Montefiore Health System and Amazon One Medical announced on June 9, 2026, the opening of a co-located primary care office at Montefiore Einstein Advanced Care (MEAC) in Westchester — the first time Amazon One Medical has embedded a brick-and-mortar primary care clinic inside a New York specialty care facility. The new office, located at 555 Taxter Road in Elmsford, opens within a campus that handled approximately 91,000 patient visits in 2025 and offers a direct bridge between Amazon's technology-enabled care model and Montefiore's academic specialty network.What Happened
The MEAC Westchester location spans 186,000 square feet and houses nationally recognized programs including a Comprehensive Brain Center and an Asthma, Allergy, and Sinus Center. The newly embedded Amazon One Medical office operates four exam rooms staffed by two primary care providers, offering same and next-day appointments, on-site laboratory services, preventive screenings, chronic condition management, and care for acute concerns — for both pediatric and adult patients.
- Amazon One Medical opens its first co-located primary care office inside a Montefiore specialty facility in Westchester, New York.
- The MEAC Westchester campus logged roughly 91,000 patient visits in 2025 across its 186,000-square-foot facility.
- A second Westchester location is planned before year-end, adding to 15 existing Manhattan specialty access points.
The move marks the latest step in a partnership that began with a January 2025 announcement of coordinated primary and specialty care access in New York. An expanded agreement took effect January 1, 2026, designating Montefiore as Amazon One Medical's clinically integrated specialty care partner across 15 Manhattan locations, including facilities at Hudson Yards, the Hutchinson Campus, and Riverdale. Westchester integration, piloted through an Upper West Side location launched in spring 2025, has now produced a deeper co-location model.
Strategic Context
For Amazon (AMZN), the Montefiore alignment advances a core strategic priority: converting One Medical's hybrid virtual and in-person platform into a full-spectrum care ecosystem. Amazon One Medical currently partners with more than 10,000 employers nationwide. By embedding inside a high-volume specialty hub, the company gains immediate access to a referral pipeline and a patient base that already navigates complex, multi-specialty needs.
For Montefiore, which serves approximately three million patients across the Bronx, Westchester, and the Hudson Valley, the partnership addresses a persistent gap in primary care density. The Westchester market, increasingly competitive for outpatient volume, benefits from One Medical's same-day availability and 24/7 virtual care capabilities — features that complement Montefiore's hospital-anchored model but have historically not been its core offering.
"Having Amazon One Medical's first co-located location ensures academic medicine meets care where and how people want it," said Peter P. Semczuk, DDS, MPH, a senior vice president at Montefiore Einstein. Lindsay Sher, M.D., added that the co-located model is designed to reduce friction by consolidating primary and specialty access under one roof.
AI and Technology Angle
Amazon One Medical's platform gives patients access to on-demand video visits, secure provider messaging, digital triage assessments via the One Medical app, and proactive prescription renewal and referral reminders. Integrated with Montefiore's specialist network, the model is designed to move patients from primary care to specialty appointment — and, where required, direct hospital admission to Montefiore facilities — without the coordination gaps that characterize conventional referral pathways. The co-location at MEAC is the clearest expression yet of Amazon's bet that tightly linking primary and specialty care digitally and physically will differentiate it in the employer benefits market.What Comes Next
Montefiore and Amazon One Medical have confirmed plans for a second Westchester location before the end of 2026. The partners have not disclosed financial terms of the arrangement. As Amazon scales One Medical's footprint in employer-dense suburban markets, the Westchester model — co-located inside a high-traffic specialty campus — is positioned as a replicable template for future expansions.
Outlook
The June 2026 MEAC opening consolidates an Amazon One Medical–Montefiore healthcare partnership that has evolved from a coordination agreement to full physical integration in just 17 months. With a second Westchester site planned and 15 Manhattan specialty access points already active, the partnership represents one of the most structurally integrated primary care arrangements Amazon has built outside its own standalone clinics. Execution at scale — sustaining same-day access and care coordination quality as volume grows — will determine whether the model delivers on its promise of reducing fragmentation in one of the country's most complex regional health markets.
