Early life
Greer was born Judith Therese Evans on July 20, 1975, in Detroit, Michigan. Her mother, Mollie Ann (née Greer), is a hospital administrator, and her father, Rich Evans, is a mechanical engineer. Her mother was once a nun, who had left the convent after eight years, being "kicked out" for wild behavior, including owning a red bathing suit.

Greer was raised Roman Catholic and grew up in Redford Township and Livonia. She attended Churchill High School, where she was a part of the Creative and Performing Arts Program and graduated from The Theatre School at DePaul University in 1997 with a Bachelor of Fine Arts degree. She later adopted her mother's maiden name for her stage name, as several other actresses are named Judy or Judi Evans.
