Steve Ellmore is an American filmmaker, photojournalist, and veterans' activist. His experience behind the lens dates back to the 80s with his first 35mm camera. From there he migrated to TV and audio production before joining the U.S. Air Force in 1992. After retiring from the military in 2012, he picked up the camera again as a freelance photographer.

His venture into activism and filmmaking began with the American Taxpayer Relief Act of 2012 and the looming sequestration. At the time the U.S. government was considering a reduction in military benefits, including retirement pay, as a means for reducing the federal budget. Ellmore responded with the development of Allegiance to the Same, a documentary he conceived to raise awareness of the issue. A year later the project was shelved, thanks in part to the efforts of the veterans' groups he had worked with on the film.

In 2017 he began work on his next big project, a film about veterans starting a marijuana grow in the Midwest. The original idea was scrapped due to budgetary constraints, but not before convincing Ellmore of the effectiveness of treating PTSD with cannabis.

Initially a skeptic, his research into the therapeutic benefits of the plant convinced him there's a story worth telling. He immediately began production on the documentary Unprescribed, establishing Allegiance Films LLC in the process.

Ellmore is a Southern California native who now resides in Maryland. He received his bachelor's degree from the University of Maryland University College and his master's from Johns Hopkins University, both in communications.

His portfolio includes documentaries, short films, webcasts, and social media content.
