Mary-Kate Olsen Bio
Mary-Kate Olsen (born June 13, 1986) is an American fashion designer, businesswoman, equestrian, and former actress who first rose to fame as a child star on the television sitcom Full House. Sharing the role of Michelle Tanner with her twin sister Ashley Olsen, she became one half of a cultural phenomenon that defined much of family entertainment in the late 1980s and 1990s.
Beyond her early acting work, Mary-Kate Olsen helped build a multi-brand fashion empire, co-founding The Row and Elizabeth and James, and launching more accessible lines including Olsenboye and StyleMint. She is also a competitive equestrian and a member of the Council of Fashion Designers of America.
Early Life and Background
Mary-Kate Olsen was born on June 13, 1986, in Los Angeles, California. She is the daughter of Jarnette Jones, a personal manager, and David Olsen, a real estate developer and mortgage banker. She is two minutes younger than her twin sister, Ashley Olsen, with whom she shares one of the most recognized sibling partnerships in Hollywood.
Mary-Kate also has an older brother, Trent, and a younger sister, actress Elizabeth Olsen. From her father’s second marriage, she has two half-siblings, Courtney and Jake. The family has Norwegian ancestry on the paternal side, while her mother’s background is of French, German, and Italian origin. Her parents divorced in 1996.
Mary-Kate attended Campbell Hall School in Los Angeles, graduating in 2004. After high school, she enrolled at the Gallatin School of Individualized Study at New York University, where she continued her studies alongside her twin sister.
Path to Celebrity
Mary-Kate Olsen’s path into entertainment began at only six months old, when she and her twin sister Ashley were hired to share the role of Michelle Tanner on the hit ABC sitcom Full House. The shared performance, a creative workaround to child labor laws, ran from 1987 to 1995 and made the twins recognizable faces across America.
As the twins grew, their work expanded beyond Full House. They starred in holiday television films including To Grandmother’s House We Go and Double, Double, Toil and Trouble, followed by theatrical releases such as It Takes Two, Billboard Dad, and Passport to Paris. In 1993, the family founded Dualstar Entertainment Group, a production company that managed the twins’ growing catalog of films, merchandise, and licensing deals.
By the late 1990s, the Olsen twins had become household names in the preteen market. Their likeness appeared in clothing, books, fragrances, magazines, and posters, and fashion dolls made by Mattel were sold between 2000 and 2005. Their continued popularity paved the way for Mary-Kate’s later transition from child star to fashion industry leader.
