"I’m in an area where practitioners are established and have worked their territories for 20-plus years, so I needed to stake out my own territory. I did it through Facebook, where I reconnected with people from high school and college. My posts mix up personal and business details that give people a peek into my life and make me real and knowable, not just a name. I’ve become their real estate go-to girl, and Facebook has become a steady source of referrals."
