McDermott Will & Emery has hired William “Bill” Donovan, Jr., who most recently served the head of Cooley’s Los Angeles litigation practice, to bolster its West Coast class action and complex commercial litigation capabilities.

Donovan officially joined McDermott’s litigation practice group in Los Angeles on Friday. Before moving over to Cooley in 2014, Donovan spent nearly 12 years at DLA Piper’s Los Angeles office.
