Nikki Castillo(I)

Nikki Castillo is an actress and voiceover artist known for her work in television, film, and animation. Born and raised in San Diego, California, she began performing at age 5. She made her first professional theatre debut at 10 at the Old Globe Theatre, and at 12, starred in the title role of The Nightingale at La Jolla Playhouse, opening doors for career opportunities in theatre.

She attended the San Diego School of Creative and Performing Arts, majoring in musical theatre, where she honed her performance skills. After shifting her focus to Hollywood, she made her TV debut as Akina on K.C. Undercover (2015) (Disney) and gained recognition as Patty Logan on Scorpion (2014) (CBS). In animation, she is known as the voice of Betsy Spellman in the Emmy and GLAAD Awards Nominated series Summer Camp Island (2018) (Cartoon Network) and Pibby in the animated short Learning with Pibby: Apocalypse (2022) (Adult Swim). This summer, Nikki takes on the role of Lily Pak in Nickelodeon's brand-new 2D-animated comedy series Wylde Pak (2025), adding another exciting project to her growing body of work.

When not on a theatre stage, in front of a camera, or a voiceover studio, Nikki enjoys performing and participating in various charitable events and performances across Hollywood, L.A., and San Diego, particularly those benefiting youth-focused initiatives. In her spare time, she enjoys singing, dancing, playing drums, jamming to musical theatre songs, spending time with her brother and sister, and re-watching her favorite TV shows, like Sherlock, Doctor Who, Supernatural, and Gilmore Girls -- along with, of all things, NBA games. But when needing alone time, she finds solace in knitting, crocheting, sewing, folding the perfect origami unicorn, and constantly exploring new creative outlets to express herself!
