NEW YORK—Marketing guru Bob Lippman, 43, is also a getting-divorced guru, colleagues noted Tuesday. "Bob has an incredible knack for identifying branding strategies to connect with a demographic," coworker Ann Lamp said. "He's almost as good at establishing a product's core consumer message as he is at ending loveless, doomed marriages." In the past 10 years, Lamp has won four Mobius Awards and been married three times.
