Since the Baltimore-founded Am Law 100 firm Venable opened its San Francisco office in 2013, the firm's local practice has grown nearly sixfold, to 31 lawyers and 19 staff. In December, Venable relocated to a larger space for the third time as part of its ongoing expansion on the West Coast. On Thursday, The Recorder took a tour as Venable celebrated the opening of the new office at 101 California Street in the Financial District.   "We really wouldn't have been where we are without the support locally from the city's involvement and the opportunities this region presents," said James Nelson, partner-in-charge of Venable's San Francisco office, in his remarks. Thursday's event also featured San Francisco Mayor Mark Farrell, a former associate at Wilson Sonsini Goodrich & Rosati, who congratulated Venable on its growth in the city. "I would want to be a client here, I would want to be an attorney here as well," said Farrell, complimenting the view from the new space. "Thank you for investing in our city as a law firm. Thank you to all the clients who are here that are investing your talents and your time to the city of San Francisco."
