Sinai urologist, who framed the center as the middle piece of a map the system has been assembling across Long Island, with care hubs already operating in Wantagh and Greenlawn and the new Carle Place site connecting them.

One design choice matters more than the square footage: the operating rooms are open to Mount Sinai physicians and to non-affiliated surgeons from across the region. That makes the center less like a private clubhouse and more like infrastructure, a place where a Long Island surgeon can book a modern operating room without sending the patient through a Manhattan lobby.

Old Country Road is quietly becoming a medical corridor

The new center is not arriving alone. Mount Sinai Doctors-Carle Place already operates a multispecialty office a few doors down at 393 Old Country Road, with primary care, cardiology, dermatology, urology and other specialties stacked on two floors. Mount Sinai South Nassau, the system's Oceanside hospital, anchors the county to the south, and a four-story multispecialty center opened in Wantagh last year. Put the pieces together and a pattern shows: the health systems that once expected Nassau patients to come to them are now building where the patients already are, on the roads they already drive.

For Carle Place itself, a hamlet of about a square mile that already absorbs the traffic of Roosevelt Field and the Old Country Road retail strip, a surgery center is a quieter neighbor than another big-box store, and a more useful one.

What it means if you live here

The practical change is simple. A resident of central Nassau who needs a routine outpatient procedure, a scope, a cataract repair, a spine injection, a foot surgery, has a new option that does not involve the Meadowbrook at 6 a.m. or a hospital campus parking garage. Surgery centers also tend to run on schedule in a way hospital operating rooms, which must absorb emergencies, cannot, so the 7:30 a.m. slot usually happens at 7:30 a.m.

The center opens this month. Details and physician information are at the center's own site, and scheduling runs through the referring surgeon's office, which is how ambulatory centers work: your doctor books the room, and the room is now 20 minutes away instead of 40.
