Sean began making films in elementary school with a home video camera, practicing his videography and editing skills as he realized his passion for film. By high school, he was pursuing work professionally on movie sets in New York to gain experience in the field. He enrolled at Northampton Community College to gain a formal education in Television and Radio. After graduation, he launched his first production company, [K] Studios, with a business partner and served corporate clients including The Martin Guitar Company, MTV Books, Empire Beauty School, Bravo (TV), Service Electric/Blue Ridge Cable TV, Majestic Athletic, The MLB Network, The Collegiate Empowerment Company, and The Weller Health Education Center. The Eastern Pennsylvania Business Journal named Tiedeman in the top 20 of the region's business leaders under the age of 40.
Sean directed his first horror-comedy Hell's Half Acre in 2006. The film launched to rave reviews, including coverage in Fangoria magazine and has quickly developed a large cult following. Synergy Magazine in Australia praised "Hell’s Half Acre ends up packing quite a punch in both the horror and dark humor departments and stands out from many other indie productions." And in 2015 HorrorNews.net stated “Hell's Half Acre delivers over and over again. This is one of those hidden gems that I love finding in this job...”
After co-directing and editing The Stage for nearly ten years, an award-winning music television program featuring interviews with high profile musicians and celebrity guests, Sean found his heart in documentaries. He filmed segments for The 100 Scariest Movie Moments (Bravo TV) and began producing DVD/Blu-ray bonus features for films like Bereavement starring Michael Biehn and Alexandra Daddario.
Recently, Sean successfully raised $47,684 on Kickstarter for his first full-length feature documentary The King of Arcades. Co-produced by Adam F. Goldberg, creator of The Goldbergs on ABC, the nostalgic film has met with great success. The King of Arcades premiered to a sold out crowd at The Sands Casino Resort (Frank Banko Alehouse) in Bethlehem, Pennsylvania and appeared on several critics' top five lists of the best video game documentaries. The DVD was released on Amazon and the digital download was available exclusively via GOG.com.
Sean met his wife and co-producer, Krystle-Dawn, on the set of Brutal Massacre: A Comedy. They were happily married in a movie theater. In his spare time, Sean enjoys playing with his son Liam, as well as coaching the Yankees for Miracle League of the Lehigh Valley. Sean continues to live his dream: working full-time on all aspects of production, independent films, TV, and documentaries.
