Labor and employment giant Littler Mendelson has brought on Crowell & Moring partner Mark Romeo as a shareholder in its Irvine office.

Romeo, who practiced at Littler as an associate in his early career, returned to the San Francisco-headquartered firm Monday. His practice focuses on restrictive covenants, trade secrets and unfair competition litigation. Romeo said he was attracted to the broader reach of Littler’s platform.
