After studies at the Museum School in Boston and a degree in film from NYU's Tisch School, Marion started her film career on PBS specials and NOVA episodes in New York. Her stint on the Frontline show “Who Killed Adam Mann,” a Columbia-Dupont award-winning film on fatal child abuse, convinced her it was time to leave the city. Several moves later (including summers at the International Film and Television Workshops) Marion settled in Vermont to stay.
Marion was able to satisfy her passion for the outdoors specializing in shooting and editing action sports like skiing, snowboarding, running and mountain biking for network broadcast and commercials airing on PBS, NBC, CBS, ESPN, History Channel, Oxygen and Spike TV. She created Madmotion, LLC. to provided video services for a wide variety of broadcast and non-broadcast clients including Blue Cross and Blue Shield, the PBS series Birdwatch, The Vermont Department of Tourism, Vermont Ski Areas Association, The Vermont Lottery, Killingon and Okemo Resorts, Farm & Wilderness Foundation and The American Lighting Association while continuing her broadcast sports work.
In 2011, after experiencing first hand the effects of Hurricane Irene, Marion created the hour-long documentary "Flood Bound," an intimate portrayal of small-town life in Vermont and the powerful reaction to the devastation caused by that hurricane. The film aired on PBS.
In 2015 Marion developed and launched the "Spartan Up" podcast and YouTube series with the Spartan founder and CEO Joe De Sena. Her team (Joe De Sena, Sefra the Seedhuntress, Col. Time Nye and Johnny Waite) has interviewed over 300 guests including Richard Branson, authors Steven Pressfield, Gary Vaynerchuk and Tim Ferris, adventurer Sir Ran Fiennes as well as professors, fighters, CEOs. The show now boasts over 25 million downloads and views and is in the top 5% of all podcasts.
In 2019 Marion founded Interview Lessons to share her knowledge with podcasters and filmmakers.
