WilmerHale Welcomes Experienced Litigator to Los Angeles Office


Christopher T. Casamassima has joined WilmerHale’s Los Angeles office as a member of the Litigation/Controversy and Regulatory and Government Affairs Departments and the Business Trial and Antitrust and Competition Practice Groups.

Mr. Casamassima was previously at Kirkland & Ellis LLP in Los Angeles, where his practice focused on complex business disputes involving antitrust, breach of contract, fraud, business torts, trade secrets and other commercial issues.
