Host Bio

Kristine Leahy serves as co-host for NBC's heart-racing obstacle-course competition series "American Ninja Warrior."

Previously, Leahy spent two and a half years working across various platforms in the CBS and Turner Sports family. She worked the college basketball sidelines for March Madness and was also a sideline reporter for CBS Sports Network's college football and basketball packages.

In addition, she filled in as a host on CBS Sports Network's show "Lead Off," contributed to KCAL's Dodgers pre-game show "Think Blue," anchored CBS-LA's "Sports Central" and covered the NBA playoffs, MLB playoffs and the Los Angeles Kings' run to the Stanley Cup. Along the way, she developed a passion for bringing out the human side of athletes, and portraying their stories through one-on-one interviews and features.

She also made a bit of history by becoming the first woman in California to call a horse race at Hollywood Park.

Leahy grew up in Chicago during the height of Michael Jordan's basketball reign, and at some point along the road to those six NBA titles, she got hooked. Not just on the Bulls, but on sports and competition.

After high school, Leahy moved east and earned a Bachelor of Science in Journalism from Boston University, where she was part of the team that created BUTV's first sports talk show, and co-anchored that show for three years. From there, she worked as a reporter and host for New England sports radio station WEEI before moving on to the 17-time world champion Boston Celtics, where she spent two years as a host and in-house team reporter at TD Garden and for

After the Celtics, Leahy spent one year as the lead sports anchor for Fox Boston, where she covered both a Stanley Cup and a Super Bowl, before moving out west.

She currently lives in Los Angeles and is on the board of the Variety Boys and Girls Club of Boyle Heights. She'd like to think that, wherever they are, she's made Michael, Scottie, B.J. Armstrong and the boys proud.
