Mount Sinai Health System has opened a new outpatient surgical center in Carle Place, bringing operating rooms, procedure suites, and dozens of recovery bays to Old Country Road as part of a broader push to expand advanced surgical care across Long Island. The 20,400-square-foot Peakpoint Central Nassau Surgery Center, located at 371 Old Country Road, opened this month as a joint venture between Mount Sinai, local surgeons, and private ASC operator Merritt Healthcare.
According to Mount Sinai Health System, the new facility includes two operating rooms, two procedure rooms, 17 recovery bays, three private recovery bays, and three 23-hour stay rooms. The center is designed to handle both routine and complex procedures across gastroenterology, gynecology, ophthalmology, orthopedic and spine surgery, otolaryngology, pain management, plastic surgery, podiatry, and urology, and it will convene Mount Sinai's Long Island-based surgeons under one roof while also giving affiliated and non-affiliated physicians access to its facilities.
Mount Sinai urologist Michael A. Gorin, M.D., who serves as the center's medical director, said the facility will let Long Island patients receive ambulatory surgical care in a state-of-the-art setting, per the health system's announcement. New York State Department of Health records show that Central Nassau ASC LLC, doing business as Peakpoint Central Nassau Surgery Center, holds an active state operating license under Gorin's medical direction, valid through April 2028.
A Joint Venture Model Built for Suburban Expansion
Mount Sinai's partner on the project, Connecticut-based Merritt Healthcare, was founded in 2001 and works with more than 500 physicians, having developed 24 ambulatory surgical facilities nationwide, according to Newsday. The Carle Place opening follows a template the two organizations established in September 2024, when they opened the 25,106-square-foot Peakpoint Midtown West Surgery Center in Manhattan with four operating rooms and 12 recovery bays, launching the Peakpoint brand for their joint ambulatory ventures.
Ken Long, senior vice president of network operations for Mount Sinai Health System, said Peakpoint Central Nassau advances the system's delivery of care to Long Island patients, per Mount Sinai's announcement. Brent Stackhouse, managing director of Mount Sinai Ventures, said the center reflects a commitment to expanding outpatient access to advanced surgical treatments and medical care. Mount Sinai describes Peakpoint Central Nassau as connecting its existing facilities across Long Island, including care hubs in Wantagh and Greenlawn, as it works to bring high-quality clinical services closer to where patients live.
Why Health Systems Are Moving Surgery Out of Hospitals
The Carle Place center is part of a national shift of routine surgical volume away from hospital buildings and into standalone outpatient facilities, a trend Mount Sinai's own reporting has tied to insurance incentives and federal site-neutral payment policies aimed at aligning Medicare reimbursement across care settings. Medicare pays hospitals roughly 60% more than ambulatory surgery centers for identical outpatient procedures, according to Becker's ASC Review, a reimbursement gap that has pushed health systems and physician groups toward lower-cost joint-venture centers like this one.
Peakpoint Central Nassau will run standard outpatient hours from 7:30 a.m. to 4:30 p.m., Monday through Friday, structured for elective, non-emergency care rather than emergencies. The center requires every surgical patient to have a dedicated adult escort remain with them for 24 hours after their procedure and to avoid driving or major decisions during that window, safety protocols the center says are necessary since patients are discharged the same day without an overnight hospital stay.
Part of a Bigger Long Island Build-Out
The Carle Place opening lands amid a flurry of Mount Sinai investment across Nassau and Suffolk counties. In July 2025, the system opened a $70 million, 63,000-square-foot multispecialty clinical care facility in Wantagh, its fifth major outpatient hub on Long Island, bundling diagnostic and specialty care in one location. Mount Sinai South Nassau in Oceanside, the system's primary hospital anchor on Long Island, also opened a $50 million emergency department expansion this past March as part of its ongoing construction of the four-story Feil Family Pavilion, according to Becker's Hospital Review.
Mount Sinai South Nassau, formerly South Nassau Communities Hospital and founded in 1928, joined Mount Sinai Health System in December 2018, marking the health system's first hospital acquisition outside New York City and the start of its multi-year Long Island expansion. Hoodline previously reported on a $17.7M cardiac lab investment at the Oceanside hospital, part of the same regional push to meet rising patient demand.
Mount Sinai Health System describes itself as one of New York City's largest academic medical systems, with seven hospitals, more than 400 outpatient practices, over 9,000 physicians, and roughly 48,000 employees. The Mount Sinai Hospital ranks No. 5 on Newsweek's World's Best Hospitals list and No. 1 in New York, while the Icahn School of Medicine at Mount Sinai ranks No. 11 among U.S. medical schools and No. 1 among freestanding medical schools for National Institutes of Health funding, according to the health system.
