Calvin Kai Ku is a professional actor, magician, clown, director, and playwright. He graduated from the University of California, Santa Cruz with a BA in Theatre Arts, where he focused on physical and technical theatre. During his education at UCSC, he performed with Rainbow Theatre, a multicultural theatre directed by Don Williams. He also directed a provocative production Untitled Until, a theatrical experience of poetry, dance, and music that expressed the cast's stories and emotional experiences. After studying under Patty Gallagher's Clown Studio, his interests in clowning led him to the Clown Conservatory of San Francisco directed by Jeff Raz. There, he studied with such artists as David Shiner, John Gilkey, Ronlin Forman, Joan Mankin; and trained in acrobatics with Master Lu Yi of the Nanjing Acrobats.

His love for magic began at an early age. Like all professional magicians, magic was originally a hobby for Kai. It was only until after much guidance from mentor and Misdirections Magic Shop owner Joe Pon that Kai would bring all he knew to the table to enhance his performance and become a professional magician. As a magician and theatre practitioner, he continues to discover how magic and illusions can bring life to all and every kind of performance.

Kai never fails to bring smiles and laughter to children. As a kid at heart, Kai loves entertaining kids and making them feel special. He has always had a great time working with children, which has made his kid's show fun for all.
