Sieber was born in St. Paul, Minnesota. He is a 1988 graduate of Forest Lake Area High School in Forest Lake, Minnesota, and he was inducted into the Forest Lake Schools Hall of Fame in June, 2011.

Stage

Sieber made his Broadway debut as Agis in the musical Triumph of Love with Betty Buckley and F. Murray Abraham. Following this role, he appeared as a replacement in the roles of Gaston in Beauty and the Beast, Trevor Graydon in Thoroughly Modern Millie and Billy Flynn in Chicago. Sieber played the role of Rapunzel's Prince and shared the role of the Wolf with Gregg Edelman in the revival of Into the Woods in 2002.

In March 2005, Sieber originated the role of Sir Dennis Galahad in the Broadway musical Monty Python's Spamalot. Sieber was nominated for a Tony Award for Best Featured Actor in a Musical for this role. After leaving the musical in July 2006, he made his London debut in the same role in October 2006, before leaving in early 2007. On June 1, 2007, Sieber sang tenor in the world premiere of Eric Idle's Not the Messiah (He's a Very Naughty Boy) in Toronto. On January 18, 2008, Sieber returned to Broadway to resume his role as Sir Dennis Galahad in Monty Python's Spamalot.

One of his most notable roles was Lord Farquaad in Shrek the Musical which opened on Broadway on December 14, 2008, after an out-of-town tryout in Seattle. For this role Sieber was nominated for a Tony Award for Best Featured Actor in a Musical, an Outer Critics Circle Award for Best Featured Actor in a Musical, the Drama Desk Award for Outstanding Featured Actor in a Musical, and the Drama League Award for Distinguished Performance. He played his final performance in this role January 3, 2010, when the Broadway production closed.

On March 11, 2011, Sieber replaced Jeffrey Tambor as Georges in the Broadway production of La Cage Aux Folles opposite Harvey Fierstein. Tambor left the role due to hip problems after only one month. In January 2012, Sieber starred opposite George Hamilton in the first national touring production of La Cage Aux Folles, this time playing Albin.

On January 31, 2014, it was announced that Sieber would be joining the company of Matilda the Musical on Broadway as Miss Trunchbull starting performances on March 18. However, due to a hand injury sustained in rehearsals, he did not start performances until April 18.

Sieber's off-Broadway credits include the revival of The Boys in the Band and Avow. He also appeared in the New York Philharmonic's production of Camelot.

Television

Sieber has starred in two television series: Two of a Kind with the Olsen twins and It's All Relative with John Benjamin Hickey and Harriet Sansom Harris. In early 2007, he was scheduled to film a pilot episode for an NBC comedy, Wildlife, playing an eccentric zoologist. The pilot did not make the final cut and was not picked up for the fall season. Sieber has also guest-starred in Pushing Daisies, Sex and the City and The Good Wife.

Personal life

While It's All Relative was being produced, Sieber came out as gay and said that he was happily partnered to actor and chef Kevin Burrows. They married on November 24, 2011, in New York City.

Sieber is involved with Broadway Cares/Equity Fights AIDS (BC/EFA) and has appeared in several of its Broadway Cares revues, among other events the charity produces. He teaches classes on drama and performance.
