Early life


Olson was born in Portland, Oregon,[7] on August 18, 1975,[4] to Donald Lee Olson, a publisher, and Melinda Leora, a nurse.[8] Shortly after her birth, Olson relocated with her family to Spokane, Washington,[9] then to Vashon Island, Washington, in Puget Sound, 13 mi (21 km) west of Seattle, where she lived until age eight.[10] Her family subsequently relocated back to the Portland area, settling in Tualatin, where Olson grew up on a farm.[11][12] Her father worked as the publisher of the Portland Tribune[11] from 2000 to 2001.[13]

At age twelve, Olson was involved in a serious bicycle accident involving a vehicle, resulting in a fractured skull requiring reconstructive surgery.[11][14] She graduated from Tigard High School in Tigard, Oregon in 1993.[13][15]

Olson studied theater at the University of Oregon, graduating with a bachelor's degree in theater arts in 1997.[8] After college, she moved to Los Angeles to pursue acting professionally.



Olson was a member of The Groundlings Sunday Company along with Dax Shepard.[11] She toured with the USO to Bosnia, Kosovo and Norway. In 2000, she made her debut television appearance on HBO's Curb Your Enthusiasm as the recurring role of Cheryl Hines's sister. Olson has also made several guest appearances in films and television series such as The Drew Carey Show, The Jamie Kennedy Experiment, Out of Practice, Miss Match, Family Guy, and Punk'd. She had a minor role in the film Coyote Ugly.[16]

In 2004, she was cast as Deandra "Sweet Dee" Reynolds in the FX sitcom It's Always Sunny in Philadelphia.[17] She also voiced Ethel in the first season of the Comedy Central animated series Brickleberry. In the 2013 film The Heat she appeared as a Bulgarian drug addict who engages in an exchange of cultural perspectives (and insults) with Melissa McCarthy's character.

She played a recurring role as Hartley Underwood, the "one-armed" neighbor in the FX series The Riches. In June 2016, the Human Rights Campaign released a video in tribute to the victims of the Orlando nightclub shooting; in the video, Olson and others told the stories of the people killed there.[18][19] Also in 2016, Olson provided the voice of Destiny in Disney's Finding Dory.[20]

She starred in the Fox sitcom The Mick, which premiered in January 2017. She also served as an executive producer for the series.[21] The second season of The Mick premiered in September 2017. Fox cancelled the series after its second season ended in April 2018.[5]

Olson appears in Hacks as DJ, Deborah Vance's troubled daughter.[22]
