This Christmas season is a busy one for San Francisco based Lacey Quinn. Beyond the holidays, she has to work as Quinn + Whistler, the design company she co-owns and operates with her boyfriend, Roger Whistler, who she's known since grad school, has to make some last minute changes to its proposal for a major live/work housing development, which, if they sell the idea to the prospective clients, would set their firm up for years, and bring the brand Quinn + Whistler much needed cachet.
