Born in Los Angeles to Valdez Flagg and Karen McDonald, Nina began studying gymnastics and dance at age three.  She would continue to train at Los Angeles School of Gymnastics (LASG) for 9 years.  Her dance training began with her mother and continued with other notable teachers such as Stefan Wenta, Yuri Grigoriev, Claude Thompson, Paul and Arlene Kennedy, Ron Brown, Otis Sallid, and Nzingha Camara.  At age twelve, Nina was introduced to director/choreographer Debbie Allen when she was hired as a dancer and gymnast for the 63rd Annual Academy Awards.  This experience would later lead to an extended professional relationship with Ms. Allen.


Nina went on to attend the Los Angeles County High School for the Arts (LACHSA) for three years.  It was during this period that she refined her dance techniques and enriched her artistic persona.  She excelled under the tutelage of Don Hewitt, Mary Bender, Rudy Perez, Don Bondi, KaRon Brown Lehman, and Hae-Kyung Lee.  After graduating high school in 1997, Nina began honing her skills in Hip-Hop dance while obtaining a Bachelor of Arts degree in Sociology with a Specialization in Communications from UCLA.  

During her senior year at UCLA, Nina was invited to teach on the staff of the Debbie Allen Dance Academy (DADA) in Culver City, CA.  

The following year after graduating form UCLA, Nina began training with Rennie Harris, Hip-Hop choreographer and artistic director of the Philadelphia-based company Rennie Harris Puremovement.   She went on to tour with the company for five years as a principal dancer.  In 2004, Nina also assisted Harris in setting a premier work on the Alvin Ailey American Dance Theatre entitled "Love Stories.”


In 2007, Nina began working with renowned dancer and choreographer Toni Basil.  She was hired by Basil as an assistant choreographer for Bette Midler's Las Vegas show at The Colosseum, The Showgirl Must Go On.  In 2008 Nina continued on as a part of Basil's collaborative team for the Tina Turner 50th Anniversary Tour.  

In 2011, Nina was once again given the opportunity to work with the Alvin Ailey American Dance Theatre. She was invited by Rennie Harris to collaborate on a full-length original work entitled “Home”, which is currently a part of the company's touring repertoire program.

In Summer of 2018, Nina returned to the Ailey company as Rehearsal Director for Rennie Harris' "Lazarus", the first hour long evening-length work in the company's history.  In the Fall, she transitioned to full-time faculty in the Cal Arts School of Dance where she began teaching courses in Hip Hop Dance Technique, Hip Hop Composition and Hip Hop Lab in addition to creating original repertory work for the school's partnership with Redcat Theatre.  In 2019, Nina had the pleasure of traveling to India on behalf of the Cal Arts School of Dance to expand the school's international presence and develop artistic exchange opportunities with dance artists in Mumbai, New Delhi, Bangaluru and Kolkata. 


In summer of 2021, Nina appeared in the documentary film “AILEY” which was released in theaters nationwide after its premier at Sundance Film Festival.
