In 2011, Prokop was represented by Management 360 and
APA. His first acting job was a brief appearance on
Hannah Montana in 2007, followed by a walk-on role on
The Office. He guest starred on
Medium (2009) as Kyle "K.C." Covington for one episode. Prokop landed a role in
Furry Vengeance (2010), playing Tyler Sanders, the son of Dan Sanders (
Brendan Fraser), and he played the role of Josh Rosen in the Disney Channel's
Geek Charming (2011), based on author Robin Palmer's novel. In 2012, he appeared in an episode of
Modern Family, opposite then girlfriend and series regular
Sarah Hyland. His last acting credit was in the 2013 film
April Apocalypse, with his last three film roles being in films starring Hyland. He was also a producer of the 2015 film
See You in Valhalla, which also starred Hyland and was produced before she broke up with Prokop. However, Prokop was legally disallowed from attending the film's premiere due to Hyland's protection order against him that took effect six months before the film's release (described further below). ==Personal life and legal issues==
