Raised on a farm outside Portland, Kaitlin Olson got her degree in Theatre Arts from the University of Oregon before she moved to L.A. to pursue acting. After spending some time with the legendary comedy troupe The Groundlings, Kaitlin secured guest roles on the hit comedies The Drew Carey Show and Curb Your Enthusiasm and the hidden-camera series Meet the Marks, Punk'd, and The Jamie Kennedy Experiment. In 2005 Kaitlin was cast as Sweet Dee in the FX hit comedy It's Always Sunny in Philadelphia, and in 2008 she got married to her co-star, Rob McElhenney. It may always be sunny in Philadelphia, but Kaitlin has yet to show us where the sun don’t shine on her. How about some brotherly love, Kaitlin?
