Kendra and Sue talked with Kara Callahan, she’s the Marketing lead for the Harry Potter: The Exhibition which is coming to the Cambridgeside Galleria in September. Kara began her career cross-country promoting for the Ringling Bros and Barnum & Bailey Circus, Disney on Ice and The Radio City Rockettes – It’s clear that when a show is coming to town, Kara is probably the marketing master behind it.
