David Jón Fuller was born and raised in Winnipeg, Manitoba, and also lived for a year growing up in Edmonton, Alberta.
He studied at the University of Winnipeg, specializing in acting, and graduated with a B.A. (Hon). in Theatre in 1995.
He regularly appeared in Winnipeg Fringe Theatre Festival plays and other local productions in the 1990s, including a turn as the lead in Shakespeare’s Henry V for the Winnipeg Shakespeare Company in 1993. He performed at the Fringe in 1992 (Change of Face, which he co-wrote), 1994 (as Hotspur in Shakespeare’s Henry IV, Pt. 1), 1995 (in Unloveable You, by Dennis Trochim, which was held over for Best of the Fringe; and made a cameo in Elevator, by Florence Gibson, also held over), and in 1998 (in Tumblin’ Dice by Bob Hume, also held over).

He made his professional debut in Theatre Projects Manitoba’s Short Shots (1998) performing work by Ian Ross, Laurie Block, Margaret Pople, and Angus Kohm.
Aside from his work in English, he also performed in Icelandic with Stúdentaleikhúsið over two years when he lived and studied Icelandic language, literature, and history in Iceland, including two plays, and annual collections of comedic skits staged at Háskólabío (one of which was attended by then-president of Iceland Ólafur Ragnar Grímsson).
Fuller transitioned to a career in writing and editing, beginning as a proofreader at theatre and drama press Blizzard Publishing, then continuing as a copy editor, designer and eventually managing editor of Icelandic ethnic newspaper Lögberg-Heimskringla, and doing freelance writing for numerous publications.
He has worked as a copy editor for the Winnipeg Free Press since 2007. In 2013 the American Copy Editing Society awarded him third place for online headline writing, and again in 2014, for headlines he wrote for the Free Press.
His ability to turn a phrase also won him a free trip to Washington, D.C., when he came up with a new slogan for Canada for an NPR contest that was actually aimed at Americans, but the judges at New York City’s Studio 360 program nevertheless awarded him an all-expenses-paid vacation to the U.S. capital in 2012 for his slogan “Canada: Not Just Colder, Cooler.”
Never far from his theatre roots, he has also written features on and reviews of local stage productions for Uptown magazine in the early 2000s, most recently reviewing Fringe shows for the Free Press in 2024.
In addition to his non-fiction, Fuller’s published work includes numerous genre short stories in anthologies such as Carpe Noctem (Tyche Books, 2024); Leadership Gone Right (Farthest Star Publishing, 2024); War of the Words Anthology Vol. 1 (Alexandra Writers’ Centre, 2024); Parallel Prairies: Stories of Manitoba Speculative Fiction (Great Plains, 2018); Tesseracts 18: Wrestling With Gods (EDGE Publishing, 2015), Kneeling in the Silver Light: Stories From the Great War (The Alchemy Press, 2014); Long Hidden: Speculative Fiction From the Margins of History (Crossed Genres Publications, 2014); Accessing the Future (The Future Fire, 2015); and in French translation in Ténèbres 2017.
His work has also appeared in On Spec magazine and on the Far Fetched Fables fiction podcast.
His flash fiction piece “It’s Fenrir, You Morons” received an Honourable Mention in 2024’s War of the Words competition at Calgary’s When Words Collide.
He lives in Winnipeg.
