Koldyke worked as a high school English teacher and football coach in Chicago. His acting career received a jump start after a chance encounter with ''
It's Always Sunny in Philadelphia'' creator-star,
Rob McElhenney. Regulars at the same Venice cafe, he covered Rob's tab with a note that said he "thought his show was fantastic," and this exchange led to Koldyke's first TV pilot,

Boldly was not picked up, Koldyke went on to recur as Dale Tomasson in the
HBO series
Big Love and as Don Frank in
How I Met Your Mother for
CBS. In 2012, Koldyke starred as the lead character in the short-lived
ABC comedy series
Work It and later guest starred in
HBO's
The Newsroom. 2013 saw him star in another
ABC sitcom,
Back in the Game, opposite
James Caan and
Maggie Lawson. He had a significant arc on
Showtime's
Masters of Sex as teacher and football coach Paul Edley, and played male chauvinist Brent throughout
the final season of The Good Place. In 2021 he had a recurring role on season 1 of
Peacock sitcom
Rutherford Falls. Koldyke was seen on the big screen in 2016 in a supporting role for
Disney's
