Tria Thalman
Executive Producer for Natural History, Smithsonian Networks
I am one of the lucky ones… someone who knew early on what she wanted to do for a career and I’vebeen enjoying doing just that for 25 years. In my current role, I help develop and creatively oversee a broad slate of wildlife films for Smithsonian Channel and our international networks. I love working with production companies to help shape their films and am happy to get deep in the weeds with scriptwriting if needed. But, a producer at heart, I’m happiest when I’m in the field. Before joining Smithsonian Channel I worked as a freelance producer, creating films for National Geographic, Discovery, Nat Geo Wild and Animal Planet. I have a bachelor and a masters degree in zoology from the University of Cambridge and then studied film at the University of Bristol before moving to the United States.
