Withers Bergman LLP, which limits its clientele to wealthy folk, their wealthy families and advisors, has moved into its new 10th-floor, 8,500-sf headquarters at 430 Park Ave. The entire building recently underwent a full renovation, and Withers Bergman built out its space to reflect the firm's exclusive, old-money image.

Cushman & Wakefield senior director Barry Zeller and executive director Jonathan Serko represented the law firm while C&W's August DiRenzo, John Isaacs and Howard Nottingham negotiated on behalf of building owner 430 Park Ave. LLP. Terms of the lease have not been disclosed, but recent deals in the 19-story building closed in the high $60s.

"This was the perfect opportunity for Withers Bergman to reaffirm its position as the world's leading private client law firm," said Mr. Zeller. "The build-out was designed to mirror Wither's offices in London, creating a consistency of image essential to a global firm."
