Born in Mount Pleasant, Utah, Mike was a television commercial actor before moving into series and movie work.  In 1969, he was signed to play "Bobby Brady," the youngest son in The Brady Bunch.  This role would be the defining piece of acting work in Mike's life.

     During the run of The Brady Bunch, Mike took time during the series to do a variety of guest appearances on television shows and take roles in made-for-television movies such as The Point, The Boy from Dead Man's Bayou, Disney's Wonderful World of Color, Funny Face, and Dead Men Tell No Tales.

     Following the end of The Brady Bunch in 1974, Mike had a role in the film The Towering Inferno, the television series Isis, and a guest-starring role on the series Little House on the Prairie, Day By Day, the miniseries The Stand, and the television movie The Gambler V.  He also reprised his role as "Bobby Brady" for the two made-for-television movies, second series, and variety show.
