He is best known for his roles as Jason in Young Hercules, Dennis McClaren in Patriot, and Eric McGowen in The Next Karate Kid.

Conrad spent a year studying at the Piven Theatre Workshop, then signed with an agent and moved to Los Angeles with his brother Steven, who was in the process of selling the script for Wrestling Ernest Hemingway.

He then taught high school and coached football but returned to Los Angeles in 2005 to pursue acting.

He has appeared in some of his brother's productions, including Patriot[2] and Perpetual Grace, LTD.[3] Conrad originally was cast as Adrian Chase / Vigilante for the streaming series Peacemaker, the first DC Extended Universe television show.

However, he left the series over creative differences after filming five-and-a-half episodes; director James Gunn recast the role with Freddie Stroma, reshooting or redubbing all of Conrad's scenes.
