Samantha Jo Moore was born on March 28, 1976, in St. Louis, Missouri, and grew up in Summit County, Colorado. Her parents are Bob and Wendy Moore, and she has one sister. She enjoyed dancing from a very young age. A public school student, she studied at the Summit School of Dance in Breckenridge under the school's founder, Kim Delgrosso, from age 7 to 18. She also attended the Perry-Mansfield Performing Arts School & Camp in Steamboat Springs for three summers. While attending Summit High School, she attended the Shelly True Dance Academy in Denver several times a week. She also participated in high school basketball, track, and gymnastics.

Moore moved to Los Angeles after graduating from high school in 1994 to pursue a career in dance. She attended the EDGE Performing Arts Center in Los Angeles on a scholarship from the Summit Foundation.

Moore was first hired by Carrie Ann Inaba to help out with some television dance projects, which led to her assisting with auditions for the reality show So You Think You Can Dance. She signed on for season 1 of So You Think You Can Dance as assistant to the choreographer. By season 3 she was choreographing dance numbers and by season 14 she was serving as creative producer. In 2018 she was named as a judge for Dancing with the Stars: Juniors. She was a guest judge (fill in), replacing Craig Revel Horwood on the first episode of Dancing with the Stars (Australian Season 17).

Among her television credits are Glee and American Idol (Fox), The Fresh Beat Band (Nickelodeon), Disney's 60th Anniversary Celebration (ABC), Modern Family, and "XQ Super School Live". Moore is an executive producer of NBC's musical comedy-drama Zoey's Extraordinary Playlist, as well as the show's choreographer. She also appears as the auditioner in episode 11.

Moore has choreographed dance numbers for several David O. Russell films, starting with Silver Linings Playbook (2012)—for which she trained actors Bradley Cooper and Jennifer Lawrence to perform a mashup of different dance styles—American Hustle (2013), and Joy (2015); she also did choreography for Leslye Headland's Sleeping With Other People (2015) and Disney's 2025 live-action remake of Snow White.

Her most notable work to date is the 2016 film La La Land, for which she choreographed all the dance numbers, both large-scale and small-scale. To choreograph the opening number, "Another Day of Sun", which took place in a traffic jam on a Los Angeles freeway ramp, Moore blocked out the action on paper and then began staging the moves using a group of ten dancers in a studio parking lot. The final scene involved 30 dancers, 100 extras, and 60 cars. Moore trained the lead actors, Ryan Gosling and Emma Stone, both dance novices, over a period of six to eight weeks. She emphasized emotion rather than technique, as Stone recalled:

"[Moore] tried to impart to us that, as much as we need to be technical and think of all of our steps, it's going to be about our faces. We need to see the joy and connection. We need to look at each other and smile at each other. We need to keep acting".
