Manhattan, NY The Feil Organization has signed a 21,000 s/f, 15-year expansion and extension across the entire seventh floor at 551 Fifth Ave. with Sadis & Goldberg LLP, a leading financial and corporate law firm. The firm currently occupies the partial 16th and 21st floors, totaling 15,000 s/f. 

“Our long-standing relationship with Sadis & Goldberg is a testament to the enduring appeal and adaptability of 551 Fifth Ave.,” said Andrew Wiener, head of commercial leasing at the Feil Organization. “Their recommitment underscores their confidence in 551 Fifth Ave., and our ability to provide brand-new, customized space demonstrates our commitment to supporting their continued growth and success.”

“The new lease provides Sadis with approximately 50% more office space, symbolizing our long-term investment in our growth and continued larger presence in the marketplace,” said Yehuda Braunstein, partner at Sadis & Goldberg LLP. “We are in a growth mode and are very excited to be able to welcome more lateral partners and associates who seek long-term career stability and thrive in a team oriented culture. This expansion reflects our continued confidence in the building, its prime location and Feil’s ability to deliver a modern workspace that supports both our practice and long-term growth.”
