Very little is known about Ellingson's personal life. Early in his career, he worked minor roles on the sets of a few low-grade feature films. He then became a special effects coordinator for the horror anthology series Freddy's Nightmares, based on the A Nightmare on Elm Street franchise. He also guest-starred in one episode of Freddy's Nightmares, and went on to play a minor role in A Nightmare on Elm Street 5: The Dream Child. Ellingson has since coordinated the special effects for a number of TV shows, low-grade feature films, and made-for-TV movies. His most recent, well-known, and prolific work was on the CBS-produced police procedural series Criminal Minds, which he also occasionally acted in.
On Criminal MindsEdit
Ellingson has served as the show's longtime special effects coordinator. In addition, he portrayed a police officer in the Season Four episode Brothers in Arms, a van driver in the Season Seven episode Dorado Falls, and a trapped volunteer in the Season Twelve episode Elliott's Pond.
