His father was an actor and writer of locally premiering plays, and his mother was a director and photographer.
As his older brother, actor Max Kasch, began to experience success, the brothers competed for jobs; their success caused the entire Kasch family to leave Ojai and move to the more favorably located Camarillo.
[citation needed] Kasch portrayed a Texan high school student in the Noggin comedy-drama series Out There.
After a brief absence from the series, he returned in the third and seventh seasons as Gabrielle Solis' secret admirer.
