He is the consulting director on My Little Pony Equestria Girls: Friendship Games. Thiessen has also directed My Little Pony Equestria Girls and the Friendship Games animated shorts and co-directed My Little Pony Equestria Girls: Rainbow Rocks and its animated shorts.
He is the consulting director of the second half of season five of Friendship is Magic, beginning with Canterlot Boutique. Thiessen is also currently directing the original series' upcoming feature film for 2017.
During the conception phase for the series in 2010, show creator Lauren Faust and Hasbro signed Studio B Productions (later renamed to DHX Media) to animate, and Studio B pitched Thiessen to be supervising director, which Faust agreed with. Thiessen's initial reaction to the position was "brace for girly overload", but he became excited once he saw Faust's development materials.
When Faust departed from the show in 2011, Thiessen assumed the role of showrunner for season two of Friendship is Magic in her place.
For his work on the series, Thiessen was nominated for "Best Direction in an Animation Program or Series" for Friendship is Magic season one episode, Party of One, at the 2012 Leo Awards.
Thiessen's professional credits include being assistant director and co-director for Disney's Pucca, for which he was also nominated for a Leo Award in 2006; a storyboard artist for Cartoon Network's Ed, Edd n Eddy; a graphics designer and supervising animator for Aaagh! It's the Mr. Hell Show!; and animation director for George of the Jungle.
