Kaitlin Olson

Sweet Dee

Kaitlin Olson is one reason women are fast becoming a force in the comedy world. Well known for her unique blend of character and comedic acting, she has left her mark on some of television’s hottest shows.

The press has picked up on her performance as “Sweet Dee,” declaring her “the next queen of comedy.” Olson can also currently be seen as “Ashley” in her much-buzzed-about role on FOX’s New Girl.

Olson recently appeared in FOX’s film The Heat opposite Melissa McCarthy and Sandra Bullock and directed by Paul Feig. Additional feature credits include Universal’s romantic comedy Leap Year, in which she starred opposite Amy Adams, and the festival darling Weather Girl, where she starred opposite Jane Lynch and Mark Harmon.

Olson has been praised for crafting unique and memorable characters that recur on several shows. On Curb Your Enthusiasm, she plays Larry’s sister-in-law “Becky.” On FX’s The Riches, she played the one-armed neighbor “Hartley Underwood.” And on The Drew Carey Show, she was Mimi’s nemesis “Traylor” for two seasons.

Also known for her improv talent, Olson began her career with a highly-coveted spot in The Groundlings Sunday Company, a training ground for such comics as Will Ferrell and Phil Hartman. The showcase led to her casting in several improv/hidden camera shows, including Punk’d, The Jamie Kennedy Experiment and Meet the Marks. She was also a series regular on FOX’s Kelsey Grammer Presents: The Sketch Show.

Olson was born and raised in Tigard, Oregon, and graduated from the University of Oregon with a degree in Theatre Arts. She lives in Los Angeles with husband Rob McElhenney and sons Axel and Leo.
