Jamie Tian, 25, has found a way to expand her market beyond its geographic limits. A fluent speaker of Mandarin Chinese, the world’s most widely spoken language, Tian works frequently with clients living abroad looking to relocate or purchase investment property in the Beverly Hills area. “When they come here, they want to meet someone who speaks their language,” she says. It also means she makes herself available for 4 a.m. Skype sessions, when needed, to accommodate the time difference. Tian’s other notable niche: working with developers to market environmentally friendly properties, for which she draws on the knowledge she gained studying environmental science at UCLA. In that vein, she enjoys giving back to green causes, which recently included a successful project to preserve the Sage Hill natural wildlife area at the edge of the UCLA campus.
