Main Campus Transformation

HSS is the world's leading academic medical center dedicated to musculoskeletal health, ranked No. 1 in orthopedics worldwide by Newsweek, and No. 1 in orthopedics in the United States for the past 11 consecutive years by U.S. News & World Report.

To continue to meet growing demand for our unmatched care, HSS is investing in new facilities and enhancement to our Upper East Side campus, as well as in beautifying the neighborhood. At the heart of this plan is construction of the Anna-Maria and Stephen Kellen Tower (rendering above). Rising 12 stories over the FDR Drive, this new, 94,000-square-foot clinical building will adjoin our current Main Hospital facility. The tower is made possible with more than $130 million in early philanthropic support from HSS donors, including a lead gift from the Anna-Maria and Stephen Kellen Foundation.

Construction is expected to begin in fall 2021. Check back here for updates on our progress.

The Anna-Maria and Stephen Kellen Tower

The HSS Kellen Tower will expand care for joint replacement and spine conditions with three private inpatient floors, physician offices and exam rooms, and on-site imaging to support our high-quality musculoskeletal care. The added capacity created by these new inpatient units and renovation of recovery floors in the main hospital will allow HSS to convert from 30 to 70 percent private patient rooms across the main campus, an institutional priority underscored by the pandemic and necessary to optimizing the healing environment for our patients.

East River Esplanade Renovation

Included in the plan for the HSS Kellen Tower construction and as part of our commitment to the community, HSS is making critically needed improvements to the East River Esplanade from 72nd to 78th Streets. This work will reflect the New York City Department of Parks and Recreation’s master plan for the Esplanade, and builds on our previous investment of $1.8 million to renovate the Esplanade from 70th to 72nd Streets in 2018.

About the Transformative Gift from the Anna-Maria and Stephen Kellen Foundation

The Anna-Maria and Stephen Kellen Foundation provided a transformational $35 million gift to enable construction and name this state-of-the-art medical facility. The gift builds on the Foundation’s long history of support for HSS and honors the legacy of Anna-Maria and Stephen Kellen. “We were inspired by all the lives that will be changed in this new building,” said Marina Kellen French, Vice President of the Foundation and an HSS Trustee. “It is not just about bricks and mortar; it’s about helping people and New York City.”

 

Project Q&A

What will be housed in the HSS Kellen Tower?
The HSS Kellen Tower will expand care for joint replacement and spine conditions and include three inpatient units with private rooms, a dedicated imaging center, and physician offices and exam rooms.

When will construction begin and when will the HSS Kellen Tower open?
We plan to break ground in fall 2021 and open the building in 2024.

How will the HSS Kellen Tower impact the current HSS campus?
The HSS Kellen Tower will facilitate the conversion to mostly private rooms across the HSS main campus. It will also enable an increase in the number of operating rooms in the Main Hospital. The HSS Kellen Tower will be accessible to the public via sky bridge from the Main Hospital as well as from the adjacent Ambulatory Pavilion on several floors.

What is the timeline for the East River Esplanade renovation?
Work on the East River Esplanade will begin in coordination with initiation of construction of the HSS Kellen Tower and will be phased in coordination with the appropriate city agencies as well as the overall timeline of the project construction.

Will the Esplanade need to close during renovation?
Upon start of construction, a portion of the Esplanade, from the midblock between East 70th and 71st Streets to East 72nd Street, will be closed for approximately six months. During this time, HSS will install a temporary ramp to provide access from the 71st Street walkway to the Esplanade south of 71st Street. Portions of the Esplanade will also be closed between 72nd and 78th Streets once the base of the tower is complete and Esplanade refurbishment begins.

Will portions of the FDR need to close during renovations?
There will be brief closures of the FDR Drive, in compliance with Department of Transportation guidelines. Closures will be timed to minimize disruption, and the community will be notified in advance.
