Nancy McKeon's life began in Westbury, New York, on a Monday, specifically April 4, 1966, to loving parents Barbara and Don McKeon. At the tender age of two, she embarked on a modeling career, posing for Sears & Roebuck catalog advertisements featuring baby clothes. Her early start was merely the beginning, as she and her brother Philip went on to appear in an astonishing 65 commercials within a span of seven years.
As her brother Philip landed a role in the popular TV series Alice, which premiered in 1976, the McKeon family made the decision to relocate to Los Angeles. This pivotal move would ultimately pave the way for Nancy's own successful career in the entertainment industry.
Throughout her career, Nancy has had the opportunity to star in several television movies, including High School U.S.A. in 1983, Poison Ivy in 1985, This Child Is Mine in 1985, and Firefighter in 1986. In addition to her on-screen work, Nancy has also lent her voice to various animated shows, such as The Puppy's Great Adventure, which premiered in 1979.
