Summary
Kohlberg, a prominent private equity firm managing $17 billion in assets under management with a specialized focus on healthcare company investments, has signed a lease to relocate its New York City headquarters within Midtown East. The firm will occupy the entire ninth floor of 500 Park Avenue, a SL Green Realty-owned office tower located at the corner of Park Avenue and East 59th Street. The space totals 18,820 square feet and represents a full-floor occupancy.
The move constitutes a relocation rather than a new market entry, as Kohlberg currently maintains offices on the 12th floor of Marx Realty's 545 Madison Avenue, approximately five blocks away. JLL's Paul Glickman and Kristen Morgan, who represented Kohlberg in the transaction, noted that the firm was attracted to the property's "unmatched combination of location, architectural distinction, and the existing transformation underway," emphasizing that a full-floor corner opportunity aligned with Kohlberg's desire for "best-in-class" office environments. SL Green was represented by a separate JLL team comprising Frank Doyle, Cynthia Wasserberger, and Michael Pallas.
The landlord had been marketing 500 Park Avenue at $120 per square foot as of November 2025, though the final rental rate and lease term were not disclosed in the announcement. The transaction adds to the building's growing roster of institutional and luxury tenants. Other recent signings include divorce litigation firm Rottenstreich Farley Bronstein Fisher Potter Hodas, which leased the entire eighth floor (also 18,820 square feet) in November, Tom Ford Fashion, which secured a 10-year lease for an 11,118-square-foot headquarters on the sixth floor in June 2025, and Vera Wang, which leased 26,708 square feet spanning the fifth floor and part of the seventh floor in August 2023. The building's tenant mix reflects the property's appeal to both financial services and luxury retail sectors.
