Jonathan gave serious thought to an acting career following a family visit to Universal Studios Hollywood in 1991. His parents decided to let their sons try their luck in acting for 6 months, and so Jonathan and Richard moved down to Los Angeles with their mother while their father stayed back in Washington with Candice. Soon after, Jonathan landed a Corn Pops commercial.

He also made two TV movies, The Legend of the Ruby Silver (1996) and The Prisoner of Zenda, Inc.

In 1998, he filmed several episodes for the ABC series Boy Meets World (1993). In 1999, he again took a short break from GH to film a supporting role in the independent film True Rights (2000).
