Gerson Lehrman Group Expands Presence at One Grand Central Place with 18,230-Square-Foot Lease Extension
Empire State Realty Trust, Inc. (NYSE: ESRT) has announced the expansion of Gerson Lehrman Group, Inc. (GLG), a leading financial and global information services consulting company, at One Grand Central Place in Midtown Manhattan. The new 18,230-square-foot lease increases GLG’s total footprint in the building to an impressive 95,612 square feet, underscoring the company’s continued commitment to its New York City headquarters and its long-standing relationship with ESRT.
GLG renewed its 77,382-square-foot lease earlier in April 2025 and has now expanded further within the landmark property. The company, which joined the ESRT portfolio in 2013, occupies two full floors overlooking Vanderbilt Plaza — one of Midtown’s most dynamic and revitalized business corridors. This expansion not only strengthens GLG’s presence in New York but also reaffirms One Grand Central Place as a destination for premier global firms seeking top-tier office environments.
One Grand Central Place stands as one of ESRT’s flagship properties, combining classic Manhattan architecture with modern infrastructure and amenities. The 55-story tower provides fully modernized, amenitized office spaces that cater to the evolving needs of today’s workforce. Its prime location near some of New York City’s best dining, entertainment, and lodging options makes it a preferred choice among blue-chip tenants and forward-thinking organizations.
Among the newest additions enhancing the building’s amenities is SORA, an upcoming culinary destination featuring five highly curated Japanese chef-driven dining concepts, as well as a distinctive “direct-from-Tokyo cocktail experience.” The announcement of SORA further enriches the tenant experience, positioning One Grand Central Place as a hub for both productivity and lifestyle appeal.
The building’s unmatched connectivity is another major draw for tenants like GLG. One Grand Central Place offers direct in-building access to Grand Central Terminal, providing connections to commuter rail services, five major subway lines, and the Grand Central Madison concourse with access to the Long Island Rail Road (LIRR). This seamless accessibility supports employee commutes and client engagement, a key factor for global firms with diverse teams and clientele.
“GLG’s long-term tenancy at One Grand Central Place reflects the building’s unmatched location, premier amenities, and exceptional service,” said Ryan Kass, Executive Vice President, Co-Head of Real Estate, and Chief Revenue Officer at Empire State Realty Trust. “We are thrilled to continue our partnership and to provide GLG with a custom office space where the company can grow and thrive.”
GLG’s decision to expand highlights its confidence in ESRT’s property management and commitment to maintaining best-in-class office environments. ESRT’s approach to tenant experience combines sustainability, technology, and comfort — aligning with the needs of global companies focused on collaboration and innovation. The Trust’s properties are known for their modern infrastructure, energy-efficient systems, and hospitality-inspired design, which together create a healthy and productive workspace.
This latest expansion adds to ESRT’s track record of successful leasing activity across its Manhattan portfolio. One Grand Central Place, in particular, continues to attract and retain top-tier tenants from a range of industries, including finance, technology, law, and professional services. Its strategic location near Grand Central Terminal and proximity to Bryant Park, the New York Public Library, and Fifth Avenue shopping make it one of the most coveted office addresses in the city.
In the lease negotiations, GLG was represented by TJ Hochanadel, Robert Martin, and Dan Santagata of JLL, while the landlord, Empire State Realty Trust, was represented by Jordan Berger, Shanae Ursini, and Kerry Lavelle of ESRT, alongside Scott Klau, William Cohen, Erik Harris, and Neil Rubin of Newmark. The collaborative effort between these leading real estate professionals ensured a smooth transaction that aligned with GLG’s space needs and ESRT’s long-term leasing strategy.
Empire State Realty Trust continues to lead in offering high-performance office spaces designed for modern business operations. The company’s portfolio emphasizes sustainability, wellness, and convenience, supported by initiatives such as 100% carbon-neutral operations across its commercial portfolio and continuous investment in building modernization. These features have positioned ESRT as one of the most forward-looking real estate investment trusts in the United States.
For GLG, the expansion at One Grand Central Place represents more than just additional office space—it symbolizes growth, innovation, and a long-standing partnership built on trust and shared values. The company’s continued presence in ESRT’s portfolio reinforces Midtown Manhattan’s role as a global center for business and professional services.
As the demand for flexible, high-quality office environments continues to rise, Empire State Realty Trust’s properties remain a benchmark for excellence in the New York commercial real estate market. The GLG expansion is yet another testament to the strength and appeal of ESRT’s assets, reflecting the enduring value of well-located, well-managed office space in the heart of one of the world’s most vibrant cities.
Through this new agreement, both Empire State Realty Trust and Gerson Lehrman Group reaffirm their commitment to long-term collaboration, workplace excellence, and the continued vitality of New York City’s commercial real estate landscape.
