Four prominent corporate partners from Reed Smith are peeling off for Cooley’s offices in New York and San Francisco.

Yvan-Claude Pierre, the chair of Reed Smith’s U.S. capital markets practice and head of the firm’s global corporate and securities group, is leaving the firm with fellow New York-based partners Daniel Goldberg and William Haddad. Garth Osterman, another Reed Smith corporate partner in San Francisco, is also making the move.
