Early Life

Daniela Ruah’s early life was a blend of two cultures and an early spark for acting. Though American-Portuguese, she was born in Boston, Massachusetts, to Portuguese parents who were medical professionals (her mother was an otologist, and her father was an ENT surgeon).

At the age of 5, the family moved back to Portugal, which became her primary residence while she was growing up.

So, her early life was shaped by her Portuguese heritage despite her being born in the U.S., and it was clear she gravitated towards creative pursuits from a young age.


Growing up in Portugal, Daniela Ruah attended St. Julian’s School before pursuing a Bachelor of Arts in Performing Arts at London Metropolitan University.

She honed her craft further at The Lee Strasberg Theatre and Film Institute in New York City.

Acting has been a passion for Ruah since her teenage years, and she continued to pursue it professionally while balancing her education in Portugal and abroad.


Daniela Ruah’s acting career has seen her journey through two distinct phases, beginning with her early start in Portugal and later transitioning to Hollywood.

At 16, she made her mark in the Portuguese entertainment industry by starring in soap operas.

After honing her craft through studies in London, she returned to Portugal, where she continued to excel.

She won the local rendition of Dancing with the Stars (“Dança Comigo”) and secured lead roles in various television series, short films, and theatre productions. Her dedication and talent have allowed her to make a name for herself domestically and internationally.

Daniela Ruah’s career took off when she joined the NCIS: Los Angeles cast in 2009 as Kensi Blye.

Throughout 14 seasons, from 2009 to 2023, she became a beloved staple of the show, showcasing her impressive action skills, humor, and dramatic acting ability.

While her role on NCIS: Los Angeles solidified her as a talented actress, Ruah also made guest appearances on other popular shows like Hawaii Five-0 and acted in various short films throughout her career.

In recent years, Daniela Ruah has expanded her talents beyond acting by stepping behind the camera to direct episodes of NCIS: Los Angeles and the miniseries “Contado por Mulheres.”
