Keith Middlebrook was born in Honolulu, Hawaii, to Floyd and Martha Middlebrook and is the youngest of three children. He lives and operates his companies out of Murrieta, California about an hour and fifteen minutes just outside of LA where he is a single dad raising his daughter while spending the other half of the time in LA. His first taste of Hollywood was a semi-scripted stint on Judge Judy when he then discovered he wanted to be an actor. Then years later a friend told him he could get him on The Sopranos as an extra so he flew to New York and then the passion to be an actor grew, which then led into many hours spent working on the Entourage set learning the business. He then landed his first role on Iron Man 2.
