Atria Health Institute to open at One High Line with brokerage by Access Real Estate

Manhattan, NY Access Real Estate, a U.S.-based investment group with a diverse portfolio of world-class properties, and Witkoff, a privately held real estate investment and development firm, has leased Atria Health Institute the full commercial space at One High Line, the mixed-use development in thrWest Chelsea neighborhood.

Co-founded by Alan Tisch and David Saltzman in 2020, Atria Health Institute is a membership-based preventive health care practice focused on proactive, prevention-first medicine through highly personalized, team-based care. Atria will occupy One High Line’s full five-story commercial component, a highly visible space that connects the development’s East and West towers and spans approximately 52,000 s/f. The facility is expected to open in 2027, becoming Atria’s second New York Institute. Its first, a 57,000 s/f flagship at 432 Park Ave., opened in 2022.

“Our membership in the New York area continues to grow, and One High Line presents the space and scale to deliver the proactive, preventive, and personalized care that Atria was built on — for our members here and for the patients who travel to New York from around the world seeking the highest standard of care” said Alan Tisch, CEO and Co-Founder of Atria Health and Research Institute. “We founded Atria on the belief that health should be preserved, disease should be prevented, and longevity should be enhanced—all by design. This new location allows us to expand on that vision and bring it to even more people.”

“One High Line was designed to bring together exceptional residential, hospitality, and lifestyle experiences in one of Manhattan’s most dynamic neighborhoods,” said Jonah Sonnenborn, Senior managing director of Access Industries and head of Access Real Estate. “Atria represents exactly the kind of forward-thinking, medically rigorous institution we envisioned for this space. Their commitment to innovation, longevity, and personalization in preventive care reinforces One High Line’s position as a premier destination in West Chelsea.”

Built around a coordinated, multidisciplinary care model, Atria combines advanced diagnostics, on-site imaging and testing, and individualized care plans across more than 15 medical specialties, including cardiology, endocrinology, metabolic health, brain health, pediatrics, women’s health, medical dermatology, exercise physiology, nutrition, and longevity. Membership includes access to services such as 3T whole-body MRI, 3D mammography, DEXA, single-photon-counting CT scans, EKG, ultrasound imaging, and 24/7 home care for urgent and routine medical needs. Atria currently operates locations on 57^th St. in New York City and in Palm Beach, Florida, with a location in Los Angeles opening in July 2026, in the Bay Area in 2027, and in Miami in 2028.

“The alignment between Atria and One High Line was very natural,” said Alex Witkoff, CEO of Witkoff Group. “One High Line has continually set the pace for New York’s luxury residential market, bringing together world-class design, ambition, and lifestyle offerings. Atria’s vision for highly personalized, forward-thinking preventive care makes them an ideal presence in this community.”

Designed by Bjarke Ingels Group, One High Line spans a full city block along High Line Park. The development comprises two sculptural travertine towers overlooking the Hudson River. The 36-story West Tower features interiors by Gabellini Sheppard. The 26-story East Tower features interiors by Gilles & Boissier.

One High Line includes 236 residences with unobstructed views of the Hudson River and the New York City skyline. Since launch, the development has surpassed $1.1 billion in closed condominium sales, underscoring continued demand and strong sales momentum. Residents have access to 18,000 square feet of private amenities, including a 75-foot lap pool with cabanas, a fitness center with spa facilities, a glass-enclosed double-height bridge lounge, a golf simulator, a virtual gaming studio, and private dining spaces with a catering kitchen. The development is also home to Faena New York, marking the iconic hotel brand’s first location in New York City and bringing its signature hospitality, cultural energy, and global cachet to West Chelsea.
