Early life

Sagemiller was born in Washington, D.C. to a political activist mother and a professional American football player father, who played in the NFL for the New York Giants and the Washington Redskins. She attended Georgetown Day School. Her entry into the performing arts was at age 3 when she began studying tap dance, ballet, jazz dance and modern dance. She made her stage debut in To Kill a Mockingbird when she was 9 years old, and soon after she became a regular on her local stage. At 14, however, acting took a backseat to modeling after Sagemiller was scouted by Eileen Ford in a jewelry shop. She eventually left modeling to take an undergraduate degree in Art History at the University of Virginia.

Career

Shortly after graduation, she decided to return to acting full-time, and studied at the Stella Adler Conservatory, New York University's Stonestreet Studio and at Michael Howard Studios. Sagemiller appeared in Movieline magazine in August 2001. In November 2001, Sagemiller appeared in Gear magazine. In early career, she starred on number of teen films, like Get Over It and Sorority Boys, and was lead actress in 2002 thriller Soul Survivors.

On television, Sagemiller portrayed the character Michelle Ernhardt in the TNT series Raising the Bar from 2008 to 2009. After that series was cancelled, Sagemiller joined Law & Order: Special Victims Unit in a recurring role as ADA Gillian Hardwicke. She replaced Paula Patton when Patton departed the series after just one episode. Sagemiller was featured in ten episodes of the 12th season of SVU. She was replaced in the 13th season by Stephanie March and Diane Neal. In 2013, she was cast as a lead on Chicago Fire spinoff Chicago P.D., but left during pre-production.

Personal life

Sagemiller became engaged in July 2006 to her Sleeper Cell co-star Alex Nesic after he proposed to her in the South of France. The couple eventually married and have one child.
