Best known as being one of the daughters featured on NBC's 2003 summer hit reality series "Who Wants to Marry My Dad?" Mueller was the opinionated daughter of Don who put his trust in his four kids to choose a wife for him. Through outrageous secret tasks, surprising revelations about each player's past and "lie-detector" tests, Heidi and her siblings chose Don's fiancée. Born and raised in Cincinnati, Ohio, Mueller relocated to Los Angeles to embark upon her acting career with "Passions." Though "Passions" is her first contract television role, Heidi has appeared in numerous television commercials including one for Crest White Strips.

Mueller loves Los Angeles but travels back to Cincinnati quite frequently to visit with her close knit family which also includes her other siblings, Chris, Joey and Karla and her mother and step-father, Pam and Jeff Hill. Her birthday is January 29.
