SAN FRANCISCO — Sometimes, when you finally get the chance to work with a competitor, you realize they actually have a lot to offer. That’s what attorney Michael Mallow says led his six-lawyer consumer class action defense team to join Sidley Austin’s Los Angeles office last week from Loeb & Loeb.

The group includes partner Mark Campbell in Los Angeles and Livia Kiser in Chicago, as well as three Los Angeles associates, whose names have not yet been announced.
