Greenwich-based Orthopaedic & Neurosurgery Specialists plans Westchester expansion
Orthopaedic & Neurosurgery Specialists PC, a practice of 24 specialized physicians based in Greenwich, will open its first Westchester office in September.
ONS signed an 11-year lease for 15,425 square feet at 500 Mamaroneck Ave. in Harrison, a building owned by Empire State Realty Trust.
The practice will invest $2 million to build out the office to include 14 exam rooms, digital X-ray and ultrasound space and a physical therapy center.
Sally Frank, chief operating officer of ONS, said the Mamaroneck office will be modeled after the group”™s other satellite space in Stamford. ONS opened at 5 High Ridge Park in 2015 and has already expanded its 16,000-square-foot space with a 3,200-square-foot physical therapy section that opens this month.
The practice”™s main location is a 35,000-square-foot building at 6 Greenwich Office Park.
Frank described the practice, which launched in 1998, as specialized with the “elite of the elite” physicians, recruited from medical schools and fellowship programs such as the Hospital for Special Surgery, NYU, Columbia University, Mayo Clinic and Yale University.
The practice”™s physicians are specialized in orthopedics, sports medicine, neurosurgery and physiatry, a nonoperative field of treatment orthopedic and spinal conditions.
“The model of the practice is to be subspecialized,” Frank said. “So we have doctors who are fellowship trained in the hand and wrist, foot and ankle, shoulder and elbow, joint replacement and of course spine.”
The group takes a conservative approach, Frank said, with about 10 percent of patients requiring surgery.
About 30 percent of ONS patients already come from Westchester, Frank said. The move to the county allows the group to continue to make room for the New York patients.
Frank described the Mamaroneck Avenue location as an ideal spot between Interstate 95 and the Hutchinson River Parkway.
“Obviously it”™s very easy access for our patients both north and south of that area,” Frank said.
ONS employs about 162 people total, outside of physicians, as physical therapists, physician assistants, medical assistants and other staff.
The practice expects to have six “anchor physicians” at the Westchester location, with an additional six physical therapists and 25 total staff.
All ONS physicians and licensed clinical staff have to be licensed in both New York and Connecticut, Frank said, a process that the practice started working toward last fall.
ONS expects to open in Harrison on Sept. 5.
