SAN FRANCISCO — Venable’s new San Francisco office is adding a commercial litigation partner from Arnold & Porter.

Angel Garganta represents financial institutions, manufacturers and service companies in unfair business practice, consumer class action and commercial disputes. At Venable, he’ll be joining commercial litigator Thomas Wallerstein, who came aboard when the office opened in October, office chairman James Nelson and corporate partners Arthur Cirulnick and Michelle Ontiveros Gross. Garganta’s move marks a split from his longtime colleague Trenton Norris. The duo joined McCutchen Doyle Brown & Enersen about a decade before it merged with Boston’s Bingham Dana in 2002. Then, in 2008, they moved with IP litigator Monty Agarwal to Arnold & Porter’s San Francisco office, which had opened three years prior. The three helped build out the NorCal post for the D.C.-based firm, Garganta said. Norris and Garganta have recently defended food companies sued over allegedly deceptive labels in so-called food court cases.

Venable’s San Francisco office, which is the home base for five partners, offers a chance to help build out an office, Garganta said. Additionally, “my kinds of cases are more of a central focus for Venable,” he said.

“If you look at the firm, you’ll see a huge focus on advertising law and consumer privacy. They also have a very strong FTC consumer practice. All of that ties in well with the type of consumer protection class action cases I defend,” he said. “I’m also interested in expanding my financial services practice.”

Correction: An earlier version of this story said Venable’s S.F. office was home to five lawyers. In fact, there are eight, including the five partners mentioned, two associates and an of counsel.
