Letscher was born in Grosse Pointe, Michigan, older brother to actor Brian Letscher. He attended college at the University of Michigan in Ann Arbor, MI where he was a member of the Sigma Nu fraternity and a drama major. He's married with two children.
Letscher got his first professional acting job with a role in Jeff Daniels' The Tropic Pickle, during the second season of Jeff Daniels' Purple Rose Theatre Company in Chelsea, Michigan. Letscher impressed Daniels enough that the veteran arranged a meeting for Letscher with Ron Maxwell, the director of Gettysburg. After appearing in a small role, Letscher took advice from Jeff Daniels and moved to Los Angeles. He quickly found work in guest roles on television.
In 1995, Letscher was cast as the naive television writer in the Nancy Travis sitcom Almost Perfect, which lasted for a season and a half. He went on to appear as series regular in Living in Captivity in 1998. The same year, he appeared in the film The Mask of Zorro as Capt. Harrison Love. He appeared in the miniseries King of Texas, The Beach Boys: An American Family, and Jackie, Ethel, Joan: Women of Camelot and TV movies When Billie Beat Bobbie and Stole Innocence. He also reunited with Daniels in Gods and Generals (the prequel of Gettysburg) and Daniels' directorial effort Super Sucker. Letscher also returned to The Purple Rose Theater in the world premiere of Landford Wilson's play Rain Dance.
In 2002, the comedy pilot Good Morning, Miami was picked up by NBC as part of Must See TV Thursday comedy block, but Burke Moses was replaced by Letscher and a second pilot had to be filmed. The romantic comedy sitcom featured Letscher as a smarmy former network anchor who was the primary romantic rival to main character Jake Silver (Mark Feuerstein) for the affection of Dylan (Ashley Williams). Despite the series receiving negative reviews, Letscher and Constance Zimmer were standouts in the series and eventually paired up as the combative couple in the second season. The show was canceled midway though its second season due to low ratings.
His performance in Good Morning Miami led to him being cast in the lead in the film Straight-Jacket, opposite Carrie Preston, about a gay Hollywood actor forced to marry a beard in the 1950s. His flare for classical farce also led to him being cast in the leading role of Capt. Jack Absolute in the Lincoln Center theater production of Richard Brinsley Sheridan's The Rivals. Letscher was raised for his spirited performance and his costar Robert Easton referred to Letscher as "a perfect classical actor."
Letscher joined the cast of Joey, recurring role on The New Adventures of Old Christine, and numerous guest starring roles. After appearing as a kind neighbor in Alan Ball's Towelhead, Letscher was cast inEli Stone, as the kindhearted older brother of a prophet, Nathan Stone. Despite low ratings, the dramedy series had loyal fans and critical acclaim, earning it a second season which included a larger role for Letscher. His work on Greg Berlanti's Eli Stone lead to his arc on Berlanti's Brothers & Sisters as a love-interest for the married Kitty Walker .
In 2012 Letscher starred in the series Bent and Scandal and was cast in the series The Carrie Diaries, as Carrie Bradshaw's widowed father Tom, which premiered in 2013. He will appear in the 2013 film releases of Atom Egoyan The Devil's Knot (about The West Memphis Three) and Spike Jonze's comedy Her, opposite Amy Adams.
In June 2007, Jeff Daniels' Purple Rose Theatre Company in Chelsea, Michigan, staged the world premiere of Letscher's original play Sea of Fools, a farce set in Joseph McCarthy-era Hollywood. Film director (and infamous HUAC name-giver) Elia Kazan is a character in the play. Jeff Daniels initially planned to direct the play but pulled out, allowing Letscher to also direct the play.
In 2009, his play “Gaps in the Fossil Record," staged at the Pacific Resident Theater.
In 2010, he cowrote (with Nipper Knapp and Andrew Newberg) and starred in the comedy pilot Gentrification, which won best writing at the Comedy Central New York Television Festival.
