The 17,400 s/f condominium unit was purchased from Sloan-Kettering Institute for Cancer Research. The site of the new building was originally sold to Sloan-Kettering by St. Catherine's subject to St. Catherine's right to buy back the church unit. "This was an excellent opportunity for St. Catherine's and Sloan-Kettering to work together to expand both of their facilities," said Marshall Cohen, who worked on the deal for Cohen & Perfetto. Cohen, a partner at Cohen & Perfetto, and Stefanie Marazzi, an associate attorney, represented St. Catherine of Siena.
